If you want to produce a large number of 3D-printed parts, there are a few things to bear in mind when designing them. In a new video, the YouTube channel “Slant 3D” presents eight rules for optimized series parts.
One of the most important recommendations is to create all wall thicknesses to at least 1 millimeter. This ensures that the nozzle of the FDM 3D printer produces reliable vertical walls. Horizontal overhangs without a support structure should be avoided wherever possible, as they extend the printing time and require post-processing.
The first bottom layer of a print also needs to be well thought out. Complex structures and sharp corners make it difficult to adhere to the printing plate. Round, simple contours are an advantage here. As a general rule, corners and edges on the 3D model should be rounded off, both for a more appealing design and for smoother movement of the print nozzle.
Other tips include avoiding cavities inside the parts and choosing thick-walled, solid structures instead. It is also advisable to keep the contact surface with the printing plate small so that the finished objects can be removed more easily.
