Serious safety concerns with living in same room as PLA 3D Printer?

I have an Ender 3 which I primarily use for printing with PLA. I haven't branched out to other materials yet. :) I've done some research into PLA fumes and airborne particulates which seemed to mention that PLA is mostly safe, but ABS is rather…

Which is the difference between MK6 and MK8 and even MK10?

I made and assembled my own 3D printer two years ago and I notice that some extruders are MK6 and MK(*whatever). Some of them has the block fuser horizontal and others vertical, then uses a nozzle longer. The block heater that I made was an aluminum…

What are the pros and cons of collecting parts yourself, versus getting a DIY kit and then modifying it?

I'm thinking about buliding my own 3D printer from scratch. Is it better to buy a starter DIY kit and try to build your printer around it, or to order separate parts for printer, and then to combine a printer?

Would 3D printing multiple copies at once saves time?

I am wondering - of course if the 3D printer's bed big enough - printing multiple copies of the same print could save me significant amount of time in a small production line, excluding minor wastage such as setup time, post-processing time,…

Are there biocompatible materials available to the general public?

I am currently working on parts for a custom prosthesis. My main concern at the moment is to find biocompatible materials that can be 3D printed from a UP or a Reprap. The piece would need to be in contact with the skin for extended periods of time,…

How does the sizes of nozzle diameter and the Z-axis layer resolution work?

I have a 3D Printer with 0.4 mm (400 micron) nozzle length and the printer guide suggests that it can print up to a layer thickness of 60 micron and has a accuracy up to 100 micron. What I'm trying to understand is that, how does the 0.4 mm nozzle…

Ender 3 nozzle homes off the bed in the Y axis

I just received my new Creality Ender 3. I was going through and checking/adjusting everything for alignment, and I noticed that when you "auto home" the print head, the nozzle stops off the front of the print bed by 5-10 mm. Is that normal? Is it…

Print only part (fraction) of a model

I've made a 9H-printing model tonight, and only a little part of it failed (because a support dropped off). I want to reprint only that little part. How can I do that in Cura? How can I tell Cura to generate a gcode file so only that little part…
