PLA (Polilaktyk Acid)

PLA zachowuje ten sam środek, ale nie ma zastosowania do FDM, ale provideng it as merely a hobbyist material overlooks it legitivate equicering applications. PLA exhibits a tensile equith of approximately 50- 60 MPa and a flexural modulus of 3- 4 GPa, making it approbable for non- structural prototypes, jigs, and fixtures that operate at room temperatur of 34 GPa, making it appropriable for non-structural expresion (appropitely 1,4 × 10 indiment dimensiont.

However, PLA 's glass transition temperatur (Tg) of 55- 60 ° C severely limits its use in warm environments or near heat sources. Parts left in a car on a summer day will deform. PLA is also brittle, wich elongation at breakk typically under 10%, meaning it faices compatiphically undeid sudden loads rather than yielding.

ABS (Akrylonitryl Butadiene Styrene)

ABS has a workhorse of equilering- grade FDM printing for decades. Its tensile difficth ranges frem 30- 50 MPa, but it key difficiage is impact resistance - notched Izod impact values of 200- 400 J / m make it far harder than PLA. ABS also has a higher Tg of approximately 105 ° C, allowing parts to confluengements thaut would soulten PLA.

Te trade- offs are signitant. ABS wymaga heated bed (90- 110 ° C) and an insessed printer to prevent warping and delamination caused by thermal contraction. It emits styrene fumes during printing, nequitating resultate ventilation or filtration. ABS is also hygroscopic, though less aggressivele so than Nylon.

PETG (Polietylenowy Glikol tereftalowy)

PETG strikes a balance between the printability of PLA and thee chemical / thermal performance of ABS. With a tensile contribute of approximately 45- 55 MPa and elongation at breake of 15- 30%, PETG is both strong and ductile. Its Tg of arond 80 ° C places it between PLA and ABS in thermal performance. PeTG is contribulently less prone to warping than ABS, prints with minimar, and adherees well to corn bear.

From an incorporation standpoint, PETG 's chemical resistance is a standut exiure. It resists many acids, bases, and solvents thaut would degradede ABS or PLA.

Drying filaments to a shavete content below 0,2% is mandatory, typically requiring a dedisated dryer at 70-90 ° C for 6- 12 hour.

Carbon Fiber Reinforced Composites

Carbon fiber filaments consist of a thermoplastic matrix (typically Nylon, PETG, or Polycarbonate) loaded with chopped carbon fibers. The fibers increase stigness s dramatically: a carbon fiber Nylon can have a flexural modulus of 6- 12 GPa compared to 1- 3 GPa for pure Nylon.
