more free filament samples

[wolfmanjm]

I have some 1.75 black ABS from atomicfilament.com to give away (actually 1kg, so quite a lot !).

I still have some of the 1.75 PLA left for samples too.

Please let me know if you will be at the meeting tomorrow and want some.

If no one is interested I may skip it this week :)

Thanks

Hi Jim,

Tomorrow we have kids robotics team visiting.  They would love to get some free PLA samples.

Thanks,

Damon

Next week :) I'll probably skip this one tonight.

Has anyone printed with Atomic Filament's ABS yet? I need to buy some black ABS, and would give their filament a try, but their recommended printing temps (230-255 C) goes into a range that'd be hazardous for my ol' j-head. It seems I'm always printing at the low end of such recommendations, sometimes even below them, so I'd probably be OK with the Atomic ABS, but I'd appreciate hearing any experiences you guy's have had with your samples so far.

Thanks,

Pla works good!

[wolfmanjm]

I can bring a sample of the atomicfilament ABS tonight if you are there. You can try it.

I haven't used the ABS but the PLA prints at much lower temps than any of my other filaments.

The website mentions 190 drug C at the low end of the PLA temperature range. I use 185 with my ProtoParadigm and I've been thinking about lowering it to reduce oozing.

What temperatures have you been using with the Atomic PLA?

I printed with the Atomic filament at 195C.  Really liked the Yellow!

I won't make the meeting tonight.

The Perseids meteor shower is tonight.

I will be doing Astronomy.

See you all next meeting.

I had to print Protoparadigm at 200 - 205 otherwise it was brittle and delaminated between layers.

I have been printing the atomicfilament PLA at 185, it is solid and is well stuck to each layer. It does not ooze.

I suspect your temperature readings are reading 10-15° lower than the actual temperature in the meltzone if you think you are printing PP at 185.

I'm sort of derailing the thread, but now I am super curious. I have calibrated my extruder in the past by doing several rounds of auto tuning at 185 degrees with Marlin, ie "M303 E-0 C8 S185"

Any suggestions at getting ground truth? I suppose I can try to aim my IR temperature sensor at the muffler cement holding my extruder thermistor in place. 

Thanks,

Well actually knowing the absolute temp is probably not that important, but if you wanted to you would need to put a thermo couple in the melt zone of the hotend.

I think it is more important to get consistent temperature readings, given the inaccuracy of the thermistors used and the conversions used it is not surprising that the temps are off by around 10° ar the 200° region (betas are only accurate/defined for 25° to 100°)

My test for best extrusion temperature is to print the thin walled _40x20.stl (single wall). If I can pull the layers apart then it was extruded too cold. if it is warped it is too hot :)
