I recently came across this industrial grade meet grinder. Its located in a laboratory used for, among other things, injection moulding. I’m told that its used to grind plastic granules down into a fine powder. What is particularly interesting though is … Continue reading
Generally speaking, plastics (polymers) are thought of as quite stable when compared to other naturally produced materials as they do not rust, rot or otherwise degrade in the traditional ways. However plastics do have their own set of weaknesses which, … Continue reading
More of the same ‘out loud’ thinking on the issue of warping in this post to follow on from the last post on warping fundamentals. In particular, thinking about how the speed of a print, the size of an object and … Continue reading
The cause of warping may be an obvious phenomena to some, but for myself it is far from it. However, having now had some time to chew it over I now feel like I have a much better handle on … Continue reading
Here is an interesting little experiment you can do at home with the kids. Take some plastic food wrap, and tear off a rectangle section thats around 5cm (2″) wide and as long as the box. Try to get an even tear. … Continue reading
From it’s heated print bed to it’s heated extruder, a reprap is hot property. So having a sound understanding of what heat is and how this heat is transferred to other materials may help you in building better reprap related paraphernalia. So consider … Continue reading
Reading back over my original post on adhesive principles I think I have may made it overly complicated. So consider this the key points from the first post. Having a good understanding of the principles behind how hot extruded plastic … Continue reading
