Should you buy a used 3D Printer?

Should you buy a used 3D Printer on sites like Facebook Marketplace or eBay? What are the Pros and Cons? In this video, I go over that, aimed at both experienced 3D printer owners and newbies looking to save some money on their first 3D printer!

Nice video. I have 12 machines, 8 I bought on eBay marked "as is, for parts only". For example I bought 2 Lulzbot TAZ 5 machines. One, the owner took it apart, for some reason, and did not rewire the Rambo card correctly, the frame was all messed up, even the support for the lead screw one side was upside down. The other the LCD screen the turn knob broke off, the print bed glass was shattered, etc. $200 for each, the one needed no replacement parts just reassemble correctly and Rambo card rewired. The other cost me about $200 for the LCD and new heated bed, although I upgraded it to a magnetic, flexible PEI sheet. So the extra money on that one included an upgrade. I also run one with an E3D titan for 1.75mm filament and .4mm nozzle. The other I run a Moarstruder for 2.85mm filament and a massive 1.2mm nozzle for very fast prototyping. I bought 2 Snapmaker A350s each for $400, variety of issues and maybe $200 for each and both work great. One I have set up for CNC which I did spend extra money for the rotary CNC. The other I did spend extra for the 10w Laser but both work great at some great savings also. I bought some crazy machines no one has heard of when I first started, 5 years ago. Got a Dobot Mooz 2 which that one I did buy at full price BUT on Amazon Prime day for $250 off full price. Then I bought a Dobot Mooz 3 which runs 3 extruders and can change and blend the colors. Got that for $70, full retail was $899. The owner, I guess, didn't know how to set up CURA for a Delta printer and he did crack the heated bed. I got it thinking it would just be a parts machine and configured it as a delta printer on CURA as they had no Dobot Mooz 3 profile and it worked perfectly. I just fixed the heated bed. I also have a SIndoh DP200 which they no longer make or support. I think the owner was frustrated with the expensive proprietary filament spools. Got that machine for $500 with 15 filament cartridges, which was an insane deal. I contacted Sindoh and they had a firmware upgrade to allow it to run 3rd party filament. I did build a VORON 0.1 printer from someone totally stuck with the firmware, klipper, moonraker, and mainsail installs. Got that for $250 and just figured out all the firmware, software, printer conf settings, etc. The VORON is a brutal build. And I have an antique that cost $1400 new in 2013 called a Cubify Generation II made by 3D systems. I got that for $70 thinking it would be a cool antique looking thing. It needs a ,cube file vs. the ,gcode file. Shockingly 3D systems had an archive site with the Cubify slicer. So, even that works. I still use the 2 Lulzbots, the 2 Snapmakers bit not as 3D printers, as a laser and CNC machines. The Sindoh DP200 is enclosed for I use that for ABS, the VORON is fast but much smaller build volume vs. the Lulzbot and Snapmaker, so I use that for making gears as I do mostly robotics with Arduino, Raspberry, and Maestro. And I have a couple other printers floating around. I guess I am a real DIY guy. And if both of my Lulzbot machines are buys and I am printing PLA I just swap over one of the Snapmakers, which I upgraded to glass beds, I put on the 3D print module and 3D print with the Snapmaker. 3D Printing is cool but I do either robotics, functional parts, or I tend to fix things that broke. For example, my security camera mount broke. You can't just buy a mount. I modeled a replacement mount, as I don't have a 3D scanner, printed it and remounted the camera. I find uses for the printers.

How about used makerbots?

I honestly haven’t used one but I believe they have a proprietary print head type so you might want to do some research there.
