3D printers for ceramic clay?

Are there any extruders and printers that do a good job with ceramic clay? I assume the clay has to be fine grained and with enough water added to be able to be pushed out through the extruder's nozzle. I also assume the print speed would have to be…

Resources/methods to construct STL files using disparate parts using OpenSCAD

What resources or methods would OpenSCAD users suggest to piece together disparate STL files? I'd like to take an existing STL model-library of STL parts (head, torso, arms, legs) and make it a Thingiverse OpenSTL maker, similar to the castle…

M4 screw and nut for 3D printing?

Does anyone know where I can get a free 3D design (STEP or STL) of an M4 Screw and nut? I have found only an M3 on Thingiverse: M3 Bolt by Kaleta.

Printing objects with holes using M3D Printer

I am using an M3D printer and loaded an STL design with holes in the middle: However, the output is an object without holes (so I stopped the printing): What can be done to be able to print with holes?

3D printing and coating of heat-resistant objects, such as a turbine blisks or blades

Is it possible to 3D print an axial turbine 2 - 4 inches (50 - 100 mm) in radius, capable withstanding temperatures about 800 - 1000°C and rotation speeds of 100 - 120 x 103 rpm? How expensive is that? Is it cheaper to mill such a turbine from a…

How can I learn to create models for 3D printing?

I've recently bought a 3D printer and waiting for it to be delivered I've given quite a lot of time to looking things up on Thingiverse. I see people create incredible models with gears, screws, lids and a lot of very cool and functional connectors…

Does the amount of figures on the board matter?

When 3D-printing on an 20*20cm, I've heard that the quality of the printings get worse if I fill out the board... Is it true? Should I keep it to small amounts at the time or doesn't it matter?

How to add tolerances/gaps in Autodesk 123D Design?

When I design parts that must fit in each other, I usually keep in mind that prints are 0.2-0.5 mm wider than expected (depending on the material), and I size the parts accordingly. However, sometimes, I design the whole part and then slice it with…

Which is the best 3D printer to print bodies scanned?

I want to print people's bodies scanned (or get 'minimes', see the Figure 1). And I watched that the printer 'project 660' is very good to do this (Figure 1). But, the price of that printer is really expensive, roughly $60'000. And If you want to…
