Which material "creeps" (plastic deformation) the least (or nothing at all) under pressure after being printed?

I would like to build a standing shelf where the supports which hold each successive plank are 3D printed (to obtain special shapes). However, I read that PLA flows under constant stress/pressure. Still, this doesn't stop the author of the article…

Is this model feasible to print?

I have a 3D model that I'd like to print. This is my first project, so I'm trying to decide if I'm getting in over my head. Here's the model rendered with Blender: If I throw it at a commercial printing shoppe, is it going to be fairly straight…

How do I remove a 3D print stuck to the glass build plate

I printed a model and now I can't remove it. I have been chiselling away with a putty knife and made little or no progress. I even heated the bed up to 70 °C. That really didn't seem to help. Last time, I put it in vice, and tried to free it that…

Would a steel, instead of an aluminium, plate be reasonable?

I have a Flashforge Creator Dual. One corner of my print bed is warped down. I am thinking about having a steel print bed made so it would tend to stay flat. Has anyone tried this?

Marlin 2.0 Firmware temperature jumping on LCD when trying to configure UBL

Flashed Marlin 2.0 on my Folgertech 2020 Prusa i3 variant. Calibrating seems to have gone smoothly until I tried to set up UBL. Saved the mesh into EEPROM with the M500 command after a G29 P1. When trying to do a test print with G26 P10, the…

How to wire for AC mains voltage relay, when printer board is connected to AC-charging laptop computer?

I know this will be a really obvious question to some people, but I have bricked about 3 boards doing this so I want to be certain before I brick a fourth. I don't have a lot of experience working with AC voltage, especially crimping / hacking it…

Is it possible with current 3D printers to print a sound trace?

Is it possible with the accuracy of current 3D printers to print a sound trace? On a vinyl record the grooves in the record are an encoded sound. Is something like this doable with 3D printers? If Vinyl-like isn't possible, could a sound be…

What is the thermal conductivity of various 3D printing filaments?

Thermal conductivity is how well a plastic conducts heat. Most plastics don't conduct heat very well at all, which is what allows them to be 3D printed. That being said, there are a lot of potential use cases for highly thermally conductive…

Why don't 3D printer heads use ceramic inner walls?

Why don't 3D printer heads use ceramic inner walls? PTFE tubes melt with high enough temperatures and all metal ends risk jamming as heat makes its way up the head.

Getting better support than Slic3r generates

I found a nice model for a ship from the game "Eve". It doesn't have a flat bottom, so it needs support material. But Slic3r generates several dozen tiny support pillars, and one by one they break loose from the build plate. As they get tall, the…

Are there many differences between Ultimaker Cura and FlashForge FlashPrint slicers?

I recently bought a 3D printer called Dreamer NX from FlashForge. The dealer told me to use FlashPrint software that belongs to the FlashForge printer manufacturer. But, many people advise me to use Ultimaker Cura. Are there many differences between…

How to fight lots of stringing with PLA at low temperature (185 °C)?

I just got my first 3D printer (Creality Ender 3) on Friday, 2 days ago. It works great, but for some reason I'm getting a lot of stringing on my prints, especially the ones where the extruder head has to move a long distance between columns/posts,…
