The Dimensional Print Studio has joined the ranks of multi-color three-dimensional printing. This is with the FDM (Fused Deposition Modeling) process using plastic extruded filament. The printer obtained, a GeeeTech A20M (the “M” is for multicolor) printer.
The A20M uses two filaments and combines the feeds into a single nozzle. This permits blending (sort of) of the two filaments. The colors don’t mix and when fed to the nozzle together, come out the 0.04MM tip side by side in proportion to the feed. Like stripe toothpaste in a tube. 30/70, 50/50, 70/30 it will show in the print.
Much two-color printing is done with a nozzle for each color. No blending is possible. Using a single nozzle, requires a purge area to pump out the old color before printing (100%) with the new color. A “purge pillar” is built up layer by layer alongside the intended print for purging. This pillar is “wasted” and thrown away and is a concern for some stingy printer owners.
Two color printing can take up to twice as long as single color printing. So, two color printing is not popular for many folks. Especially if they have an extreme obsession or phobia about “wasting” material changing colors.
Waste is a product of all forms of crafting and manufacturing. Does a woodcarver obsess over the 50% waste of material in the form of shavings and chips when carving a figure? Did Michael Angelo obsess over the “wasted marble” when carving David? I think NOT!
Not sorry about the rant above. I’ve just heard about wasting material too many times in 3D printing…
The rewards of having color options are quite enjoyable. For me it has moved my printing further in the realm of an art form, without the need for priming and painting. Or printing multiple pieces to assemble. That will go on, but it is fun to design and see it produced in a single print.
Here are some examples of my first prints. Surely there will be much more to come.
