This is really cool, could you post photos of your results so far and the sources for your procedure? This book recommends a freeze drying/salt leaching method specifically for PCL. Scaffolding in Tissue Engineeringby ironchief - Tissue Engineering
I'm using the standard hot end with the Makerbot Replicator Dual which looks like this. I believe they call it the Stepstruder MK8. The hot end in this extruder is looks pretty short, though I don't have any specs to compare it to. Here's the list of techniques I'll try next week - dry filament - dry ice - filament guide - prestress? (looking for information on how this works and how to do itby ironchief - General
I'm using 1.75mm filament and yes there is a gap after the drive gear which I've ordered some parts to fill. When the parts get in I'll update. Using 3mm filament might be a good idea, but I'm not sure how to retrofit my Makerbot Replicator Dual for that.by ironchief - General
Hi all, TLDR; 0.2mm nozzles with PVA is hard, I'm increasing the modulus of elasticity by reducing the filament temperature (dry ice, freezer) as well as experimenting with extruder designs Long version: Problem: I've been printing with PVA with 0.4 mm nozzles with some success around 185 C. I'm looking to switch to a smaller nozzle since I'm creating single strand PVA bridges (for vascular syby ironchief - General
