With nylon as an additive, PCTPE filaments are flexible, slippery, and wear resistant. They’re good for making sturdy components that move and rub against other objects. Since they're UL rated 94 HB and 94 V-2, they prevent the spread of flames both horizontally and vertically.

Print these filaments on a fused filament fabrication (FFF) 3D printer. Because they’re flexible, they require a slow feed rate so they don’t jam. Store them in a sealed container with a desiccant, or use a dehumidifying cabinet, since moisture in the air can degrade their printing quality.

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.

Fabricate custom bottles, packaging, and other parts for chemical processing. Made of PPS, 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, PPS 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.

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 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.

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.
