What is stopping us from mixing 3D filament colors in an Extruder?

I just started with google and phrase "3d printing color mixing" and on the first place (in fact first two were valueless adverts) I got this Instructables - DIY Full Color Mixing 3D Printer. How it ...

Could nail polish damage pure PLA?

This is an ugly question, and an ugly answer. Nail polish doesn't come with an ingredient list. Nor are there MSDS's available to refer to what solvents are in it. So it's "unknown 1" Most every ...

What is stopping us from mixing 3D filament colors in an Extruder?

The three in one print head is the closest to your concept of gradient printing and does some nice transitions. But does not meet your color mixing. Which I assume your looking for there is ...

What causes a print to be more or less "shiny"?

In short, PLA filament is somewhat hydrophilic. When you first unwrapped your reel of filament, it can be safely assumed that it came from the supplier nice and dry (unless you have a dodgy supplier). ...

What is the best color of PETg to use for outdoor durability?

Unless you plan to use your copter outside Earth atmosphere or expected lifetime is more than tenths of years, UV degradation should not be a problem for PETG. Some of the net sources indicate the ...

What is stopping us from mixing 3D filament colors in an Extruder?

Branching off of TomvanderZanden's answer, this process cannot easily be done with an extruder alone. To properly color polymers, a pigment must be added during the initial treatment process (...

What is stopping us from mixing 3D filament colors in an Extruder?

As darth_pixel points out, people have had limited success with feeding multiple colors into a diamond hotend and mixing them, but I would argue this is not truly what you're looking for. The problem ...

Methods for applying full color graphic decals to the surface of a 3d printed part?

Industry has for years used a 'pad printer' to put images on complex shapes, like plastic or ceramic travel mugs, etc. I have observed these, but never used one. I see no reason why there couldn't ...

Does color changing PLA require a hardened nozzle?

The color changing material used in the filament is most likely a Leuco dye. There are several types and some can be abrasive (just like the glow in the dark dyes); but, they aren't like putting sand ...

Could nail polish damage pure PLA?

Nail polish will not damage your PLA model. 1) Let's talk about "gel" nail polish. Gel polish self-levels, does not drip, is cheap, is much more health-friendly than many finishing methods, and only ...

What actual dyes are used in filaments?

No Dyes at all. Your question is based on a misconception: A dye is a coloured substance that chemically bonds to the substrate to which it is being applied, this distinguishes dyes from pigments ...

What actual dyes are used in filaments?

I spoke with a chemist tonight. He said to start with the SDS (or MSDS) for the filament, which is required to be available for most materials. It should list the pigments and additives if they ...

Dye sublimation printing on 3D printed object

Yes, ABS can be dye sublimated quite easily using a press, timing is the main issue. PLA can also be dye sublimated if you're careful but will lose a lot of volume due to the heat and pressure. Not ...

true color printing with CMYK+White (not 3-in-1 diamond head RGB)

You may be a bit misled here. First of all, you do not want "RGB" , as those are additive colors such as used when combining light sources. You do want "RYB" (red-yellow-blue) or the more accurate ...

How are SLS printers able to print multiple colours?

The Z-corp/3D systems printers lay down what is essentially ink in each layer (only around the perimeters) much like an inkjet printer, dying the powder as the parts are made. This means they can make ...

I would not expect a problem. The greatest problem I would expect would be if the PLA layers were not well bonded, and the coating material could work in between layers. If so, over time the ...

Why isn't any color showing up in my .3mf file in Windows 10 3D Builder
