2.85mm Wire | McMaster-Carr

These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Easy-to-Print PLA 3D Printer Filaments


Black	Blue	Gray	Green	Orange
Red	White	Yellow	Clear	Beige

The most commonly used 3D printing material, these PLA filaments make detailed parts at a low melting point, so they won’t warp as they cool, rarely clog nozzles, and don’t require a heated printer bed. They’re also unlikely to drip and produce plastic strings for a clean finished part. In general, they’re best for printing prototypes instead of load-bearing parts since they’re not as strong as ABS or as heat resistant as PEEK. Print them on a fused filament fabrication (FFF) 3D printer.

Carbon fiber-filled PLA filaments make rigid parts that are difficult to bend and break. Their parts can also be threaded and machined more easily than the same non-filled filaments. Because these filaments are abrasive, you should only use them with abrasion-resistant nozzles.

Stainless steel-, iron-, copper-, and brass-filled PLA filaments are heavier and transfer heat better than plastic-only filaments. Brush, sand, or polish printed parts for a metallic finish. Stainless steel and iron are abrasive, so use them with abrasion-resistant nozzles only. Iron will also rust if exposed to water.

Wood-like PLA filaments mimic wood without actual wood powder, and exhibit similar density and appearance to wood. You can sand, paint, and stain your part.

Static-dissipative PLA filaments make parts that protect equipment from electrostatic shocks by diverting electrostatic discharges in a controlled way. They’re often used 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.

Conductive PLA filaments are best for creating circuit prototypes and other conductive pathways. 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.

Filaments with an annealing temperature can be heat treated to make parts harder, stronger, and better at resisting heat. To anneal, heat your finished part to the listed temperature and then let it cool slowly.

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.

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. Filaments that can be annealed are also rated for maximum temperature after annealing, which is the new maximum exposure temperature once that process completes.

Wear-Resistant Nylon 3D Printer Filaments

Black

Off-White

Gray

Print tough, long-lasting parts that won’t scratch or wear out from constant motion and friction, such as gears and washers. You can even tap or drill the parts without them cracking or shattering.

Use these filaments with fused filament fabrication (FFF) printers. Because of their relatively high melting point, a heated printer bed is recommended. These filaments also emit fumes when printing, so it’s best to use them in an enclosed printer or to remove the fumes with a fume exhauster. Store them in a sealed container with a desiccant so they don’t absorb moisture in the air, which can make them unusable.

Nylon 6/69 filaments stand up to chemicals for use in a variety of chemical processing applications. They’re also FDA Compliant 21 CFR 177.1395 and FDA Compliant 21 CFR 177.1500, so they can be used to produce parts that are intended for processing, handling, and packaging food and beverages.

Fiberglass-filled nylon filaments make strong parts that are less prone to warping or shrinking than the same filaments without any filler. However, they’re abrasive, so only use them with abrasion-resistant nozzles.

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.

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.

Slippery Wear-Resistant 3D Printer Filaments


	Beige
	White

Often used to make bearings, worm gears, and other smooth moving parts, these filaments create parts that won’t wear out from constant motion. They're a slippery thermoplastic blend, so they have better wear resistance and lower friction than other filaments.

Print these filaments on a fused filament fabrication (FFF) printer. Because of their high melting point, a heated printer bed is recommended since the parts will cool too quickly and warp without it. You must use an enclosed printer or fume exhauster while printing these filaments. Store them in a sealed container with a desiccant, or use a dehumidifying cabinet, since moisture in the air can degrade their 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.

Flexible TPU 3D Printer Filaments

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.

Conductive filaments can be used to create circuit prototypes and other conductive pathways. You can adjust the surface resistivity by changing the temperature of your printer's extruder. As the extruder’s temperature increases, the printed part’s resistivity will decrease.

For the most flexible parts, use durometer 85A filaments. They're more flexible than other TPU filaments. For a quick print without sacrificing flexibility, choose durometer 95A filaments. They print much faster than other TPU filaments.

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.

Structural Support 3D Printer Filaments

Print structural support along
with your part to prevent the
part from losing its shape

Amber

Off-White

White

When 3D printing a model with overhangs or hollow spaces, use these filaments to prevent the model from losing its shape. They support the structure during the printing and cooling process, then dissolve or snap away once the part is hardened. Use them in dual-extrusion fused filament fabrication (FFF) printers alongside your primary filament. Unlike parts with supports printed from a single filament, there’s no cutting, sanding, or polishing required.

Choose a filament that has similar printing requirements as your primary filament. You will want to choose a support filament that prints at a similar temperature as your primary filament and has the same requirements for a heated build chamber, so they cool at the same rate and won’t warp. Aquasys 120 filaments are compatible with the widest variety of filament materials, but they require a heated build chamber. Aquasys GP filaments are good at supporting heat-sensitive materials, such as PLA and PET, because they print well at lower temperatures and don’t need a heated build chamber. Aquasys 180 filaments work with high-temperature plastic, such as PEEK, PEI, and PPS. They require a heated build chamber. HIPS filaments are commonly used to support ABS and ASA parts and don’t need a heated build chamber.

You should also consider how you will remove the structural support filament from your finished part. Soluble filaments are well suited to print parts with complex or fragile designs as they gently dissolve off your primary part, leaving a smooth finish. Water-soluble filaments dissolve in a heated bath. Limonene-solvent-soluble filaments do not require heating, but the solvent will need to be properly disposed of after use.

Impact-Resistant ABS 3D Printer Filaments

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.

SMA ABS filaments have a styrene additive that makes them easier to print and reduces warping during cooling. These filaments also form strong bonds between layers, so prints will not split apart.

Carbon-fiber-filled ABS filaments make rigid parts that are difficult to bend and break. Their parts can also be threaded and machined more easily than ABS filaments without a filler. Carbon-fiber- and fiberglass-filled filaments are abrasive, so you should use them with an abrasion-resistant nozzle. They will wear out other nozzles.

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.

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.

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.

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.

Carbon-fiber-filled polycarbonate filaments make rigid parts that are difficult to bend and break. Parts made from these filaments can also be threaded and machined more easily than parts made from polycarbonate filaments without a filler. Fiberglass-filled polycarbonate filaments make parts that are less likely to warp or shrink than parts made from polycarbonate filaments without a filler. Both carbon-fiber- and fiberglass-filled filaments are abrasive, so you should use them with an abrasion-resistant nozzle.

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

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.

UV- and Impact-Resistant ASA 3D Printer Filaments

Best for outdoor use, parts made from these ASA filaments are UV resistant, so they won't warp or crack from prolonged sun exposure. They’re also durable, so they absorb impact without breaking and won’t degrade when heated.

Use with 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.

3D Printer Filaments for Casting

Mold Shown with 3D-Printed Part

Create molds around parts printed with these filaments. They’re PVB, so they vaporize cleanly from your mold, similar to wax in traditional investment casting and lost wax casting. For a smoother surface on your mold, before casting you can apply isopropyl alcohol to remove the layer lines from your printed parts. Apply using a brush, sprayer, or vapor bath.

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.

Foam-Forming 3D Printer Filaments

Print these polypropylene filaments into filters, gaskets, and other lightweight, foam-like parts that let air and gas pass through but repel water. They contain a filler that dissolves in water, forming hollow spaces that make up 45% of the part. Polypropylene is known for being rigid yet flexible, so it absorbs impacts and bounces back to shape after bending, making these filaments good for compressible seals and living hinges. It also resists hydrocholoric and phosphoric acids, as well as other nonoxidizing acids and bases.

These filaments work with fused filament fabrication (FFF) 3D printers. If using a glass print surface, apply an adhesive to prevent the filament from detaching. The recommended print speed is 25 mm/s. While polypropylene is likely to shrink, the filler in these filaments supports your design, preventing it from losing shape as it prints. Submerge your part in hot water for about 24 hours after printing to dissolve the filler and expose the pores.

For extra support when printing complex designs, use structural support 3D printer filaments. They dissolve in water at the same time as this filament’s filler.

Moisture-Resistant Polyester 3D Printer Filaments

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.

PETT forms strong bonds between layers, so prints will not split apart. It is often used to make large models with large layers.

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

PCTG is more impact resistant than PETT and 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 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 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.

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.
