Here is a fairly detailed look at how much iteration goes into just a tiny part of development.
Did my first few test 3D prints this week. Very excited to keep iterating and testing out what is possible with the printers. Here are some pictures:
The printer has quite a few quirks, there is a chance of warping due to heat that only becomes noticeable about 20% into a model. Hairspray appears to be the industry standard solution to this issue. Another issue that makes building one piece models very difficult is the way the piece needs to be as flat as possible at the bottom (With the next test I will be testing some 45 degree bevels though.) There is also the obvious limitation of this particular method that doesn’t allow for a way to print without a direct support from the base. Meaning horizontal connections and sharp protrusions cannot have open air below them.
After struggling with various desktop and online 3D tools I realized that it would be longer for me to master them then to search for non GUI alternatives. I ended up stumbling onto OpenSCAD and after giving it a try I immediately felt right at home and was able to put together some more precise STL files for printing. OpenSCAD just has two panels, code and render. There are only a few language specific commands, allowing for a very low learning curve if you know some basic programming (Just check out how tiny this complete cheat sheet is.)
With this new tool in tow I was finally able to do some rapid prototyping and ideation with just a bit of code.
I am applying some pointers from the prior model to this one, upping the scale and letting the printer take care of how to hollow out the solid areas. As well as providing a more solid base to combat warping.
I am also working on setting up a well structured Thesis project repository to keep track of all my STL and Design files. ( Already have a Github repository set up but haven’t done much there in a few months now.)
Here it is: DFI-Thesis
Big thanks to the Komodo Lab and Rickee Charbonneau for all the help this week.
