  • Ok, so a vast majority of 3d printers do not connect directly to a PC these days. They have a self contained microcontroller.

    The workflow is:

    1. You design or download a 3D model you want to to print.
    2. Open the 3D model in a slicer software. The slicer takes a 3D model and, using a profile designed for a specific printer’s nozzle size and controller, converts the solid volume of the model into G-Code, or machine readable code that is a series of coordinates and move rates. This tells the printer where and how to put plastic.
    3. Export the G-code to a .gcode (or other) file. Save that file onto an SD card.
    4. Put the SD card in your printer.
    5. Select the file on the printer display and away you go.

    Now, some printers use a network connection component, eg Bambu printers have a wifi adapter. This let’s them download firmware updates and receive print jobs from a computer remotely without needing to move SD cards. This does require the right software, e.g Bambu printers require proprietary Bambu Studio (or it’s open source fork OrcaSlicer) that has the networking module to talk to it. This doesn’t require special driver setup though.




  • I have a Creaform MetraScan 750 at work. It’s pretty neat, can get 0.005" accuracy or less out of it. We also have a HandyScan with single line mode for very small parts.

    Granted, at $150k system cost, it is slightly out of the layman’s budget range…

    An OpenScan kit is something that’s been high on my list for hobby purchases for a while. It looks pretty functional from the YouTube videos I’ve seen and my printer is fully capable of making the frame.





  • This is an interesting conundrum.
    On one hand it would help locate foreign agent bots/bad faith actors faster and recognize vote manipulation by bot farms.
    On the other it will lead to even more account-stalking problems, user drama, and would further enable vote dogpiling if you see certain known users voted a certain way.

    I’m inclined to say no. They are already “public” if one wants to put in the effort to admin a standalone instance or run alts on multiple services they can see if they care- I personally don’t really care

    NGL, I feel that Prusa has lost their edge.

    Yes, they are still the pioneers, and yes, their company still has strong morals and a open-source culture that is lovely for the community.

    But- the market has left them behind. XL is a great idea but awfully expensive and maybe not perfectly implemented. MK4’s are great-ish, but get their pants beat off in speed and quality by a P1P that’s $300 cheaper. I know running manufacturing in countries with functional human rights incurs a significant cost, but unfortunately the fickle “free” market that cares more about getting plastic onto a build plate doesn’t take such things into account frequently enough. And that’s worrisome for Prusa’s future.



  • 100%. I’ve printed some cool stuff and some stupid stuff, as well as a bunch of functional parts that have improved my life around my house. More importantly it’s given me a huge creative outlet to get more and more outlandish with my CAD designs and push my experience limits, which is great because that helps me be a lot more efficient at work.

    Financially it was a total waste of money but that doesn’t matter when it’s a hobby. A hobby with practical marketable skills, and also the ability to let me prototype some independent ideas I’ve been brewing for a while to maybe sell for some side cash…
