TPS is a styrenic thermoplastic elastomer. Makers sell it for seals, shoe materials and uses needing rubber-like elasticity, and its glass transition is -59 °C. On the H2C it prints at 225–245 °C, but a maker says it prints only with a direct-drive extruder and at low speed, and another advises drying before printing.

Partly documented Tensile modulus (XY), tensile strength (XY), tensile strength (Z) and price rest on 1 product each and notched Charpy impact is not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials

Among the materials, TPS has a high elongation at break (XY) and a low tensile modulus (XY), tensile strength (XY), tensile strength (Z) and price: each is in the top or bottom quarter of the materials that publish it. Its density sits in the middle half.

Against its alternatives, TPS has the lowest tensile strength and tensile strength (Z)

What makers say about printing it

Printing advice

  • Use brim for better bed adhesion. Fillamentum Flexfill TPE 90A, data sheet, p. 1
  • It is recommended to use a short-range double-wheel deceleration extruder designed for flexibility, and eLastic materials cannot be printed by a remote extruder. eSUN TPE 83A, data sheet, p. 2
  • After a long printing time, impurities may remain in the nozzle, so it is recommended to use it with cleaning filament. eSUN TPE 83A, data sheet, p. 2
  • If necessary, pleasw replace the nozzle and throat with new ones. eSUN TPE 83A, data sheet, p. 2
  • Workability of 3D printing filament is at least 12 months from delivery. Fillamentum Flexfill TPE 96A, data sheet, p. 1
  • Try your own settings before printing. Fillamentum Flexfill TPE 96A, data sheet, p. 1
  • As with other flexible materials, the smaller the filling and the thinner the wall thickness, the more elas+c the printed component remains. Fabru Thermoplastic styrene block copolymer elastomer (TPS), data sheet, p. 1

Moisture sensitivity

  • it is recommended to dry the filaments (55℃/> 4h) before printing to achieve the best printing effect, and it would be better to use together with eBOX when printing. eSUN TPE 83A, data sheet, p. 2
