Awesome project! I've always wanted to build my own 3D printer. How long did it take you?
johnsmith 6 months ago next
It took me around 6 months with a few hours each evening and weekends. A lot of troubleshooting and fine-tuning along the way.

Where did you source your parts? I've been struggling to find some high-quality components.
johnsmith 6 months ago next
I got most components from McMaster-Carr, The Rod Shop, and OpenBuilds. For custom parts, I used a local machine shop. I'm working on a BOM and will post it soon.

Impressive, I am curious about the materials you used. Can you share more details?
johnsmith 6 months ago next
Sure! I used aluminum extrusions, linear bearings, stepper motors and a custom-built PCB with a 32-bit ARM microcontroller. I can share a list of components and suppliers if it helps.

Thanks! This project is on my to-do list. Btw, any software recommendations?
johnsmith 6 months ago next
I suggest PrusaSlicer, Cura, and Repetier for different functionalities. Don't forget to setup OctoPrint if you need remote monitoring.

What’s the build volume you achieved?
johnsmith 6 months ago next
The print volume is 300 x 300 x 400 mm with a print speed up to 150 mm/s and an acceleration of 3500 mm/s^2. I can reach amazing detail in my prints with precision of 50 Mikrons.

What is your estimated cost for the project?
johnsmith 6 months ago next
Total costs amount to around 1300 - 1500 USD for better quality components and machine shop costs. But you can easily build one for less if you are willing to save.

I heard 3D printers need heavy maintenance. Is that true for this build?
johnsmith 6 months ago next
No, not really. I suggest cleaning the removeable build plate, tightening any loose screws, checking and changing belts and proper calibration, once in a while.

Are there any challenges you want to share during development, like biggest issues and breakthroughs?
johnsmith 6 months ago next
The biggest issue was aligning and calibrating the stepper motors and belts - ensuring they all move smoothly. Breakthroughs: DIY filament management was a game changer and lm8uu linear bearings provided smoother motion.

Can it also be used to print any object using conductors like copper?
johnsmith 6 months ago next
Yes, however, with certain PLA or ABS variants, 1.75 mm or 3 mm filament, you can achieve minor conductive properties. There are other materials you can use for better conductivity though.

Nice! Do you have any example prints or photos of your 3D printer?
johnsmith 6 months ago next
Sure! You can find them here: (put_link). I included some high-resolution images that show details like the precision and motion system.
