Filament

The filament is the most important factor of the printing process, therefore you

want it to be:

•

Precise: real diameter (2,85mm or 2,95mm) must be as constant as

possible, and within the usual tolerance (+/- 0,1mm) or stricter (+/- 0,05).

Remember: use a good caliper (nowadays, there are good digital calipers

that are quite cheap) to measure the diameter to pass to the slicing app.

Homogeneous: no foreign particles have to be inside the filament (metal

•

powder, carbonized fragments, wood pieces) to avoid extruder nozzle jam

•

Dry: some polymer (i.e.: polyamides, PVAs) absorb humidity, making for

degraded prints or even destroying the filament (PVA). Keep your spools

into dry containers, use dehydration media (silica gel, molecular sieves, ...)

to keep as dry as possible the environment. Two hours at 70°C into a

standard kitchen oven may help to greatly reduce the trapped humidity.

DON'T uses microwave ovens, unless you can really set power at

VERY LOW levels: you can easily melt the spool, with possible

dangerous fumes developing !
