Whereas FDM printers have gotten greater currently, there’s nearly at all times going to be an element that’s greater than your mattress. The reply? Break your design into components and assemble them after printing. Nevertheless, the precise technique to do this can be a little bit of a private alternative. A mechanical engineering scholar wrote:

After researching the state-of-the-art in addition to your concepts right here on reddit, I spotted, that there are nearly no common approaches to divide a big half and be part of the items which preserve mechanical energy, exactly place every phase, and in addition counteract tolerances as a result of FDM-process.

Subsequently I attempted to develop a common technique to phase massive trim components, additively manufacture every phase and eventually be part of these segments to kind the specified general half.

The result’s a research paper you’ll be able to obtain without cost. The tactic focuses on skinny components supposed as automotive trim, however may most likely be utilized to different instances.

You possibly can learn concerning the thought course of, however the remaining consequence was a joggle — a joint made with a rabbet and tongue. Adhesive holds it collectively, however the joint gives benefits in constraining the ultimate product and the transmission of drive within the meeting. Judging by the image, the method works properly. It will be attention-grabbing to see slicer software program develop the aptitude to phase a big mannequin utilizing this or the same method.

In fact, you’ll be able to simply build a bigger printer, not less than to some extent. It appears, although, that that time is pretty big.
