SLS TPC Elastomer is our flexible material for powder bed fusion. It delivers dense parts with high stretch, quick rebound, and strong tear strength. Detail is clean and small features print well. The natural surface shows a grain and this is normal for this material. We offer dye only for this material.
It performs well around oils, sunlight, and outdoor use. Use it when parts must flex and still hold their shape, such as seals, bellows, soft grips, cable boots, snap lids, and vibration mounts.
Selective Laser Sintering uses a laser to fuse thin layers of TPC powder inside a heated chamber. TPC is a thermoplastic copolyester elastomer that behaves like tough rubber. Loose powder supports the part during the build so no extra supports are needed. This enables internal channels, thin walls, and complex shapes with steady size. Parts stretch and spring back after load with reliable energy return. Design with smooth transitions and radii to avoid stress points.
Seals and gaskets that need stretch and a tight seat.
Bellows and dust covers that flex through many cycles.
Cable boots and strain reliefs that protect against bend and pull.
Vibration mounts and bumpers that absorb shock and reduce noise.
Soft grips and handles for repeated squeeze and better feel.
Snap lids and flexible hinges where parts must bend and return.
Flexible couplers and ducts that allow movement and keep leaks low.
Protective sleeves and edge guards for tools and fixtures.
Elastic performance. High stretch with fast rebound and strong tear strength for parts that bend and return to shape.
Dimensional behavior. Good size hold in normal use, with more creep than nylon under constant squeeze.
Light weight and tough surface. Flexible parts are light and resist scuffs, with a natural grain that feels rougher than nylon.
Chemical resistance. Stands up well to oils, fuels, greases, and many solvents, which suits seals and fluid facing parts.
Thermal capability. Works in warm environments but is not for continuous high heat service.
Production ready workflow. SLS supports nesting and part stacking to lower unit cost without changing the design.
Finish options. Dye option is only available.
Has good temperature resistance a little less then the Nylon options.
The material has low tensile strength but better then most elastomers.
The material has good flexural strength for an elastomer but lower then the nylons.
With great elongtion at break well over 300%, the material is suitable for many bending applications.
Impact resistance is the best of our SLS materials due to the elastomeric properties.
The TPC does have a polymer backbone as part of the chemistry making the distortion resistance better then other elastomers.
One of the most chemically inert plastics. Can handle water, greases, oils, fuels, hydraulic fluids, and many solvents
Can be used in outdoor environments including UV sunlight. Select dye option to hide slight color change over time.
We optimize our powder fed fusion systems with regular calibration and thermal profile control to achieve best possible accuracy and tolerances.
This is the thinnest wall we can successfully build. You may accept thinner walls at your own risk.
This is the smallest thickness for raised text or fine features. Measure the stroke width of the detail, not the full width of a letter.
This is the smallest depth for recessed text or fine grooves. Measure the stroke width of the cut, not the full width of a letter.
This is the smallest hole we can clear of powder. Longer or twisting holes need larger diameters so the powder can exit.
This is the gap needed between two mating pieces such as a lid and a box. Double the value for each facing surface such as interlocking components.
Large flat shapes can warp as they cool. Try to add ribs or design reliefs before printing wide plates. We may angle parts in the build if necessary.
This is the smallest angle we recommend to avoid visible layer lines. We optimize part orientation for resolution, accuracy and build speed.
Sharp corners should use a radius. Rounded edges stay stronger and resist damage during handling and finishing. Chamfers are also better.
