Difficulty getting good precision

I have a reprap printer with 0.3mm nozzle. It prints quite well, I am really surprised with quality of all the surfaces and the general precision of the parts printed. BUT I HAVE a problem: when making (for example) a 10mm x 10mm x 10mm cube with a…

Reprap variants with servo motors rather than stepper motors?

In a discussion about motors with a friend who used to work in the robotics industry, he told me that he despised stepper motor systems, as every stepper based system he had worked on required a bunch of hacky software fixes to make the system…

Delta 3D printer extruder?

I've never gotten a 3D printer, nor do I know very much about them, but I'm thinking of buying a delta 3D printer kit for around $450. When I looked online of some disadvantages of Delta printers I found that they typically don't have Bowden…

What makes 3D printing noncompetitive for medium production runs?

I've been 3D printing as a hobby for a couple of years now, and have always heard how 3D printing is great for prototyping, but once you get beyond 10 or 20 pieces it's just not cost competitive with other technologies. I just accepted this to be…

Lower BuildTak adhesion

I'm having a similar issue to this one: I have retrofitted my printer with a BuildTak sticker. I'm printing PLA at 60°C bed temperature - currently using a 0.3 mm nozzle, but I had similar issues with the 0.4mm nozzle before. If I bring the nozzle…
