Fascinating 3D Printing Design Technique (#ziptiecity) Alan Reiner 2022-07-10 | I stumbled on a cool 3D design technique and have been playing it with the idea for the last week. Join me to discover how ZiptieCity can improve your life! UPDATE: I created a Fusion360 Tutorial on a new channel. I will be posting tutorials there regularly, as I've found it's a medium I can create good content quickly. Check it out if you're interested in how it was made! youtu.be/YKUK_rWfNnwP.S. - This technique has been in the wild for years, but it is new to me!P.P.S. - I never looked closely enough at the cutters I used in this video to realize they are not *actual* flush-cutters (they are almost-flush cutters).

All this to get to step one! #3dprinting #ratrig #vcore4 Alan Reiner 2025-05-07 | Ever wonder what goes into a DIY 3d printer? This will give you an idea of how to get to step one. Here's what I signed myself up for:- RatRig "V-Core-4" DIY 3D Printer- Independent Dual Extruders (IDEX)- High temperature bed: up to 200C (~400F)- Heated enclosure to 70C (~158F)For those curious about the magnets: the build plate is normally held in place by a sheet magnet. But most magnets demagnetize above ~130C (265F). And the standard adhesives to hold the heater and magnet sheet to the bed plate only work up to ~140C (285F). This is why the max bed temp of nearly all consumer printers is 115C-120C.These samarium-cobalt magnets keep their strength to 300C (572F), but I will have to CNC cavities in the bed and use high-temp RTV to embed them. I also bought a custom heater pad from Keenovo that uses "Lohmann" adhesive which is good 200C (continuous).This gets me closer to printing pure polycarbonate which is best with 160C bed (though the 70C chamber is still too low for large prints). A high-temp bed also serves as a decent enclosure heater.
Creative belt paths on RatRigs IDEX printer Alan Reiner 2025-05-01 | RatRig's V-Core-4 IDEX printer uses some creative belt paths and 4 motors in what they call "Hybrid CoreXY". The result is somewhat non-intuitive as seen by the way the toolheads move when I push the grantry.Notes: - IDEX: Independent Dual Extruders- This odd movement occurs with the bottom motor positions fixed, and the top Y-motors disconnected.
Cool laser-engraved patterns on anodized aluminum Alan Reiner 2025-04-21 | Anodized aluminum mounting plates/brackets for 3D printer I'm about to start building. My 22W diode laser (Creality Falcon 2 Pro) is *really* good at marking them by burning off the anodization.
Old coffee table converted to DIY sand table Alan Reiner 2025-04-06 | Completely custom sand table design, inspired by V1 Engineering's ZenXY (docs.v1e.com/zenxy), which is a DIY version of commercial sand tables like Sisyphus, Oasis, etc. This build included a lot of aluminum extrusion, 3d printed parts, custom aluminum motor brackets, and I CNC-cut the middle of the coffee table top for a 3/8" piece of tempered glass. Also, it's called a "sand table", but it actually uses baking soda for the medium, as actual sand is too coarse.The biggest issue I've had is that it's surprisingly difficult to get a flat surface before starting the job. It needs to be a very thin layer, which is difficult to get consistent. The circles at the top have those heavy ridges because it's too thick up there.Video on the build coming soon!
Use up those almost-empty filament spools! Alan Reiner 2025-03-25 | I've been printing tons of small objects like Gridfinity organizer bins. Great for using up those almost-empty spools, but I never know how much is left and how many I can print. Use this little-known slicer setting to fire and forget about it.WARNING: You can damage your printer if you mess up the clearances and the printhead collides with the previous object. Measure and observe carefully the first couple times you do it. Doing this in other slicers:Prusa Slicer: help.prusa3d.com/article/sequential-printing_124589Bambu Slicer: wiki.bambulab.com/en/software/bambu-studio/sequent-printSlic3r & derivatives: manual.slic3r.org/advanced/sequential-printing

Trolling my son with 3d printing Alan Reiner 2024-11-21 | My son wanted "Zelda: Tears of the Kingdom" for his birthday. I "wrapped" the gift card in PETG which has very good layer adhesion, making it difficult to break open. Use TPU to make it an even tougher challenge (it's kinda like printing rubber).
Speed printing fail - For the kids Alan Reiner 2024-07-31 | My kids had some friends who wanted to see how a 3D printer works. I showed them how it fails 😅. "Only" 750 mm/s, 20k mm/s^2 acceleration (It could probably MOVE faster, but I'm not sure it can PRINT anything at that speed)
Creality Falcon 2 Pro - FULL REVIEW (22W laser cutter & engraver) Alan Reiner 2024-05-31 | This is a really solid laser cutting machine for just over $1,000, but also has its fair share of issues. In this video I go over all the good, the bad, and the ugly of it. I also share a design I made to fix one of its biggest flaws.CORRECTION: I said in the video that camera calibration was pretty bad. I have since redone calibration with a properly aligned honeycomb bed on top of the slats, and kept the calibration pattern within the 400x400 square (instead of to the edge of the machine). The calibration is nearly perfect now!I reviewed the 22W version, but you can also get a 40W + 1.6W version, and pre-orders are open now for a 60W + 1.6W version. * store.creality.com/products/falcon2-pro-enclosed-laser-engraver-cutter?aid=zbkol01Use discount code: FNPALL10* Creality Honeycomb Bed: store.creality.com/products/honeycomb-workbench-for-laser-engraver-500mm-500mm* Link to my printable/cuttable slat stabilizers: printables.com/model/872184-falcon2-pro-slat-stabilizers-printable-or-laser-cu==TIMELINE==00:00 Intro00:51 Creality & Device Overview03:58 Unboxing & Build06:10 Product Tour07:36 Camera & Lens Calibration10:12 Cutting & Engraving Showcase19:31 Final Thoughts

Epic CNC Build in 10 minutes #mpcnc Alan Reiner 2024-04-06 | Okay, it's actually a REbuild. I turned my $600 MPCNC into an aluminum-cutting beast with about $500 in upgrades! Full enclosure, HGR15 linear rails, T-track for workholding, cable chains, anti-backlash Z drive, and a Raspberry Pi for CNC.js. * If you're new here, watch the first video showing how I built the original machine for $600: youtu.be/VFPeR6i1BvE* I will publish a discussion video about this build for anyone who wants to learn more about it: [Video TBD]* 3d model for the HGR15 linear rail upgrade (please read the description regarding stiffness): printables.com/model/835864-mpcnc-primo-c-hgr15-upgrade-files* The rails were cheap-but-good-enough Chinese rails from Vevor.

CREEPy 3D Printing Filaments #3dprinting #creep Alan Reiner 2023-09-01 | Break Every Filament Video: youtu.be/GZSm65tczh8In my Ultimate Engineering Filament Series I talked a lot about material "creep" but didn't really explain it. This #short shows why you should care.PLA might be technically one of the strongest [unfilled] 3D printing filaments, but it has some critical flaws for engineering applications, one of which is its extremely poor creep resistance. That means it shouldn't be used for constant-loading applications. Especially in environments above normal room temperature.This is why I have an enclosed printer and print primarily with ABS.
BREAKING Every Filament | PLA, ABS, PETG, PLA+ and More! #3dprinting #engineering Alan Reiner 2023-08-15 | The Ultimate Engineering Filament Series is here to teach you about ALL the different materials available for consumer 3D printers.

The prices I show are likely to track relative differences within a given brand/distributor, even though it's possible to find individual filaments cheaper if you're not picky about brand. In future videos we're going to see filaments that cost $100+ per kg!* It turns out that PLA+ is *NOT* a well-defined material. Watch the first 5 minutes of this video to find out more. Also the Slant3D channel is great in general, that guy is super knowledgeable and communicates/teaches really well: youtube.com/watch?v=S51BpxkIM6Q . That said, Duramic PLA+ is a well-known brand of PLA+, and this video shows it has concrete advantages over PLA, it just may not match other brands of "PLA+"

Most Annoying Computer to Fix Alan Reiner 2023-06-15 | Electronic wall art is hard to maintain. Have pity on me.NOTE: After discussions in the comments, it is apparent that it is almost never safe to open a power supply unit (PSU). There are high-energy capacitors that can maintain deadly (dis)charge even after the unit has been unplugged for a long time. I was actually aware of this and have a tool called a "capacitor discharge tool" for this purpose, but it seems like it's not worth the trouble and risk given how old it is. It looks like I'll be getting a 100% modular PSU, and just suck it up and do the full reassembly. If I have to replace the PSU after that, I can swap just the unit while leaving the modular cables in place.

Stowable Bed Probe for your Fancy 3D Printer Alan Reiner 2023-04-27 | Even budget 3D printers now come with a printhead-mounted bed probe that is used to measure where the bed is relative to the nozzle, and measure the shape of the build plate, to get perfect first layers. Most probes are permanently attached to the printhead and its measurements are affected by temperature which is a problem for an enclosed printer like mine. It can also collide with a warped part during printing because it is so close to the bed.This is the Euclid probe, a "stowable" bed probe that is consistent in high heat, and docked out of the way during printing. It also measures using a contact microswitch, unlike my previous inductive probe that can only detect metal/conductive surfaces.
Loose Screw... Alan Reiner 2023-04-18 | Never what you want to see when you go to check on your print. Luckily, that part is only relevant for initial printer calibrations, does not affect the print after it starts.

How does this 3d printing technique work so well? #shorts #3dprinting #notalithophane Alan Reiner 2023-01-25 | A random person on Reddit posted code to create these things! I bet they would look spectacular from a resin printer. Maybe I'll do that next...This technique is like a 2nd cousin to lithophanes. Lithophanes show images when light passes through them. These show images via light and shadows when illuminated from the left.The original Reddit post on r/3dprinting: reddit.com/r/3Dprinting/comments/10ill83/made_a_generator_of_these_more_in_commentsFor this to work it needs to be printed standing up so that the detailed curves are drawn in the XY plane. It would print horribly if printed flat because those detailed curves would be lost to the huge discrete Z layer height. Printing at a 30 deg angle preserves most of the necessary resolution while making overhang features easier to print.

It turns out there's a jumper you can change on each fan port to run 12V or 5V fans. So that buck converter was mostly just a waste of time and $2. * I also mentioned running the Raspberry Pi from the power supply (again mentioning a buck converter). Someone pointed out that the BTT Octopus Pro motherboard actually provides a stable 5V rail specifically to power a Pi or microcontroller, I wouldn't need to buck it directly from the 24V PSU. HOWEVER, as mentioned in the video, I didn't do either -- I just used a standard 5V/3A USB-C wall charger to power the RPi separately from the rest of the printer. That way it won't be force-shutdown when I turn off the printer.#ratrig #vcore3 #3dprinting #wiring #3dprinter

Though I'd probably have to slow down to about 15 min to match the quality.(Yes, this was supposed to be a #shorts video but I forgot to edit in portrait mode, whoops)This is not even close to a record (which is closer to 4min). Getting under 10min is just a benchmark for having a tightly tuned printer and knowing how to get it up to these speeds without the machine destroying itself. And it's also pretty fun to watch! I don't really plan to try to go faster as I'm worried about premature wear on this printer I have spent a lot of time and money building (like 50 hrs + ~$2k) Check out the following videos for more info about the printer:Part 0 - RatRig V-Core-3 Pre-build War Room: youtu.be/0dQpodKZjQ8Part 1 - RatRig V-Core-3 Mechanical Assembly Timelapse: youtu.be/rW1INp5_i1MPart 2 - RatRig V-Core-3 The rest: [TBD]Print Settings:* Speed: 325 mm/s* Accel: 20,000 mm/s^2 (this is where the 0-60mph-in-1.4s text comes from)* Square Corner Vel: 20 mm/s* Filament: Polymaker ASA filament @ 280C nozzle (ASA is very similar to ABS)* Flow rate: 41 mm^3/sPrinter Specs:* RatRig V-Core-3.1 (400mm)* Extruder: Orbiter 2.0* Hotend: Phaetus Rapido UHF with 0.4mm volcano nozzle
This AI Face Knows Your Halloween Costume Alan Reiner 2022-12-02 | I used the amazing Luxonis OAK-D camera for the edge AI processing to control motors for face following, and used OpenAI's CLIP model (related to DALL-E) to do costume identification. Both were basically off-the-shelf components, requiring no custom training for either task!

Creepy Halloween Prop Gone Awesomely Wrong Alan Reiner 2022-10-24 | Either I messed up the wiring or it is possessed!Most interesting is that flipping the lights (which I believe are on a different circuit) seem to be triggering the spasms. It's possible that the OAK-D camera on the top of his head is getting stimulated by the change in lighting and causing noise in the not-properly-wired servo signal pins.

Ultimate Guide to Flexible Filaments for 3D printing (TPU edition) Alan Reiner 2022-08-07 | Flexible filaments are awesome (Part 1). I printed and abused so many TPU parts on video that you'll feel like you printed them yourself. Learn some cool applications for flexible filaments and a cool slicer trick to help you print phone cases. Btw, this is only part of the story! This video is actually only like 1/3 of the adventure. I'll be covering more filaments, more cool tricks and TPU printing tips, in future videos, so make sure you subscribe!--EXTRA INFO--* I will include printing tips for TPU in the next video. Printing TPU 95A is possible on a Bowden extruder, but it may not be 100% reliable. Your best shot is to make sure the spool can spin freely, disable retraction, and print slow, like 10-20mm/s. I would guess the 90A and 85A variants are going to be more trouble than they're worth on a Bowden extruder (though I haven't tried). * I mention in the video printing 100% infill. I usually say "100%" in my head, but actually set it to 95% in the software. If your extrusion isn't calibrated perfectly and over extrudes you'll get a blobby mess at 100% (here's an example 100% infill print: bit.ly/3P2cIuB )==TIMELINE==00:00 - Introduction01:52 - TPU & Shore Hardness03:15 - Filaments 10104:50 - Cura Dual Extruder Trick 06:30 - Breaking Stuff10:52 - Fun 90A prints11:27 - Phone Case Slicer Hack14:13 - Phone Case showcase15:48 - CloserStuff in this video:* SainSmart Teal TPU (95A): amzn.to/3C8Ad2y* Polymaker Gray TPU (90A): amzn.to/3JUp1bv* NinjaTek NinjaFlex (85A): ninjatek.com/shop/ninjaflex3D Models:* Infinity Cube: printables.com/model/83187-tpu-fidget-infinity-cube
