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

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.

Thanks for your reply. To be clear, I don't have a problem with the premium price. It's just an entry barrier to evaluation.
It might help to understand that there are many, many products that have come out lately with pretty impressive claims. It's simply impossible to justify buying a full roll of all of them.
I would like to clarify though, is there a shelf life to the GF30-PA6?
Thanks
John
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.

Naah its not that difficult if you use the smartmaterials3d smart stick ? Totally loved that ?
well good to know thank you!

Another question that came in via a different channel: Do you also experiment with other additives to give different properties to filaments, like conductive filaments?
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.

Wow, that is pretty amazing! Was it eventually used as an end use part, in the race or just as a prototype? Do you know if they also sanded the model before coating it? I know XSTRAND has a bit of a rougher texture, which can be great depending on your use but since it is so strong, I wonder what they used to sand the surface (if they did).
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.

I know there's a lot of properties and factors involved, but in your mind, what is the main factors that would make you choose GFPA6 over GFPP or vice versa?
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.

Have you made any 3D prints with XSTRAND yourself where the properties of XSTRAND were an important factor?
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.

I did a annealing on the PA6GF30, and the result was really nice, the parts become a bit stiffer and stronger ?
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.

For the PA6 Xstrand you can use the PVA or breakaway supports and even HIPS.
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

Have you tried the various support materials offered by Ultimaker on your materials? Does PVA or Breakaway supports work?
For the PA6 Xstrand you can use the PVA or breakaway supports and even HIPS.

One question I have about this, and other new, exotic (my term) filaments centers on the high cost of trying it out. The only way I can access most filaments here in Canada is to buy the smallest retail roll, which is too much for a trial and has a high risk of being wasted if I don't store it properly or it sits too long before I have a project big enough to consume the whole roll.
This creates a bit of a vicious cycle - I won't quote on a job using filament I'm not sure will work for me, and I can't justify the cost of buying filament to try out unless I have work for the amount I plan to buy.
How about a half-retail size (or something like that) trial roll or coil so we can get used to the filament?
Thanks for arranging this AMA!
John
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?

@AD_XSTRAND_OC , can you tell a little bit more about this model? Sure doesn't look like the XSTRAND prints I've seen ?
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.

How does the addition of glass fibers increase strength (physically)?
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

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 settings. If you are using a printer other than Ultimaker the general rule is to print the PA6 Xstrand close to the default nylon settings as a good start (230-260°C) and for PP Xstrand use the default settings close to ABS. A heated chamber does help out with extremely large parts.

Hi! Thanks for doing the AMA!
There's a lot of composit materials coming out on the market now with CF being the most popular for strength, what specific advantages does Glass fiber have over CF?
Thanks!
Glass fiber reinforced parts are non conductive, radiolucent, have better impact resistance than CF, glass load can goes up to 50% where CF is oftenly limited to 15%. So it is possible to have a better stiffness with GF than CF. This is true for Thermoplastic short fiber reinforcement, not true with continuous fiber.

What is the Izod impact strength of Xstrand and what is its specific gravity/density?
Density for GF30-PA6 is 1.17g/cm², GF30-PP is 0.94g/m²
I only have the Charpy unnotched impact for GF30-PA6 for now which is 56KJ/m²

I'll start then! ?
- How many printers did you broke during your tests?
- Using the Mohs scale of hardness, what was the hardest material you were able to successfully print and what level of hardness was it?
- Which of your currently available material gave you the most troubles during the conception and testing phase?
- Do you think that 3D printing can one day become as easy and simple than the famous replicators seen on Star Trek?
1- haha we don't break printers we use Ultimakers
2-Mohs scale is used for mineral material. For thermoplastics materials Shore D or Rockwell R scale is more relevant. PA6 or PP reinforced with 30% glass are in the range of 100 to 120 Rockwell R
3-GF30-PP was the most challenging product to develop. It gave us a hard time to find the right material both for filament manufacturing, printability while keeping excellent mechanical properties.
4-Yes but not in the next 20 years…good question hahah

They have two kinds nylon(PA6GF30) and PP(PPGF30) i have the settings for bed and nozzle will put them up and yes a warm chamber helps, and both have to be dried pre-printing, so maybe getting a print dry or your own DIY dry feeding helps, will put the part pictures here soon for everyone to see ?
Only the PA6GF30 needs dried
