Over centre mechanisms will make your designs more effective - Guide with examples @TeachingTech

Teaching Tech If you only learn to design with one mechanism, make it an over centre mechanism. In my opinion, this is one of the most versatile and effective mechanical systems you can utilise. In this video, we look at real world examples, and then break down the characteristics across a series of different designed examples. The final example is a CO2 dragster launcher, and stores enough energy to puncture a canister despite only needing the smallest nudge to activate.

Can Bambu Lab 3D printers be repaired? - 3D print mythbusting

Teaching Tech 2024-05-17 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

I’ve seen people complain in the comments that new age 3D printers like those from Bambu Lab are hard to work on, with components hidden in hard to reach areas. In short, these machines are not designed for disassembly and reparability in mind. In this video, I undertake a series of fixes in Bambu Lab printers and compare the process to more traditional designs.

Conditional PID tuning for maximum hot end stability - Is it worth it?

Teaching Tech 2024-04-26 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

I personally only tune my hot end PID for a single temperature wit the part cooling fan at 100%. But perhaps a lot more accuracy and stability can be found with conditional PID tuning. In this video, I take you through what PID is, how to tune it, and how to tube it for various scenarios and apply the, in the slicer. In theory this is superior, but in practise the effort may not be worth the meagre returns. What do you think?

Non-planar 3D printing in a modern slicer thanks to the community

Teaching Tech 2024-04-19 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Non-planar 3D printing is truly mesmerising to watch, and for the right type of model, vastly improves the appearance and surface quality. Thanks to the community, this feature is now available in a recent version of PrusaSlicer. In this video, I take you through the journey, the quirks, and the potential of non-planar 3D printing.

Hopefully this code can be ported into other slicers and developed even further. Even in its current experimental form it’s still worth having.

Carvera Air - Smaller, cheaper, but still smart and capable

Teaching Tech 2024-04-12 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Makera previously launched the Carvera desktop CNC, to much acclaim. Unfortunately, the machine was too expensive for many. In response, Makera now has the Carvera Air, a cheaper version that still retains many smart features. In this video, I test it out to determine the strengths and weaknesses, to let you make an informed decision.

This machine was provided to me free of charge by Makera for the purposes of making this video. All opinions expressed are my own. The machine will be donated to a local school where I am certain it will do a fantastic job.

PET bottle to 3D printing filament - A complete solution from Tylman Design

Teaching Tech 2024-04-05 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

There are more and more recycling options available for DIYers to use with 3D printing. In this video, I test a range of products from Tylman Design. They include the PETmachine (PET strip to PET filament) and PETwelder + Mr Winder (filament joining and winding). Although a certain investment is needed to get going, these products and the process itself can be very effective.

Both kits were provided free of charge by Tylman Design for the purposes of me making this video. All opinions expressed are my own. teachingtechyt.github.io/reviewpolicy.html

Home injection molding part 3: Making stuff! (kind of..)

Teaching Tech 2024-03-29 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

It’s time for some home based injection molding. I’ve had this machine since 2014, but it has been sitting idle for a while now, due to an error on my part. Previously, I attempted to mold some bespoke silicone washers to seal the machine, and did manage to mill a two part aluminium mold ready for recycled plastic. In this video, I make some further repairs and alterations and finally put through some shredded PLA with frustrating results. Is it worth more modifications and testing? At the moment, I think not.

Please note that this machine is sold to suit 110V mains voltage. In Australia we use 220V, and I’m pretty sure I removed one heater and converted the other. If you also use 220V, you would need to do the same or use a step down converter. It’s also worth noting that this machine was never intended to be used with this type of plastic. If I were to stick to the original Plastisol material, it would likely have been flawless.

Magneto X linear motors: Deep dive and performance testing

Teaching Tech 2024-03-15 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

After my first Magneto X video, many viewers had questions and requests regarding the linear motors. In this video, we take a detailed look at how they work, what each electronics component does, and stress test across a range of areas to see if linear motors are a worthwhile advancement for 3D printing, or just a gimmick.

Thanks to all of the people who asked questions in the first video, and to the Peopoly engineers who then answered my questions.

This 3D printer was sent to me free of charge by Peopoly, so I could provide feedback and suggest improvements for production models. There was originally no request to produce any videos about the Magneto X. After the first video, many viewers requested more information on the linear motors, prompting this follow up. All opinions expressed are my own.

Eliminate seams in your 3D prints with scarf joint seams - An exciting development!

Teaching Tech 2024-03-01 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Soon, the visible seam on 3D printed parts will be greatly diminished, thanks to a new development called scarf seams. In this video, I shine a spotlight on the work of the developers, as well as the work of the community in testing to make sure it works. All the details you need to test yourself are included, plus my own testing results across a range of 3D printers.

Can FOSS CAD compete? Trying out Ondsel (improved FreeCAD)

Teaching Tech 2024-02-23 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

I prefer to use free and open source options when I can, but when it comes to CAD I use the free but proprietary Onshape. I’ve previously tried but didn’t enjoy FreeCAD, but now we have Ondsel, an improved version that fixes problems and addresses community requests.

In this video, I compare Ondsel to FreeCAD, Onshape and even Fusion360 (this is the most I’ve ever used it). Trying to separate frustrations from being unfamiliar, I make a list of what works well, what is limited, and what still needs to be improved.

I really despise pointing out flaws in something free and open source, but I’ve tried to do so constructively, providing specific examples where these limitations are a problem. I’m sure some FreeCAd advocates will be upset over my conclusion, but the way it and Ondsel approach 3D modelling is quite different from Onshape/Fusion360/Inventor/Solidworks/SolidEdge/etc. They have converged on an intuitive and logical approach. FreeCAD/Ondsel deviates from this, but is it an improvement or hindrance?

Thanks to my patrons Derek and Novaplusplus for their assistance in making this video.

Field testing the Peopoly Magneto X linear motor 3D printer

Teaching Tech 2024-02-16 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

The Magneto X was announced in 2023 to much interest, due to its large build volume and innovative linear motor system. Importantly, all of the software was open source. When Peopoly offer me the chance to be part of the field testing team, I jumped at the chance to try and improve the product for eventual customers.

I know that some of the changes I made have definitely been included in the production printers, but I’m not sure if everything has. Fortunately, because it’s easy to alter things to your taste, users can easily replicate any changes that were not. I’m not sure who else was part of the test team, but I’m sure the improvements were a collaborative effort.

This 3D printer was sent to me free of charge by Peopoly, so I could provide feedback and suggest improvements for production models. There was originally no request to produce any videos about the Magneto X, but Peopoly did not object when I described this video. All opinions expressed are my own.

BTT Panda Touch - Convenient and Powerful, but with potential future issues

Teaching Tech 2024-02-09 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

The Bigtreetech Panda Touch is an add-on accessory for Bambu Lab printers, although it is best suited to the P1 series. With very fast installation and setup, you will add a Bambu Lab style UI as an alternative to the P1 series interface, as well as other features like portability thanks to an inbuilt battery. Perhaps most importantly, it offers control of print farms by allowing you to send commands and start print jobs on multiple machines at once.

In this video, we cover unboxing, installation, setup and functionality. All is currently well, but there are some other considerations you should include before purchasing.

This product has been provided to me free of charge by BTT for the purpose of making this video. All opinions are my own. It has been tested in accordance with my review policy: teachingtechyt.github.io/reviewpolicy.html

A 3D printing game? 3D PrintMaster Simulator review

Teaching Tech 2024-01-26 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

If you like 3D printing, why not enjoy it in a video game? In this video, I test 3D PrintMaster Simulator on Steam, a 3D print farm management video game. It promises building, upgrading and maintaining 3D printers, and using them to create customer jobs on command. The reality is a game full of potential that falls short on execution, so I’ve tried to provide some constructive feedback and suggestions to take the game forward.

I originally received a code free of charge to test this game from the developer. However, I also purchased a copy and gifted it to my nephew on Steam. My total gameplay was just over three hours.

Six incredible 3D printed projects for fun and discovery

Teaching Tech 2024-01-12 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

3D printings are becoming easier to use and capable of better results, so why not use them to create amazing projects. In this video, I showcase six hand selected projects primarily made with a 3D printer. I advise on how hard they are to print, assembly difficulty, hardware required and educational value.

All of these projects were worthwhile and satisfying, so thank you to the creators who released them free of charge. Also, a big thanks to my kids for their help, especially my daughter, who has all the hallmarks of a budding maker.

X1plus community Bambu Lab firmware - A win for everyone?

Teaching Tech 2024-01-05 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

UPDATE: Dr Tao has spoken with X1plus and users will be have a choice of firmware: blog.bambulab.com/rooted-the-good-the-bad-and-freedom-of-choice

Firmware for the Bambu Lab X1 3D printer has been reverse engineered, with a community version available in X1plus. In this video, I take you through every aspect in detail so you can decide if you would like to try it. Even if you don’t we explore how having a community variant of the firmware will drive new features, like we already have with OrcaSlicer and Bambu Studio.

In preparing this video I have been as diligent as possible, testing the firmware by printing absolutely everything I could on it. This amount to around 40 hours of printing using various filaments and slicers. I spoke extensively with X1plus devs, and even discussed this firmware directly with Bambu Lab CEO Dr Tao.

This video was checked for technical accuracy by the X1plus team before publishing. There are so many baseless accusations out there that it was important to ensure this video was factual. All information is accurate to the best of my knowledge in accordance with the X1plus team findings.

What will happen next? Let me know what you think in the comments.

Designing for vase mode - 3D design for 3D printing

Teaching Tech 2023-12-22 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.

In this episode, I demonstrate how to use simple shapes with helices and patterns to create repeating geometry suitable for vase mode 3D printing. The same concepts are repeated each time, with small variations, which means you can easily change aspects to experiment and see how the final result is altered. I also cover what vase mode is and how to activate it in your slicer.

This tutorial is near the end of a long series. It assumes you are already proficient with Onshape. If you try to follow this as a beginner, you will find it way too fast. Please see the earlier videos in the playlist to pick up the basics.

Bambu Lab A1 detailed test - ‘Just works’ 3D printing for a great price

Teaching Tech 2023-12-15 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Bambu Lab continues their disruption of the 3D printer market with the new A1 and AMS lite. Sharing components from both the A1 mini and more expensive X1/P1 series, the A1 aims to offer a smooth ‘just works; experience for a hugely competitive price. In this video, I conduct a detailed test to find what it does well and expose its weaknesses.

I would have liked the print quality, specifically the part cooling to be a little better, but even in this state, I feel this package offers an amazing all around experience. For comparison, the last printer I tested from a reputable brand had been out for months and still had significant issues and unfinished features. This 3D printer isn’t perfect but its smart features, ecosystem and support network remove many of the barriers to those new to 3D printing.

This printer was provided free of charge for the purpose of making this video. It was tested according to my review policy linked below. All opinions expressed are my own.

Open source filament pelletizer | Naomi Wu needs our help

Teaching Tech 2023-12-08 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

I am passionate about finding ways to recycle waste prints and filament, so I needed a filament pelletizer. None of those already published quite met my requirements, so I designed my own from scratch.

This video also aims to help Naomi Wu, a maker with the utmost integrity, who has put the community first repeatedly. Her actions have drawn negative attention from her government, and she effectively cannot post on social media anymore.If you need a threaded insert heat press, support Naomi by purchasing this one from her store:

cybernightmarket.com/products/heat-set-insert-press

This product was sent to me free of charge by Naomi for the purpose of testing, BEFORE I learned of her current situation. I was happy to pay for one, but she is very generous. It has been tested in accordance with my review policy and all opinions expressed are my own: teachingtechyt.github.io/reviewpolicy.html

Melting plastic waste into beautiful flat sheets on a budget

Teaching Tech 2023-11-24 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Finally, a decent end result when it comes to recycling 3D print waste into another product. Precious Plastic have some fantastic machines, but they are not intended for low volume users like myself. In this video, I show how a simple and inexpensive t-shirt heat press can be used to convert shredded plastic, or Bambu Lab purge poops, into uniform, flat sheets.

All equipment was purchased with my own money. Total cost: just over $200 USD. In future, I’m going to try melting down more types of plastic to recycle them. Let me know your ideas and suggestions in the comments.

Add 3D logos and text to your 3D prints easily with SVG emboss + Prusa XL update

Teaching Tech 2023-11-17 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

3D printing slicing software developers are producing fantastic new features very regularly. Today, we test out the new SVG emboss in PrusaSlicer. This guide covers what an SVG file is, where to find them, converting to SVG from jpeg, and different ways to apply them to 3D models before printing.

I also take the chance to update the performance of the 5 tool Prusa XL with the latest PrusaSlicer beta update. The ramming feature being enabled has made a significant difference, but there are still some areas which need attention.

Prusa XL update: Was the alpha firmware to blame?

Teaching Tech 2023-11-10 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Original video: youtu.be/C1a2c-qeTQw

Some commenters pointed out that my XL testing was all done wit the alpha release of the firmware and slicer. This is a fair criticism, so in the interest of fairness and transparency, let's rectify that.

The original video was already long and the problems I was seeing were posted on the forums by others BEFORE the alpha releases came out, hence why I didn't include a roll back test.

Hopefully this video confirms the problems are with the XL, not just the alpha firmware/slicer. Fingers crossed Prusa come through with some timely fixes.

The 5 tool Prusa XL is currently flawed, but I think it can be fixed

Teaching Tech 2023-11-10 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

A QUICK UPDATE video using non alpha firmware: youtu.be/bVY3S22L4EY
2nd update: Prusa have released a new version of the slicer with some counter measures for the blobbing and stringing. I will keep testing and update in a future video.

It’s been delayed for some time and the price hasn’t gotten any cheaper, but finally my 5 tool Prusa XL has arrived. Was it worth the wait? So far, the printer is quite undercooked. In this video I take you through my honest experience, including the problems myself and other owners are facing, as well as some of my intended fixes. Hopefully Prusa can release some updates to get this machine working as it should.

My apologies for my ranting in this video, but honestly I could have added more. Things like needing to turn down the crash sensitivity to stop false positives, the nozzle dragging across the bed after purging and leaving trails, the fact that you can’t adjust things like acceleration from the printer settings, the friction from the long ptfe tubes making it impossible to load tpu without pulling bits off, the PTFE tubes rubbing on the metal frame behind the tool posts, the USB flash drive being fussy with insertion angle.. The whole thing is just underwhelming.

This video is dedicated to my two dogs, Ricciardo and Sofia, who were both tragically killed by snake bite this week. Treasure your time with loved ones and pets, because you never know how long you will have with them.

Reducing waste from Bambu Lab AMS (lite) prints

Teaching Tech 2023-10-27 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Bambu Lab 3d printers produce really clean multi-material results. However, due to a filament cutting system that prioritises reliability, there can be an excessive amount of filament and time wasted. In this video, I explore some options for clawing some efficiency back. The gains aren’t huge, but are still worthwhile.

Thanks to my patron David who inspired this video during a great discussion.

Teaching Tech 2023-10-13 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

The main thing that annoys me about using the Bambu Lab P1P/P1S is the control panel. The screen is small and long strings of text have to be scrolled, plus the interface for things like setting the temperature is very clumsy. Thanks to developer experiments, the xtouch touch screen interface is now available, for a total cost under $10.

I first tried this upgrade back in August, but there were some issues that diminished the experience. Experiments has since developed xtouch to a really polished product. I am very thankful for their efforts!

Four bar linkages for 3D printing - Guide with examples

Teaching Tech 2023-10-06 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Building on my previous breakdown of over centre and cam mechanisms, in this video we explore four bar linkages. This is another versatile mechanism that can be configured in numerous ways. In this video, I design and 3d print a modular version so these configurations can be tested and demonstrated. We explore scenarios for introducing motors and servos too.

Orca Slicer getting started guide: A slicer for all of your 3D printers

Teaching Tech 2023-09-29 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

A while back, I discovered Orca Slicer, a fork of Bambu Studio that could handle Bambu Lab 3D printers as well as other Marlin and Klipper machines too. Since then, it has evolved and I have adopted it as my primary slicer.

My patron Derek asked for a beginner’s guide on migrating to Orca Slicer. In this video, we cover download and installation, first run, basic slicing, security tips and other useful features. There is plenty that’s beyond the scope of this video, but hopefully enough is covered to let you hit the ground running.

HueForge getting started guide: Filament painting with your 3D printer

Teaching Tech 2023-09-15 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Amazing, photo-like 3D prints without a multi material 3D printer? That’s exactly what Hueforge can deliver. Taking advantage of the fact that filaments aren’t opaque and instead let light transmit through them, it combines an image to 3D STL function with predictive colour blending to achieve the required result. In this video, I take you through an introductory tour of HueForge, so you can decide if it is something you may wish to try yourself. You should!

I purchased this software with my own money. All opinions are my own. Thanks to Cory for requesting the video.

Home injection molding part 2: Machining a mold

Teaching Tech 2023-08-25 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

It’s time for some home based injection molding. I’ve had this machine since 2014, but it has been sitting idle for a while now, due to an error on my part. Last time, I smashed some stuff to get it unseized. This video is all about mold making. Including 3D printing molds for silicone, and CNC milling aluminium molds for plastic using the Carvera desktop CNC. Not everything went as planned..

Please note that this machine is sold to suit 110V mains voltage. In Australia we use 220V, and I’m pretty sure I removed one heater and converted the other. If you also use 220V, you would need to do the same or use a step down converter.

Master infill to take your 3D prints to the next level

Teaching Tech 2023-08-11 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Infill is probably an aspect of 3D printing we rarely consider beyond setting the density. In this video, we take a deep dive into infill, looking at what parameters best suit a range of situations. Whether you are trying to create strong prints, fast prints, or prints that use minimal filament, this guide has you covered. We also explore some more experimental options to drastically alter the appearance of our models.

Home injection molding part 1: Machine tear down and repairs

Teaching Tech 2023-08-04 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

It’s time for some home based injection molding. I’ve had this machine since 2014, but it has been sitting idle for a while now, due to an error on my part. In this video, I start the process by cleaning and repairing to get it almost back to working order.

Please note that this machine is sold to suit 110V mains voltage. In Australia we use 220V, and I’m pretty sure I removed one heater and converted the other. If you also use 220V, you would need to do the same or use a step down converter.

Hopefully the new o-rings work well, but in any case, I’m considering casting some high temp silicone washers so I can push the temperature as necessary.

In part 2, the plan is to machine and mold and create something.

Remix STEP files to suit your needs - 3D design for 3D printing

Teaching Tech 2023-07-21 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.

In this episode, I demonstrate how to upload and modify STEP files into Onshape to suit our specific needs. This rugged box model is very well designed, so it is satisfying to tweak it to fit different objects. I’m going to do just that for some delicate electronics.

Design like a pro with shadow lines - 3D design for 3D printing

Teaching Tech 2023-07-18 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.

In this episode, I demonstrate how to alter the mating surfaces of multi part designs to include a shadow line. This technique is used in most professionally produced injection molded parts and offers a range of benefits.

Hero Me part cooling system - Modular, capable and super compatible

Teaching Tech 2023-07-14 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

Previously, I had invested quite a bit of time and effort into modifying a Creality Ender 5 to have an enclosed and actively heated chamber. The addition of the Bambu Lab X1C to my studio has made the Ender 5 redundant, however, so in this video I remove all of the heated enclosure parts, and fit the Hero Me gen 7 part cooling system.

If it feels like at some times I’m being vague, that’s on purpose. The documentation is thorough but not free, so I had to make sure not to make it redundant. I’d recommend anyone undertaking this upgrade, to pay for the detailed PDF guide at a minimum.

The pros and cons of 3D printer cloud connectivity

Teaching Tech 2023-07-07 | Check out my 2nd channel, TT Racing: youtube.com/@ttracingYT

More and more 3D printers are being sold with cloud connectivity. In this video, we debate the merits of this approach. While there are some worthwhile gains in convenience, there are also some alarming possibilities too. Will the annoying trends that plague games and mobile apps find their way to 3D printing? Let’s hope not.

Please share in the comments any topics I may have missed.
