How to test new filament on a Taz
| By Michigan Tech's Open Sustainability Technology Lab.
Wanted: Students to make a distributed future with solar-powered open-source 3-D printing.
- Same as Taz 6 use
Equipment or Bill of Materials
- Lulzbot taz 6
Note: 9.11 kWh/kg for PETG
specs: nozzle temp = 235C bed temp = 65C print speed 60 mm/sec and with 100% infill
Operation & Procedure
- Before you start to get an idea of what you need to do for finding the right print settings - read this carefully - Woern, A.L.; Byard, D.J.; Oakley, R.B.; Fiedler, M.J.; Snabes, S.L.; Pearce, J.M. Fused Particle Fabrication 3-D Printing: Recycled Materials’ Optimization and Mechanical Properties. Materials 2018, 11, 1413. doi: https://doi.org/10.3390/ma11081413
- Do a mini lit /web search to find the default settings for your base plastic as a rough guess on temp -along with your recyclebot experience.
- Ensure that your filament is thin enough to fit into the filament hole on the Taz.
- Take out the old filament and put your filament in the hole. Look for a minimum temperature that it will extrude out manually by adjusting the temperature on Lulzbot with the dial and pushing it with your hand through hot end. At the "right" temp - you will see the plastic come out of the nozzle - the exact width of the nozzle hole (e.g. no thin, weird curling, etc.)
- For speed start with some of the default settings under the advanced menu in Lulzbot Cura for the same/similar base polymer.
- Make the following prints using the STLs in this project (https://osf.io/f4rh9/ ):
- line/liness to get right T and speed
- vase - test wall thickness with calipers
- cube - test x, y, z with calipers
- 5X ASTM D638 Type 4 standard tensile bars.
