Diary of a Technocratic Anarchist

This ought to keep everyone laughing at my expense for a week. Have fun and welcome to it! :-D I built the JDM PIC chip programming board m...

Brett has kindly agreed to knock out a few kits for version 2 of the filament extruder and made some very valuable contributions towards its...

After having removed the auger and cleaned it I left the extruder barrel heater on at 120 Celsius to cook out the rest of the polymer out of...

I removed the auger from the extruder again prior to setting up for a new extrusion test, this time with a heated quenching bath. Polymer m...

Solvay lists the melting point of CAPA at 58-60 Celsius. I created a water bath of that temperature on my stove and dumped in the filament ...

Reviewing the on-line literature about producing monofilament it would appear that for CAPA and polymorph at least we could use a heated que...

I realised late this afternoon that I need not build a framework as such to hold the quarter-inch extruder vertical. Ten minutes with a fe...

I disassembled the polymer extruder for the first time since it was assembled and tests began. As usual the auger, whose extreme end resides...

07:45 PDT AKA 16:45 ZULU TIME 8 March... This morning I did another test run of the extruder, this time with the barrel temperature set to ...

20:45 PDT AKA 04:45 ZULU TIME 8 March... Not to put too fine a point on it, the upgraded Mk II concept filament extruder... extrudes filame...

After reviewing Vik and Brett's comments, I decided to see if I could pump polymer through a PTFE barrel with an auger bit. It turns ou...

I decided to run a few preliminary tests on the 6.35 mm filament extruder before I did further work on it. I used semolina as a proxy for p...

The weather held this weekend so I was able to almost finish the 6.35 mm filament extruder prototype. I am using Adrian's size convent...

I put in a few hours using AoI to see if I could make all the pieces for the quarter inch filament extruder work together. I'd like you...
