Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[25][5]Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[25][5]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[25][26]Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[25][26]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[27][5]Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[27]
