Thermal degradation of 3D printed ABS (and other plastics)

The short version of my question is: Are 3D printed parts made of ABS likely to survive for one year in an incubator at 80℃? Please read on for more details. I am printing some parts that will be used inside an incubator in a lab. They are likely…

Nozzle rubs on previous layers

I'm having a frustrating problem with my recent built custom 3D printer so every single print I made, from the third layer, the nozzle is "rubbing" on the already placed filament. This results in a complete mess, melting the previous layers with…

Delta printer distortion

I have make a little test with 4 dots aligned with A tower, B and C tower. Distance W and S are the same in the stl but not in the print. I have tried diferent values of diagonal root but S always is smaller than W, and all S are equal (more or less…

Printing multiple materials with different properties on the same device

I have searched the internet and found various 3D printers with different advantages and materials which they can print - some even multi color. However, I cannot seem to find a printer that can print multiple material with different properties;…

How to use a multimeter to test how many amps RAMPS is pulling?

This is in with my other question about components and the other question about electricity; how can I check to see how many amps are being pulled? Can I check a component at a time to make sure I'm not going over the limit, and then just add them…

When building a RAMPS 1.4 based printer, can I safely plugin just some of the components to test if they are working?

If I need to test out some of the components of a RAMPS 1.4 based 3D Printer, can I only plug some of them into the board (not all of them) and test them out? I'd like to test out the NEMA 17 motors without testing the heated bed or extruder. Is…

Feasible 3D Printed Snap Connectors

I have Ultimaker 2+ 3D Printer and I need to print a piece that doesn't fit within the build volume of the printer. Even though it would fit I'd still need to print it in two parts because I'll need to fit some equipment inside. I could use glue to…

Turning off heatbed for the last few layers. Good idea or not?

My heatbed won't let go off the prints until it considerably cools down. The cooling process takes decent amount of time. I was considering putting the M140 S0 (sets heatbed temp to 0) somewhere near the end of the printing process, so that when the…

How to straighten PTFE tubes?

PTFE tubes are typically delivered coiled up. And because they are quite stiff, they always want to spring back to their original curvy shape, making them harder to route properly. Is there a way to straighten them out?

MakerBot Replicator 1 Voltage Regulator Fix

My Replicator (you know, the one made of balsa wood) has blown a voltage regulator on its MightyBoard for the second time. The first time, MakerBot graciously replaced it. However, they replaced with the same model board with no apparent fix for the…

Levelling heads for dual extruder

I upgraded to a dual Mk9 extruder, and quickly discovered how critical it is to get the ends of both nozzles exactly level with each other -- that is, equally distant from the build plate at all times. Otherwise the lower one will crash against the…

Are self intersecting meshes dirty from a 3D printing perspective?

I have never much cared about self intersecting meshes when slicing with Cura. Geometry like the one below are often practical. I for instance add lots of rivets that self intersect with the base geometry: Now I have switched printer, and am using…

First layer overlap on one side

When printing the first layer, the infill overlaps on just one side of my print. Thereupon there's a rough, and a lot higher, surface on the first few millimeters after the wall. Printer: Arduino Materia 101 Filament: Rec Pla Temp: 210 degrees I…

What resolution (pixels/mm) should I use in SVG for CNC?

I am planning a mechanical 40% keyboard build and are coincidentally on the home stretch of a homemade CNC project. The only thing the CNC needs to do for the keyboard project is to drill 7*48 holes. So what I need to do now is layout those holes in…
