It’s been a long weekend, and while trying to relax I’ve been thinking about the next steps in this process. During testing, the most apparent issue was the rigidity of the molder’s stand. As you can see in my previous posts, the stand was made of poorly cut 1″x1″ lumber mended together with steel brackets. …
Today was a pretty big day. Although I only started building this prototype about a week ago, this idea is a long time in the making. Over this past winter, I tried something similar and achieved nothing but burnt plastic and some softened plastic that stuck together and was extremely brittle. That was the crude …
Despite still being quite crude at the moment, the prototype injection barrel has been attached to the frame and the plunger lapped to it. We are getting close to melting some plastic! Next up is the nozzle, these are often highly engineered components that are meant to flow lots of plastic with little resistance. Mating …
The idea for this project came from the need to quickly manufacture plastic prototypes and products. While 3D printing has become highly accessible forsingle pieces and rapid prototyping, the speed and quality of these prints isoften not satisfactory. Injection molding has always been relegated to large scale industrialmachines which can cost thousands of dollars. Even entry …
This website is meant to track, showcase, and offer products that I have developed.
