CJP Fullcolor Sandstone

3D Systems VisiJet PXL

Sandstone is one of the few materials capable of full-color 3D prints. It is perfect for figurines, life-like models, avatars, and other products that lend themselves to colorful, high-quality printing.

Additional Info

If your 3D file doesn’t contain any color information, it will result in a slightly off-white/grayish print.

For multicolor, you must either upload a file that already includes the textures (e.g. colored STL, VRML, SKP, X3D, and DAE) or a ZIP file containing all the necessary color information (e.g. an OBJ file with a texture map and an MTL file). Please consult our design guide for more information about textures.

The model needs to be handled with care. Even after reinforcing the model with superglue, the model stays fragile and has problems absorbing shocks.

Take into account that the walls of your model need to be 1.7 to 2 mm thick and the details of imprints can be 0.8 to 1 mm. Long, delicate features like pins, thin fingers, tiny hair points or antennas that are 0.8 to 1.7 mm and stick out might not survive the process.

Exposure to direct sunlight will cause your multicolor model to fade over time.

Moisture will ruin the color of your model.

Skin tone colors and black are difficult to reproduce, so some variation in color will occur.

Min Supported Wall Thickness A supported wall is one connected to other walls on two or more sides.	1.5 mm
Min Unsupported Wall Thickness An unsupported wall is one connected to other walls on less than two sides.	2 mm
Min Supported Wires A wire is a feature whose length is greater than five times its width. A supported wire is connected to walls on both sides.	1.5 mm
Min Unsupported Wires A wire is a feature whose length is greater than five times its width. An unsupported wire is connected to walls on less than two sides.	2 mm
Min Hole Diameter The accuracy of a hole not only depends on the diameter of the hole, but also on the thickness of the wall through which the hole is printed. The thicker the wall section, the less accurate the hole becomes. Through holes must also allow for line-of-sight clearance to ensure all material is cleared during post-processing.	2 mm
Min Embossed Detail A detail is a feature whose length is less than twice its width. The minimum detail is determined by the printer’s resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details that are too small can also be smoothed over in the polishing process. To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.	0.6 mm
Min Engraved Detail A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.	0.6 mm
Min Clearance Clearance is the space between any two parts, walls or wires. To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.	0.9 mm
Min Escape Holes Escape holes allow unbuilt material inside hollow products to be removed. Normally you don’t need to consider this, our technician will add escape holes before printing. When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it.	10 mm
Interlocking/moving or enclosed parts? Sometimes the interlocking/moving parts can’t be printed, since the supports inside the cross section can’t be removed.
Require Support Material? Because each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.	No

Material Spec Sheet

CJP Fullcolor Sandstone is 3D printed using BJ (Binder Jetting) technology.

ColorJet(Binder Jetting) Printing builds up the model from bottom to top, layer by layer.

A roller puts a thin layer of powder on a platform and a print head places tiny drops of glue at specific locations, printing a thin layer of your model. The platform lowers and the roller spreads another layer of powder. The coloring is done by combining 4 different pre-colored types of glue to match the requested color. The surface can have almost any color since the printer prints up to 24-bit colors, equal to 16.7 million different colors.

After the printing process, the model is brittle but is strengthened by putting it into superglue. A UV coating is sprayed on it to prevent decoloration by sunlight.
