How do PLA, PETG, TPU, ABS and/or nylon work together in a single print?

The answers are yes yes probably Which is to say, if you only want to use MaterialNumberTwo for disposable supports, then you should be fine. Presumably the slicer software is material-aware and ...

What is the best way to adhere an old printed part to the bed?

I have not done this, but I believe this is the best method and I want to test it at some point soon: Model a negative for the footprint of the part you want to adhere to the bed, in the orientation ...

Is the Prometheus system compatible with Wanhao Duplicator i3 Plus?

The Prometheus system is pretty much a Y-coupler and two extruders. So, you need your Wanhao Duplicator i3 Plus to have the connection points for two extruders and the axis, which means you need one ...

Printing multiple materials with different properties on the same device

For the most part, you can achieve this with a dual extruding printer. However, dual extrusion is best for either multi-color printing or printing with support material. For example, printing the part ...

Has anyone encountered this type of strange print patterns?

It is always very difficult to debug a printer remotely, but here's my best shot. I may be totally wrong though! Zooming-in your picture seems to show like little bumps (inwards or outwards) that ...

My first attempt at pausing a print and changing filaments resumed from the wrong position -- how do I troubleshoot?

You are out of luck: Print gcode is written in relative coordinates. If you move the printhead manually, the printer does not know this, and will just follow its relative path from the new position - ...

Cura projecting floating print onto build plate during slicing

I've been playing with this and came up with a solution, so I thought I would share in case anyone else had this issue in the future. In Ultimaker Cura I enabled supports and z-hopping before I sliced ...

What is the best way to adhere an old printed part to the bed?

I like the idea of printing a holder, for the part-it holds the part laterally and indexes the new printing. I would maybe model it and slice it separately. Then model and slice the text as a first ...

What is the best way to adhere an old printed part to the bed?

Adherence is the 3D printer's worst enemy. I use painter's tape, but I heard that you can if you need to remove and re-stick it back, heat the part lightly with a lighter and re-stick it back to the ...

Mixing nozzle vs dual nozzle vs IDEX vs tool changer for pva and pla

I would advise against mixing nozzle - you would have many jams and clogs and you would have to use purge tower which in my opinion is not worth it. Thats scratching point 2. Point 1. and 3. are ...

Through what methods and mechanisms can a multi-material FDM printer operate?

One of the easiest ways that I've seen, which I'm a fan of, is simply putting Y splitters on your Bowden tube and having multiple feeds to a single hot end. The main benefit is that you only need a ...
