250 × 380 × 200 mm
X + Y + Z > 10 mm
Your model should be within the minimum and maximum bounding box sizes. The maximum bounding box represents the largest model that our printers can produce. The minimum bounding box size is the smallest dimension in which we can print in this material.
Min Supported Wall Thickness
Min Unsupported Wall Thickness
A supported wall is connected on at least two sides. Walls in your model must meet the minimum measurements to ensure it survives the printing and cleaning process. Thin walls are prone to warping during printing and are fragile to clean. Objects that meet the minimum requirements may still be rejected based on the geometry in which case our production team will communicate with you if the design needs improvements and can assist you to strengthen your model.
Min Supported Wires
Min Unsupported Wires
A geometry is considered a wire when it is thinner in both unconnected directions than its length. Wires that are under our suggested minimums are prone to breaking in the cleaning process.
Min embossed detail
0.4 mm high & wide thick
Min engraved detail
0.4 mm high & wide
We recommend these minimum measurements for details like embossing or engraving, based off of printer resolution.
Single Escape Hole Diameter
Multiple Escape Hole Diameter
10 mm when there are four or more escape holes
When Full Color Sandstone products contain hollow cavities, they are often still filled with powder even after they are removed from the build tray. Small escape holes and difficult geometry can make it impossible to remove excess powder.
A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.
Clearance is the space between an two parts, e.g. space between gears or a ball and socket joint.
INTERLOCKING AND ENCLOSED PARTS ?
Full Color Sandstone products are printed by depositing a binder material onto a bed of gypsum powder, layer by layer. Since the product is solid when it is removed from the print bed, it is possible to make interlocking parts as long as the clearance is greater than the indicated minimum.
Color parts require texture maps. A standard .STL file will not be sufficient for a color part. Color models must be submitted as a single compressed .ZIP file containing a .DAE, .WRL, .X3D, .X3DB, or .X3DV with .PNG, .JPG, or .GIF texture files. If you have uploaded your color model properly, the colors will appear in the 3D render when you select your material and at checkout. If the 3D render is all gray or all black the model will not print in color.
Please note that color files cannot be resized on Shapeways because the texture map will no longer link properly to the model. If you need to adjust the size of the model, please do so on your 3D design software and re-export, zip, and upload your resized model.
Please see this tutorial for additional help creating and exporting files for color printing.
Print Lines or "Stepping"
A "staircase" effect, or print lines, can occur on the surface of your print. These can become more pronounced on curved and angled surfaces
Making your design more stiff (increasing torsional rigidity) will reduce the risk of warping. Longer walls need to be thicker than short ones.
How will the price of my model be calculated?
- Material Volume - the amount of material needed to 3D print your product
- Number of parts - a part is a piece of a model that can be separated from other pieces of the model
- Production - associated production costs including labor; quality control; machine maintenance; general utilities; and other supporting services required to 3D print your product
What is the minimum price per part?
- Natural - $7.50
- Glossy - $11
