What you ask may be easier than you think. The slicing software is unimportant, generally speaking. Consider especially that your requirements fit the solution spot on. Take a look at this thingiverse snowman. Each of the colors is a separate model. Each of the colors is only one layer thick (0.200 mm). Each of the colors is placed with zero overlap to the ...

Yes and no. for instance simultanious printing of plas plastic and lets say metal. Is such a printer available or in development ? Practically speaking, no. Metal printing requires significantly higher temperatures than plastic, and the two processes are so incompatible that there is currently no good solutions that would allow one printer to print both ...

Let's look at various methods: Multiple Hotends The oldest version and one of the best to print materials at vastly different print temperatures (like printing a cheaper PLA infill into a Polycarbonate shell - the print temperature difference is 60-100 °C) is to have 2 or more hotends. This way also avoids the need for purging towers. It does, however, ...

That is not possible without changing to a different printer main board. The Anet A8 board has 4 integrated (A4988) stepper drivers, one for X, one for Y, one for Z and one for E (extruder 0). Both Z steppers are controlled by a single stepper driver (they are wired in parallel to the single Z stepper driver), there is nothing to free up nor is there to ...

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 adjusts the feed so the layer heights are the same for both materials. BUTbe careful that the support material isn't higher-temp than the object material, or ...

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 you want to adhere it, with just a few mm of height, and clearance suitable for your printer (probably around 0.25 mm) in the XY plane, and print that with thick ...

Yes, but there is no hardened version of the "Diamond" nozzle design. Basically when you want to use a hardened nozzle, or a Ruby nozzle in combination with color mixing (I specifically refer to mixing solutions as the melting chamber is smaller than filament changing solutions and your request for none or minimal purging towers) you need to order a design ...

The first multi material add-on version off J. Prusa includes several separate steppers that load filament into the hot end. Note that selecting an other color will retract the existing filament so that the next filament can be loaded. There is no mixing hotend nozzle. It is therefore working serial, not parallel. Working 2 steppers at the same time will ...

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 free, 4 wire connection slot from a stepper driver. So, let's look what kind of board is in there... This Melzi Hypbrid is the mainboard the Duplicator uses, ...

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 with PLA and all support material with water soluble PVA. In practice, printing two completely different materials is not sound engineering practice as they ...

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 offset the extrusion in the XY plane. The fact the bumps occur on both the X and Y axis, and both inwards and outwards, and that the patterns are not fully ...

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 - which is what commonly is called layer-shifting. To try to mitigate this, there are ways, but they are a little tricky: If your printer has a change filament ...

A Scriptable Process for Generating Multi-Material STL Files: I am now using interactive CAD software to define the more complex features of the object I am printing (in the current case, clock faces), and then using OpenSCAD to do the boolean volume operations. To print the composite object, I need three STL files, one for each material I am using. The ...

You might save yourself a lot of engineering by copying the Prusa MMU2. Here is a github project for someone doing exactly that: https://github.com/cskozlowski/mmu2 If you look on Prusa's web site, you can find printable parts for the MMU2.

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 the part, then I ran this Python function to remove the supports and get the extruder setup. import re def float_part(file): printString = ';LAYER:' ...

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 layer thing. It is important the slicer doesn’t think the text is floating in the air, or it will interpret it as a bridge, and do weird stuff. Don’t use skirt ...

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 bed. Never tried but I'm guessing you would need to cool the bed, heat the part, and stick it back then reheat the bed and continue to print. Glue sticks can ...

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 similar to some extent. With both types you have to align the nozzles in all three axes. Crude aligning should be done by hardware and fine tuning done in software (...

Someone has already studied this: study of electrical properties of 3D printed materials. ABS: dielectric constant about 3. PLA: 2.7-2.9.

I have printed ABS on top of PLA and it has bonded well. It was simple, then "campaign"-style buttons with Prusament Galaxy Black on the bottom and HatchBox white ABS on top. There was no tendency to warp, as I would expect if the ABS were shrinking more than the PLA. I expected this to not work, but I needed white on black and these were the filaments I ...

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 single hot end, so you don't have to worry about extruder offset or alignment or anything like that, but you do have to worry about material blending somewhat. ...

You do not necessarily need a specific design tool, you can use any tool you want to create your multiple material product. It is the slicer software that manages the materials by assigning the correct extruder. E.g. Cura is able to join 2 STL files that fit together and assign each part a specific extruder and thus material. Please read more here for ...

Yes, it can. I have configured it for as many as four extruders. The problem may be in the slicing, as the slicer is responsible for generating the tool change commands. One problem with the Repetier multi-extruder support is that, although the temperature of each extruder is reported by the RepRap firmware response, only the selected extruder is updated, ...
