Multi-Material hinged Roll-Up Box experiment.. TPU / PLA

prusaprinters

<p>I did another experiment with TPU/PLA Multi-Material printing.</p> <p> <figure class="media"> <oembed url="https://youtu.be/FlR2uj_3L2w"></oembed> </figure> </p> <p>I changed the interface section in a way that over a configurable number of layers the 2 materials get kind of "woven" (per layer) to each other (see pic of interface section).</p> <p>This results in a really strong bond between the PLA &amp; TPU that cannot be separated without brute force..</p> <p>Quite happy with the results so far. The flexible hinges work great using this method..</p> <p>This is a prototype of a customizable roll-up box i am working on... just the first test print of the still unfinished design to test the material bond and the flexibility of the TPU hinges...</p> <h3>Print instructions</h3><p>I printed this on a standard MK3 without MMU using a single extruder.<br/> the profile used is my multi color/material profile i wrote about here: <a href="https://schlosshan.eu/blog/2019/03/02/prusa-i3-mk3-real-multicolour-prints-without-mmu/">https://schlosshan.eu/blog/2019/03/02/prusa-i3-mk3-real-multicolour-prints-without-mmu/</a></p> <p>If you want to print the included GCODE, watch out! it is sliced for a non MMU printer and requires 3 manual filament changes (which the printer will ask for automatically).<br/> The order of filaments for this is:<br/> ;Filament Color:: 1 red (start with TPU)<br/> ;Filament Color:: 0 yellow (PLA)<br/> ;Filament Color:: 1 red<br/> ;Filament Color:: 0 yellow</p>
