Should I use different nozzles for different materials?

I know I should use different nozzles for filaments that use vastly different temperatures but what about filament types that use similar temperatures? For example, PLA and PLA composites like ColorFabb Woodfill filament. Should I use a separate…

Typical plastic strength at 1500 RPM

I'm planning to print a certain sample holder which is going to be placed on a CD-Rom BLDC motor and spun at about 1000-1500 RPM. The holder would essentially be a 2-3 mm thick 100 mm square platform with 1-2 mm thick hooks rising up from outer…

How to create attachable/detachable printed parts

I am making a part that needs to come apart, so I don't want to use glue or similar adhesives. I saw an article about printing snap-fit pieces, but it seems like you would need a lot of expertise to make it work well. Does anybody know of an easy…

What parts are strictly necessary for a 3D printer?

I've built the mechanics of my 3D printer myself, because I need to print parts that are really huge, (and for budget reasons). So, I already have the 3D movement functionality. But what I need now, is the printing mechanism itself. I've been…

How to debond cyanoacrylate glue from pla

I have used cyanoacrylate glue aka superglue to bond PLA. I have created several electronics enclosures. (Definitely the most time-consuming part of the project.) Now my question is which debonder/solvent can I use to separate the pieces again…

What is a good strategy for removing 3d prints from an UNheated Glass bed?

I have a LARGE piece of glass (36"x26") that I will soon be printing on using my newly build MPCNC machine. It is capable of printing about 34"x34"x10". Anyway, I have had GREAT success printing on heated glass that is sprayed lightly with…

What should I think about if I want to design something modular?

For a while now, I have been thinking about designing things such as small bedside tables, game/dvd/bluray racks for 3d printing. I've always thought that making them modular would be a good way to go about doing this as well. Modular design would…

Clean or wipe move for delta 3D printers

I own a delta 3D printer. The problem is that, at the beginning of a print the extruder outputs dirty filament. I want a clean filament flow at the start of my prints! How can I make the hotend exit the print surface (glass plate) by 10mm, extrude…

Does the material a bed is made out of affect the cooling time of a part?

Let's say I print a part out of ABS and wait for it to cool. I could theoretically do this with several copies of the same printer, modified to use print beds of different compositions. Will the material a bed is made out of affect how long it takes…

Marlin menu navigation slow while printing

My Kossel Mini printer (delta) has RAMPS1.4/Arduino Mega electronics configured to use a standard 20x4 LCD display with Marlin during printing. Often, navigating the menus during print can be painfully slow, and I occasionally end up making the…

How to fit a model into a hole with the same shape?

I've 3D printed a box with a hole in it, the hole looks like a horse. My idea was that I then 3D print that horse in a different color and put it into the hole. The problem was that the horse didn't fit the hole, as they were the same size. I then…

How can I optimize my print for casting in metal?

A fellow maker has tried printing a 3D model in clear PLA (<5% infill, 1 or 2 perimeters), burying it most of the way into casting sand, and then pouring molten aluminum. This melts and burns the PLA, and the aluminum takes the space that the…

How can I upload STL files to OctoPrint?

I started playing with OctoPrint and I already have it configured for external access and management, using OctoEverywhere. I would like it to be an easy to use printer, because it is shared between people that don't use Cura or PrusaSlicer, so I…
