It’s time again for me to replace a couple 3D printed pieces of my Lulzbot Mini printer, so I’ve captured the details here of melting heat-set inserts into PETG 3D printed parts.Continue reading Adding Heat-Set Inserts to your 3D Printed Parts
I recently bought and assembled a Prusa i3 MK3 kit, and decided to prepare for printing emergencies by printing a full set of replacement parts as soon as the printer was working well.
I’d found, in using my other printer, that even high-quality printed parts do eventually delaminate under stress: after two years, that printer’s X and Y idler supports developed fractures. Because I couldn’t print the replacement parts (and because doing the replacement seemed daunting at the time), I wound up sending that printer to the factory for repairs.
I’ve also seen notes and videos from people recommending a set of replacement parts as a backup, in case you break a part while adjusting or doing maintenance on your printer. Having replacement parts on hand is also a good preparation for helping a 3D printing friend when their printer breaks.
