Have been experimenting with 3D printed parts for D3D using a Rostock printer, ABS plastic, and Repetier to generate g-code. ABS is warping away from the bed, and optimization has included raising the bed temperature, decreasing the printing speed, and printing on a bed lined with painters tape. In order to optimize prints had to generate axis pieces stl files and mirror part.

Started receiving ordered materials. Preparing to print necessary parts in ABS on Rostock printer. Investigating 16' frames considering steel, PVC or acrylic, leaning towards steel.

Have been researching D3D printer and how to solvent cast 3D print set-up documentation site for a replication build. Dispersion of solvent disssolved material require fluid pumping to drive extrusion.

Installed freecad. Focusing research on cellulose based 3D printable materials because this seems to be the most boot-strappable material to manufacture in the OSE context. Printable cellulose requires solvents for dispersion rather than using thermal melting.

After a long hiatus the OSE bioplastic project is back under development. Background research is near completion and current work is to design and build prototypes of a chemical reactor capable of producing PLA (and PE).

Where to pick up again?: 1. Determine the necessary capabilities of a reactor for producing bioplastics. 2. Make reactor core schematics and determine manufacturing techniques. 3. Build a budget for reactor prototype and substrates. 4. Crowdfund necessary funds. 5. Build prototypes at FeF in Summer 2019.
