Beyond the Blueprint: Creating a Galaxy - Post 4-3d Printing - Possible Progress

A successful 3 D print with the resin PLA…

The continued saga of building a telescope...the 3D printing phase. So here is what we have learned so far. It is all about chemistry. Before you “click” to close this page, I will provide the short and quick version. PETG is a filament and acts like a sponge that chemically soaks up water. Substances that absorb water expand. Expansion means it gets stuck in the nozzle and does not print. So....first we have to dry it out and then put it in a "dryer" that feeds it to the printer. The picture above is a part made with the PLA resin. We know the files are good...it is just a matter of getting it dry and finding a printer not in use. This is what took a week to figure out. It is true that “slow and steady” wins the race. So the story goes....
