Admittedly it’s a little bit of a distinct segment utility, however for those who want plenty of flat 3D printed objects, one method to go about it’s to print them in a stack and separate them someway. An previous(er) answer is to make use of a non-extruding “ironing” step between every layer, which makes them simpler to tug aside. However one other trick is to make use of the truth that PLA and PETG don’t stick nicely to one another to your benefit. And thus is born multi-material stack printing. (Video, embedded under the break.)
[Jonathan] needs to print out multiples of his enjoyable Multiboard mounting system backplates, and these are the best candidate for stack printing: they’re skinny, however in any other case take up your complete construct plate. As you’d anticipate, the principle trick is to print skinny layers of PETG between the PLA plate layers that you simply do need. He demonstrates you can then merely pull them aside.
There are some methods, although. First is to make two pillars along with the plates, which apparently convinces the slicer to not flatten all of the layers collectively. (We don’t actually perceive why, truthfully, however we don’t use Bambu slicer for multi-materials.) The opposite trick that we anticipate to be extra extensively relevant, is that [Jonathan] extrudes the PETG interlayers just a little thicker than usually. As a result of the PETG overflows the decrease PLA layer, it bodily locks on though it chemically doesn’t. This most likely requires some experimentation.
As multi-material printers get cheaper, we’ve seen much more progressive makes use of for them popping up. And we wouldn’t be so stoked in regards to the matter if there weren’t a wide range of hacker tasks to make it attainable. Most not too long ago, the spectacular system from [Armored_Turtle] has caught our eye. Who is aware of what sort of loopy functions we’ll see sooner or later? Are you doing multi-material but?
