Chemical-Resistant PPSU 3D Printer Filaments

Off-White

Fabricate custom bottles, packaging, and other parts for chemical processing. Made of PPSU, these filaments won’t break down even after prolonged exposure to virtually any acid, base, or solvent. They also stand up to oil and fuel, so they’re sometimes made into automotive parts. Because they have a low density and won’t transfer electricity, they make parts that are lightweight and protect components from electric currents. These filaments are easy to store too, since they resist absorbing water. Rated UL 94 V-0, they meet flammability standards.

Print these filaments on a fused filament fabrication (FFF) 3D printer. Due to its high melting point, PPSU is more difficult to print than most other materials. You need an all-metal extruder and a heated printer bed to reach its minimum printing temperature. After printing, anneal your part in an oven for 2 to 4 hours to reach its maximum strength, temperature, and ability to resist chemicals.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your part will start to lose structural integrity.

Tensile Strength—Tensile strength is the best measure of a filament's overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it's the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.

Flexible TPU 3D Printer Filaments


Black	Blue

Green	Orange

Red	Silver

White	Yellow

Stretchy, soft, and sturdy, these filaments make durable parts that resist breakage despite repeated use. Stronger than ABS and PLA filaments, they create long-lasting parts, such as seals, sleeves, and gaskets, as well as components that take on high-impact forces, such as springs and snap-fit parts. These filaments don't require a heated printer bed, and they won't shrink or warp when cooling. Use them with a fused filament fabrication (FFF) 3D printer. In general, these flexible filaments require a slow feed rate so they don't jam. The softer your filament, the slower your feed rate will need to be. Store them in a sealed container with a desiccant, or use a dehumidifying cabinet, since ambient humidity will cause the plastic to degrade and weaken.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.

Durometer 85A—For the most flexible parts, use durometer 85A filaments. They're more flexible than other TPU filaments.

Durometer 95A—For a quick print without sacrificing flexibility, choose durometer 95A filaments. They print much faster than other TPU filaments.

Moisture-Resistant Polyester 3D Printer Filaments

Black

Clear

Parts printed with these polyester filaments absorb less moisture than other types of plastic, making them ideal for use in wet or humid environments. They are more durable and flexible than PLA, and easier to print than ABS. Use these filaments with fused filament fabrication (FFF) 3D printers, and print onto a heated print bed. Printing onto a cool surface causes the molten filament to change temperature rapidly, which can warp your designs. Although finished parts are moisture-resistant, these filaments are sensitive to humidity, and should be stored in a dehumidifying cabinet or a sealed container with desiccant for the best printing quality.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.

Carbon Fiber Filled—Carbon-fiber-filled PETG is often used to make rigid parts that are difficult to bend and break. Finished parts are easier to thread and machine than unfilled parts. Because these filaments are abrasive, use them only with abrasion-resistant nozzles.

PETG—PETG contains glycol, so it is less brittle and easier to print than PETT and PCTG.

PCTG—PCTG is more impact resistant than PETG and holds up to a wide range of acids and bases without breaking down. It is often used for printing parts that will be exposed to chemicals and oils.

Static Dissipative—Static-dissipative filaments make parts that protect equipment from electrostatic shocks by diverting electrostatic discharges in a controlled way. Create tool handles, tote trays, enclosures, and other parts that are used near sensitive electronics. To adjust the surface resistivity of your printed part, change the temperature of your printer’s extruder. As the extruder’s temperature increases, the printed part’s resistivity will decrease.

Antistatic—Antistatic filaments make parts that prevent the buildup of static electricity. This helps prevent the buildup of dust or fibers on the surface of your finished part. However, they are not as effective at preventing electrostatic discharge as static-dissipative filaments.

Impact-Resistant ABS 3D Printer Filaments


	Black

Bumps, scrapes, and falls won’t damage these tough ABS filaments. Known for their durability, they absorb impact without cracking or breaking, and won’t degrade when heated. Use them to print tool handles, storage cases, and other parts that are handled or dropped frequently. These filaments are a good place to start if you’re experimenting with printing impact-resistant parts.

Use with a fused filament fabrication (FFF) 3D printer. These filaments have a high melting point and must be printed onto a heated bed. Without it, parts will cool too quickly and warp. These filaments also release fumes as they are printed, so use an enclosed printer or a fume exhauster to ventilate them.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.

UL 94 V-0—Filaments rated UL 94 V-0 meet strict flammability standards. Use them to create holders, guards, housings, and other parts that protect sensitive, flammable equipment and machinery.

Static Dissipative—Static-dissipative filaments make parts that protect equipment from electrostatic shocks by diverting electrostatic discharges in a controlled way. Use them to create tool handles, tote trays, enclosures, and other parts that are used near sensitive electronics. To adjust the surface resistivity of your printed part, change the temperature of your printer’s extruder. As the extruder’s temperature increases, the printed part’s resistivity will decrease.

High-Temperature PEI 3D Printer Filaments


	Beige

Often used to make parts that will be used near ovens, engines, and other hot machinery, these PEI filaments remain strong and rigid in temperatures that would soften most plastic. They’re a lightweight alternative to machined metal parts. Print these filaments on a fused filament fabrication (FFF) 3D printer. Because of their high melting points, you'll need an all-metal extruder and heated printer bed to reach their minimum printing temperature. Without the heated printer bed, parts will cool too quickly and warp.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your part will start to lose structural integrity.

High-Strength Impact-Resistant Polycarbonate 3D Printer Filaments

Create strong, durable parts that carry heavy loads and absorb blows and other impact without cracking or breaking. Made of polycarbonate, these filaments are stronger and resist heat better than other impact-resistant filaments, such as those made from ABS or ASA.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.

Static Dissipative—Static-dissipative filaments make parts that protect equipment from electrostatic shocks by diverting electrostatic discharges in a controlled way.
