Topic: [ABS] MG47 Cycolac

Resin: ABS  Cycolac MG47-BK4500 (Black)
Equipment used: Filastruder #1700s melt filter, full barrrel insulation, vertical mount with Filawinder.  I separated out the motor and heater power so I don't get the inconsistencies due to the motor speed when the heater goes on and off.  Had a bunch of old small form-factor ATX 12v PSUs laying around, so I used that for the motor.
Filament printed on a heavily modifed Mendel Max 2.

DETAILS:
Tip Diameter: 1.6 mm
Extruded temperature: 217°C (my temps have always ran high)
Filament diameter and tolerance: 1.72mm +/- .04
Extruded speed is 7-8ish in/min.
Pre-extrusion processing: Pre-dried it overnight.  Not sure if you need to, but I'm now use to pre-drying everything.
Extruded filament is very smooth and shiny.  Very similar to MG94.
Printing: Printed from layers .2 mm on PEI heated print beds.  Printed speeds vary from 80mm/s.  Beds are heated to 120 degrees, it was stuck pretty solidly even after cool down.  May need to lower this to 100-110.  My other ABS I have to heat the bed to 120 for a solid stick otherwise I get corner warping. 

Printed temperature is from 255. 

COMMENTS:
This stuff was bought as a 20# bag off ebay for $54 ($35+$19 shipping) which is about $2.7/lb.  I'm always looking for the cheapest ABS I can find at the time.  This stuff was black too, which is awesome.  I've been mostly printing pure, because mixing in colorant has usually lead to mostly a heterogenous color.  You really do need to run it through twice for a more solid color. 

The prints (so far) look great!  It is VERY similar to MG94, except it doesn't extrude nearly as fast.  But its a lot cheaper and black.

Pretty standard pellets.

Comparing it to PA746 in the middle and HF380 on the right.

Re: [ABS] MG47 Cycolac

I've spent the past 3-4 days trying to extrude the rest of this stuff.

I'm not sure if I just got lucky with the first 4# of the stuff.  But this plastic is really tough to extrude.  I kept getting blobs that would clog the PTFE tubing in the filawinder every 5-15  mins.  Making it nearly impossible to get another good spool.  Tried varying the temperature and angle of extrusion.  Even took the filastruder apart and bolted everything down tight. 

On a scale of 1-5, this I would rate this as a 2-3 in terms of easy extrusion.  PA746, while smelly as heck, is a 5.
