  1. Hips works great as a support for PA6
  2. Gabriele, We are sorry for the initial experience with X-Strand. Our team is working hard to get the corrected Print profile updated in CURA. For the time being can you mimic these settings? Retract 12 MM at a sped of 40 mm/s first layer height of .12mm for 0.1mm layers Adhesion solution: Blue tape, Dimafix, Elmers Glue Stick printing speed 25-40 mm/s Print temp-240°C Regular Fan Speed - 50% Build Plate Temp - 60°C Infill Speed- 50 mm/s Initial Layer speed 20 mm/s Minimum Speed 5 mm/s Minimum Layer Time - 3 s Build Plate Adhesion -skirt
  3. Hi... this is Adam at Owens Corning. We have not directly compared the ONYX material vs Xstrand. When it comes to additive manufacturing vs Milled parts it depends on the end use and end goal when it comes to choosing a material and a printer. I can't speak on behalf of the Markforged system but I can include our TDS as a reference. If you send me a private message I'd like to chat further about the parts you are trying to print. Design and orientation can be critical when making the jump from subtractive to additive manufacturing.

  4. John, I believe Emmanuel answered your other question but as for the shelf life...you are looking at 10 years as long as the storage complies with the TDS document which states it must be stored in a dry and temperate location and should remain in original packaging.
  5. So far we never tried others additives than glass. Core competencies of Owens Corning is fiberglass reinforcement, so we want to stick to it for now.
  6. I'm not sure if it has been used or will be used. In fact this was the first one made and it was just finished with coating about 2 weeks ago so still early in the process. Yes they sanded and primer prepped the part first. Very similar process as what you would do if you were using bondo.
  7. If I'm deciding GFPP or GFPA6 it comes down to size and surface finish. If I'm looking for something with amazing surface finish I would choose the GFPP. If the part is large or the surface area that is touching the build plate consumes most of the area I would choose GFPA6 as there is no warping issues. GFPP can be tricky to print large flat parts.
  8. My main role within Owens Corning is to produce line trial prototypes, fixtures, replacement parts, etc within our own manufacturing plants. Because of our line of work the ambient temperature in areas of the plant are elevated where PLA or ABS wouldn't work. Strength is also very important when it comes to testing line trial prototypes.
  9. we have not officially completed annealing testing however I would agree that in personal experience annealing will make a noticeable difference which is true for most 3d printed parts.
  10. For the PP Xstrand I prefer to use PPxstrand as the supports for best results. Set gap between the top support layer and the bottow layer part to 0.10-0.15mm
  11. For the PA6 Xstrand you can use the PVA or breakaway supports and even HIPS.
  12. John, we do have 50 Gram samples. I believe Emmanuel can go into more detail into about acquiring them. Would 50 grams be enough or are you thinking more?
  13. good question. This is a custom mirror housing for a corvette that was designed by Pratt & Miller to use on their racing vehicles. We then had a company called Tru Designs apply a special coating to it.
  14. 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
