Files submitted for print can sometimes be rejected because they present features that are too thin. Below we list a few instances in which this is true:
- Features have a thickness of less than 2mm: models sometimes include sections that stick out or stand away from the main body (antennas on a bug, columns as part of a building, window frames, bridges, etc). These features need to be at least 2mm thick (we recommend going above 2mm) for them to have a better chance of printing.
- Small features are in areas that need Support Material: if small details are encased in supports, it is very likely these small features will be confused with the supports and be accidentally removed during cleanup.
- Parts are too thin to endure cleanup: cleaning up models includes taking them off the printing plate, removing support material, and cutting away any debris left from printing. All of these processes require placing some force on the piece; if the part is too thin or delicate, sections of it can easily break or peel off. Make sure your model is watertight.
- Walls are too thin: if your model has any walls that are thinner than 2mm, the part is bound to be rejected or fail. Walls that are thinner than 2mm are hard to identify by our printers and you often end up with a hole in the piece. If the wall does make it through printing, it often breaks during cleanup due to how delicate it is.
Always keep in mind that the thicker you can make a part, feature, detail, or wall, the better chances it has to print successfully. Never go below 2mm, avoid pointy parts facing down and ending in a peak that is less than 2mm thick, add thickness to long skinny sections, and always let us know if you have doubts!!
