| Min Supported Wall Thickness|
A supported wall is one connected to other walls on two or more sides.
| Min Unsupported Wall Thickness|
An unsupported wall is one connected to other walls on less than two sides.
| 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.
| 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.
| 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.
| Min Engraved Detail|
A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.
| 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.
| 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.
| 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.

Material Spec Sheet
SLA PP-like Resin (Somos 128) is 3D printed using DLP/SLA (Digital Light Processing/Stereolithography) technology.
Stereolithography is used to build your design with this material.Starting from a 3D model, a model is built by cutting it into thin layers via specialized software.
A support structure is created, where needed, in order to deal with overhangs and cavities.
The process takes place in a large tank and begins when a layer of liquid polymer is spread over a platform. This machine then uses a computer controlled laser to draw the first layer onto the surface of a liquid polymer, which hardens where struck by the laser. The model is then lowered and the next layer is then drawn directly on top of the previous one. This is repeated until the model is finished. In this way, layer by layer, an object is “drawn” in the liquid by the beam, with the layers being consolidated throughout the process.
When the object is complete, it is raised out of the tank via the supporting platform – much like a submarine rising to the surface of the water – with the excess liquid flowing away. The supports are removed manually after the model is taken from the machine.
