Thanks to larger 3D printers and optimized processes, even large components can now be easily additively manufactured. However, the size of many objects still exceeds the capabilities of most 3D printers. One solution is to divide larger parts into segments and then join them together.
In a YouTube video, the “NeedItMakeIt” channel presents three different joining methods for 3D-printed parts. A dovetail joint, a slotted tenon joint and a traditional screw connection are tested.
The dovetail joint originally comes from timber construction and proves to be superior to the other two variants. The construction finally breaks under a load of 55 kg – but not at the joint itself. This proves to be extremely stable.
According to the YouTuber, the design of the dovetail joint can be optimized even further. Among other things, varying angles and rounded edges could increase the strength. Overall, however, he already rates the first test as a success. Watch the video for an overview of all NeedItMakeIt tests.
