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…

I woke up this morning with my 20 hour long print failed around 15 hour in. I checked the octoprint console, and saw a very weird temperature graph. Later found out thermal runaway protection kicked in, and I thanked the gods for having decided to…

Random lines are being printed?

I recently got a Creality Ender-3, and tried printing a few things for some tests. I’ve printed a cube and just printed a cylindrical tube today, and I notice each time, it adds this random line on the left and a sort of outline around the actual…

How does slipping Bowden tube affect retraction or does it at all?

I have an Ender 3 Pro with upgraded Bowden capricorn tube. The tube will move approximately 1-2 mm during normal operation, though it will not come out of the coupler at all. I have read that the movement if unchanging (constant movement of 1-2 mm)…

I was trying to print parts for a small CD-ROM drive based plotter based on this thing https://www.thingiverse.com/thing:3521286 But as tolerances are very small and need to match the existing parts, I realized that my printed parts are actually a…

Bumpy first layer with PETG

When I print with PLA, I get a perfect first layer. However, when I print with PETG, the first layer looks like this: I've read all the info that suggests reducing the temp, speed, and increasing retraction... I've done all that which has improved…

Out of the blue my A6 printer displays a ERR MAXTEMP BED error and shows about 100 degrees on the bed even when just powered on. A quick thermistor check shows that it's working properly : about 80 kOhm at room temperature, similar to other units…

Does matching whole Z-motor steps for layer height actually matter on Ender 3?

This question asks about computing the fundamental layer height unit for full Z-motor steps, on the basis of a theory that layer thickness can be inconsistent if the height is at different micro-stepping positions on different layers. The specific…

How to calculate the proper layer height multiples?

We all know, that the best layer hight is, when you have multiples of full steps. If it is not, sometimes steps get skipped and end up bad layer-to-layer adhesion when one height step missed a tiny bit and then the next catches up, creating an…

Why are delta bots so finicky?

I've had my anycubic kossel for a good while now, and whenever I print something, it seems like it falls out of calibration very quickly. The biggest example is that the prints tend to scale up as the print progresses, or maybe the print starts to…

Creating "pie slice" in OpenSCAD?

When making a cylinder, sometimes I need to only take a pie slice. I'm currently using this neat trick to make pie slices for angles under 90 degrees. However, I have need of a few angles over 90 but under 180 degrees. Is there a way to…
