A 3D scanning photogrammetry rig that automates image capture and post processing, for free, and open source! It sounds too good to be true, but based on my testing it’s not. After you purchase the hardware kit, everything is free.
I’m not a patient person when it comes to prep for painting or 3D scanning, so the fact that my results were impressive tells you that this product is easy to use for almost everyone.

![Full colour first layers on your 3D prints part 2 - Laser and inkjet printers too!
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
Johan from Nerds.ph has created an amazing process that combines full colour 2D printing with 3D printing, using sublimation. In part 2 of this guide,we test ways to avoid the need for a sublimation printer, by utilising regular colour laser and inkjet printers. I also test out some of your suggestions from part 1.

![Sovol SV04 IDEX: Capable with one big but fixable problem
You requested it and now we have a review of a IDEX 3D printer. IDEX stands for independent dual extruder. The machine has two hot ends, which can print two colours, two materials or even two models at a time. In this video, I thoroughly review the SV04 to see how it performs.
If the slicing profile was up to scratch on this printer, I would only have the minor complaints to discuss. Since a slicer profile is free to change and can fix the primary problem, I give this printer a thumbs up overall.
This machine was provided free of charge by Sovol for the purpose of review. All opinions expressed are my own.

![What each 3D printer firmware does well, and where it needs improvement
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
Incredible advancements in firmware have driven the significant growth of 3D printing at home. There are four main 3D printer firmwares available, and each has pros and cons. In this video, I examine what each does well, and look at areas where they could improve the user experience, especially for beginners.
Let me know in the comments if you agree with this critique.

![Endless 3D printing - DIY conveyor belt delta bed
Since I tested the Creality CR-30 Print Mill, I’ve wanted a 3D printer that could eject finished parts and continue through a print queue autonomously. In this video, I take you through how I converted my FLsun Super Racer delta 3D printer to do just that. Everything is free and open source. A separate video is provided to cover the step by step assembly.
Still some work to do to make it foolproof but as a proof of concept I’m very happy.
Thanks to Adam from Powerbelt3D for offering tips and advice in my design process. Thanks to my patrons for assisting with the list of part ejection capable printers.

Bambu Lab’s recent security update blog posts have attracted a lot of negative attention. Some of it is justified, and some is pure fear mongering.
