  1. Glass fibers have a much higher tensile strength than regular glass (200-500 times stronger than regular glass) Typical value of tensile strength for fiberglass is in the range of 1900 to 2000 MPa
  2. GF30-PP is perfect for such application. Watch out this video that we did with our partner SEAIR, a startup that is developping foil for marine application.
  3. John, send a note to 3Dprinting@owenscorning.com and our team will be happy to provide you some samples of material :)
  4. A continuous fiber will provide higher strength and stiffness than a short fiber, allowing for printing semi structural to structural parts.
  5. A new material development requires about 6 to 9 months. We are not using computer simulation for now. XSTRAND filament is a combination of polymer, fiberglass and additives mixed all together to ensure the right material viscosity for a perfect printability, a good processability ( filament manufacturing ) while maximizing the mechanical and thermal performances. All of this requires a lot of iterations and experiments.
  6. The most important factor is to have a perfect adhesion of the glass with the matrix. This is the role of the chemistry that is added to the glass surface. This will provide a strength increase. If adhesion is poor, it will act as a defect in the material and the risk to have crack propagation will increase.
  7. XSTRAND materials have the strength and characteristics to set the bar at a much higher level than before, while keeping an excellent printing capability and part quality, justifying a premium price. GF30-PP is not sensitive to moisture, so it can be reused directly from the shelf. Only GF30-PA6 or Nylon must be re-dried before printing if the material as been exposed outside from its original sealed bag. It is a reversible process that doesn’t affect the material performance. There is no risk to damage or waste the product.
  8. We have a close relationship with ROSSIGNOL, a famous French ski-slope outerwear and equipment manufacturer that help us to develop and optimize our materials during the development phase last year. They did test GF30-PP in cold room up to -20°C and it passed all the test. Check the case study clicking the following link :
  9. Correct, you can lay the GF30-PA6 spool on your heated bed for a few hours before use
  10. Only for PA6 Xstrand you will need to place the material into an oven at 80-90°C for a few hours. A good way to test if the moisture ha been removed from the material is to bend the filament with your hands. If the material bends rather than breaks then allow more time in the oven. Dried material will snap when you try to bend. XSTRAND GF30-PP have a high resistance to cracking, acids, organic solvents. GF30-PA6 is chemically resistant to oils and fuels, gasoline, mineral spirits, and some alcohols. Recommended print temperatures for the Ultimaker can be found in the Cura
