How to make a classic brass paperboard pulp mold

Posted on November 18, 2021November 18, 2021 by William

When we last contacted the prolific prototype typist [Eric Strebel], he was perfecting the design of environmentally friendly wireless charger and converting its original paper prototype into version 2.0 chipboard considering manufacturing problems. At the end of the second video in this series, [Eric] is printing out early versions of the form, through which he will eventually make a brass screen mold for handling cardboard pulp. You know, some egg boxes are made of what material.
Weld the brass screen into the mold. In the following video, it’s time to build a pulp mold by creating three smaller molds and connecting them to a horizontal mold. The result is a single piece that is then folded into a charging station, much like an egg box. [Eric] uses brass screens here, but he says copper is also a good choice.
After cutting and flattening the brass with scissors, he pressed it into the correct shape using the 3D printing die in the previous video. Each of the three components requires a frame, [Eric] made of more brass wire mesh, then sewed it to the mold with loose wire mesh, and then fixed the joint with solder.
Since the weight of water may bend and deform the brass, [Eric] completed the die by welding on the flat copper strip frame. Take a look at the following great process. Please continue to pay attention to the next video, [Eric] makes some cardboard into pulp and introduces some environmentally friendly chargers.
Does this look too complicated? You can always skip the whole grid mold and directly shape your cardboard confetti into 3D printing parts.
