In this edition of 30 on 3D, our Senior R&D Engineer, Cameron Williams, explains different fastener options for 3D printed plastics. Most people are familiar with the standard machine screw or multi-purpose wood screw.
Machine screws are a great option for threaded inserts; however, if you don’t have threaded inserts, then you will need to use a screw with coarse threads – like a wood screw.
That being said, there are better options. There are screws specifically designed to go into brittle type or layered type plastic. The thread profile on these screws will help prevent stripping and premature wear of the hole over time. You will be able to thread in and out of the hole multiple times, without issue.
