Anyone familiar with resin 3D printing knows that the color choice of resin materials is very limited, unlike the rich colors of FDM wires. For example, Formlabs resins are only available in four colors: transparent, gray, black, and white. One of the possible reasons for the lack of color is that coloring can potentially affect print quality because the UV curing laser must partially pass through the resin.
But now, MakerJuiceLabs, a third-party 3D printing resin manufacturer, offers an interesting coloring solution. The company offers a range of pigments, currently available in black, blue, green, yellow, red and white. Customers can selectively add it to the resin, so that the resin becomes the corresponding color. You can decide the amount of addition according to the degree of coloring you want.
Although MakerJuice did not say so, it is speculated that different pigments can also be mixed, for example, by mixing red and blue pigments to form purple. And this is what the resin maker is doing: create a variety of new colors with different pigment combinations.
It should be noted that coloring should not be allowed to affect print quality. In fact, MakerJuiceLabs said: "It is best not to color the resin material of Form1 / + printers. These resins are precisely designed and used specifically for these printers. Any additional coloring will cause printing problems." However, try new colors There is nothing wrong with it, and printing failure once or twice may be the price you have to pay to find accurate colors.
Pigments are actually quite cheap, and a small bottle of pigment that can color 10 liters of resin costs only $ 8 to $ 12. In other words, about one dollar per liter. Is it very affordable?
Now, many 3D printer companies have adopted an open materials strategy. For this situation, the coloring method of MakerJuiceLabs is an interesting and suitable addition.
