Modelling for 3D printing
Minimum wall thickness
Printing material guidelines
Design to avoid or minimize supports
The model must be watertight
STL file resolution
- Low resolution STL file: It is important to note that a poor quality export will never deliver a good print. Low resolution means that the triangles in the STL file are large and the print surface will not be smooth. Like digital images, lower resolutions lead to a “pixelated” print.
- STL file with resolution too high: A file with a high resolution will make the file too large and adds challenges during printing. Since it contains a higher level of detail, it will take a long time to print and some 3D printers may not be able to print it. It is best to try to keep the file size under 15 MB before uploading the model.
Printing technology limitations
Build a solid base
- Enough surface area to create a positive bond to the printer bed. Adding a raft in your printing software application can also help with this.
- A base wide enough to support the model and prevent it from tipping over during the printing process.
- A model base that is strong enough to resist deformation caused by different cooling rates.
