Hi,

I was wondering if is possible to create PLA filament at home. And if yes where could I find formulas and instructions to do so.

Thx,

i think the hard part would be to keep the filament width constant at home.

I seem to remember seeing a video where Adrian Bowyer said that creating PLA yourself would be tricky because for part of the process it has have the water content content seriously reduced ... and not simply air dried, but chemically (or mechanically?) treated.

Does anyone have any idea how much PLA weighs per 100mm or an equivalent, save me cutting up a new roll? As I see SF40 gives me a weight of a printed object and I would like to know how much PLA has been used in a length measurement so that I can cost out my prints.

100m of 2.9mm filament weighs 0.9 kg:

So by my dodgy calculations 1mm should weigh 0.000009g. Real brain fade here I printed an object that according to SF and my scales is 2.2g

0.000009kg /mm not g

Each 11mm length of 3mm filament should weigh 1 gram.

I think Skeinforge reports the length of extrudate rather than input filament.

Skeinforge does produce a materials cost and machine time cost per printed part.

I am not sure where the setting is - I will check tonight but I think it might be under statistics somewhere. You enter cost per kg.

The statistics module is available under "Analyze". I've attached a screenshot if it helps.

Just had a play with the statistics numbers and I think I have a realistic idea of how much each print costs now. Thanks, its more so that I can track how much I am spending as I have to budget for the PLA since I can't work at the moment
