Can a 3D model of a copyrighted work be rendered legally without infringement?

I know this is still gray territory and it is asked so many times within the 3D printing and maker community but I'm curious about the limits of 3D models and were it touches on Free Use and infringement. I'm not trying to push the envelope, I just…

Maintaining fine details while applying smoothing methods

I've been reading and experimenting with Acetone vapour smoothing on some printed ABS parts. My problem is that I need to selectively smoothen the printed parts which vapor smoothing doesn't allow. In particular, the cogs, whose sides I was trying…

Are there many assembly type 3D printers?

I am wondering if anyone here knows of any 3D printers that work by assembling models from parts instead of extruding or setting material. The closest I have found is the pixelstone but it appears to only be a prototype and I haven't seen or heard…

How to edit Cura profile in Octoprint?

In Cura, I can edit my .ini profile settings as needed, for example, when I change filament or models. It's annoying to have to edit the profile on another computer and update it on my Pi just to change the infill, etc. I've searched…

Infill pattern comparison

I'm relatively new to 3d printing, and wanted to get a few things understood. Firstly, I am unclear on how Hexagonal infill is stronger than, say, diamond pattern. Can anyone explain how the different shape causes the structure to be stronger? I…

What causes gaps in small region fills and how to prevent them?

I saw this cool Nuka-Cola bottle opener. I made it: As you can see, nasty gaps have appeared in the text. What could've caused them? I am sure I set the filament diameter correctly. So why did the Slic3er not generate enough paths here to fill the…

Why does my domed print have a thin shell?

I am making a "fun button", with a dome-shaped top. The vertical sides, top center, and raised lettering seem fine, but the more sloped outer parts of the dome are very thin, with some gaps and the infill pattern is quite visible. It's almost like…

How can I make this rounded enclosure feasible to print?

TL;DR - What needs to be done to the following model to ensure a successful print? As part of a father-son project we're trying to make an enclosure for a digital clock. The idea is to make a 3D printed model of a rocket with a hollow body to hold…

How can I set the position in Pronterface?

I'm in the process of building a 3D printer and have all the stepper motors wired up and the controller connected to the computer running pronterface. I can move each axis and also send g-code to the printer. Now how can I define the current…

Silver Solder specifications for hot end heating element

In this question I was told that I should use silver solder to connect the heating element to the power supply. (I was also told that a ceramic extruder head was the way to go, but I'm working with what I have) I bought two types of silver solider…

What causes these round corners

Nozzle diameter = .4 Extrusion multiplier = 1 Extrusion Width = .45 <-- I feel like this could be reduced to fix it? Layer Height = .3 I'm using Simplify3D.

Can a common 3D printer be used to print masks for PCBs which use SMD components?

Common 3D printers (read "cheap") may be used to print masks for PCBs (printed-circuit boards) which use PTH (through-hole) components. But can they be used to print PCBs which use SMD components? I'd like to make boards at least for Arduino-like…
