Talk:Poli Log
So the main plastic we are expirementing is something similar to cellophane? Just Curious. Also could we make a device for extruding sheets of this, or only thin strands? Also what solvent is planned? I have seen Schweizer's Reagent used. Anyways, seems cool and good luck!

Cellophane (cellulose sulfate) is similar to cellulose acetate, sulfate versus acetate functional groups. It seems that the substitutions make the material soluble in common solvents (chloroform) which is the primary benefit (these materials don't seem to melt by heat very well). The solvent may also be recyclable. I think the bulk material will seem similar to other plastics, but a post hydroxylation treatment (to reverse the acetylation) would yield cellulose which could be quite strong. See the Cellulose acetate page and the section on the R&D page: Additive Manufacturing of Cellulosic Materials with Robust Mechanics and Antimicrobial Functionality by Pattinson and Hart (2017) We also need research into the methods of dispersing the cellulose/solvent mixture.

On the 11/9/19 Entry is that ghosting on the cube or no?

itt may be worth doing a print to check for this
Also what settings were used for thee cube + what nozzle? Can we do a print to demonstrate the maximum resolution of the D3D printer
Just wanted to chime in on that, keep up the great work
