How is 3D printing done in space?

This article states that 3D printing has been accomplished in outer space, on the International Space Station. I'm curious as to how this works differently from 3D printing on Earth. Are there any extra measures that needed to be taken to ensure…

How important is the minimum layer height on a 3d printer?

I know the minimum layer height will effect how detailed of an item you can print and the amount of time it takes to print something, but is it necessary to have an extremely low minimum layer height if you plan to print only larger objects?

Can 1.75 mm filament be used in a printer that takes 3 mm filament?

As an extension from this question, is there any reason that you would not be able to use 1.75 mm filament in a printer that takes 3mm filament? I know you would have to change the filament size in the slicing of prints but would there be any other…

Using a thermoplastic MDF printer with a 0.4mm extruder nozzle, I frequently have trouble with the nozzle getting clogged. I am not sure what's causing the clog, but my guesses are dust and/or burnt filament (from leaving the hot end on without…

Open Source 3D scanning

I am trying to make a structured light 3D scanner using single camera, light projector and a turntable. After days on Google I did not find any reliable open source project which I can get to work. SLStudio really seemed a good choice but did not…

How to print an overhanging arc

I am designing a part that has to clamp around a 11mm bushing, and due to other design constraints, it has to be printed with a semicircle-shaped overhang: This is proving very challenging to print. Two copies of this part have to clamp tightly…

What can I use to "sand" my ABS prints?

I have a 3d printer that uses ABS filament. The software I use will generate vertical supports for my objects before printing that can be easily broken off after they have been used during print to hold sharp angles up that would normally…

How to automate printing of multiple parts continuously?

I would like to print multiple parts continuously (non-interactively), so I can leave the printer alone for a longer time. So after finish, parts could be moved somehow out from the printing area, so the next can start. Are there any methods of…

Tips for making parts that push/snap together

I would like to make some parts that will fit together. Specifically, I'm making an array of holders for small glass vials, which will stack together vertically to make a kind of extensible spice rack, for a scientific application. Of course, I…

Ideal print bed: Glass or Aluminium?

Glass is always level, easy to clean, easy to work with. Aluminium allows for the addition of automatic bed leveling with an inductive sensor and distributes heat a little more evenly. When printing mostly ABS and PLA, which one is better?

Bed leveling method?

Is there a good method or tool to level the bed of 3D printers? I find myself making small adjustments a lot and it's mostly just trial-and-error. A normal bubble level is of limited help and trying to figure out if the head is the thickness of a…

Uses for PLA scraps

I recently got a 3D printer and have been experimenting with it a lot, resulting in a lot of failed prints (as well as successes, fortunately). I'd like to, if possible, find a way to reuse the material from these failed prints. I am thinking about…

Printed part auto-eject (automatic part removal)

What are the methods to auto eject parts (into a collection area/box/basket) in order for the 3D printer to continue printing? For some reason this feature isn't common (yet?). Is there a hidden reason why? Will using the print head to ram the part…
