A teacher asked me if it was possible to 3Dprint on leather and that it would stick. The theorie behind this question was that if we can 3Dprint prosthetic directly on the skin of people we may find some benefits of it instead of making the regular prosthetics we know today. So i got a 3.5 mm thick piece of leather and put that in my craftbot+ on the plate where my printbed would normally rest on. then i taped a thermometer on the leather to measure the heat that goes trough the leather. which is if you set the printbed to 110 degrees celsius the leather is 65 degrees celsius. sadly pla did not stick to the leather while printing but tpu98A does stick to the leather. and it is a flexible filament so it flexes a bit with the leather. i printed two objects on the leather. one finished successfully and the other unfinished one was the first test with tpu98A which i canceled to do the other print. after the leather cooled down the prints kept sticking so it works in practice but i have my doubts about 3Dprinting directly on human living skin because the material is 245 degrees Celsius so it will heavily burn your skin. which does not sound so improving to me. also the skin does not have a hard undersurface so the skin is to unstable to print something directly on it. so this idea has potential but there are many hurdes to overkom if people really want to use this method.

-Hoe kun je de eigenschappen van kunststoffen verbeteren? kunststoffen kun je verbeteren door de volgende middelen toe te voegen: kleurstoffen. weekmakers vulstoffen stabilisatoren antioxidanten antistatica -Benoem de verschillende soorten kunststoffen de soorten kunststoffen zijn: thermoplasten thermoharders elastomeren -Benoem enkele eigenschappen van thermoplasten, thermoharders en elastomeren. thermoplasten: plastisch, opnieuw vervormbaar, verslechterd bij langdurige balasting. thermoharders: niet plastisch, word niet zacht bij warmte,bestand tegen hoge temperaturen, ontleed bij te hoge temperatuur elastomeren: niet smeltbaar, elastisch vervormbaar -Benoem thermoplasten, thermoharders en elastomeren die in de praktijk veel worden toegepast en waarom. with solidworks i have drawn a wheel from the conveyor belts from my work. With this wheel i want to experiment if a 3D printed ABS wheel is able to do the work just as well as the original. For this experiment i will look at the wear and tear on the wheels and the rubber bands who are on the wheels. I will also look at at the rate this wheel is able to run. The printed wheel on this image is from PLA so i will not use it for my experiment because PLA is not rigid enough to do the work. This wheel was only printed in PLA to test the design.
