Looking for materials stronger than Nylon for FDM based printers.

Sumant · 2014-10-24T11:41:05.000Z

We are looking for strong FDM materials so that the end prints can be made stronger. Apart from nylon, we have tried a few carbon fiber based materials (these usually contain 5% carbon fiber particles mixed in plastic). However, we have not found these to be any stronger than Nylon.

Would be great if people share ttheir experiences on printing with carbon fiber or other materials.

Let me ask the material guys @ColorFabb @Proto_pasta @Faberdashery. Also maybe experts like @Christian_CAD may help out here

Hi.

Have you tried T-GLASE PETT?

I would look at these guys - http://taulman3d.com

Proto-pasta PC-ABS is also very tough and worth considering in your investigations. You need a heated bed (ideally volume) and an all metal hotend. Its now available in black for a more standard production material aesthetic. I wish we had a bit more comprehensive material data but something is better than nothing, especially in the 3D Printing space: Our Story – ProtoPlant, makers of Proto-pasta As engineers, we are very interested in performance materials, but so far the hardware on the market is our limitation. There are a lot of great materials that no one could process with low cost, open architecture machinery…

@Design_for_Craft sure you can help Sumant with your best suggestion!

Hi there. I’m Emilio, DfC and stickfilament.
There are lot of materials stronger than Nylon. The best thing to do i s charge it with mineral powder.
We recommend to not use carbon fiber or fiberglass with brass hotend because the fibers enlarge the hole in 3-4 prints.
If you decide to use carbon fiver and fiberglass steel hotend is recommended.

We developed the stable PLA HS that is a bite stronger than ABS and Nylon.
We are developing a special nylon charged with fiber glass that is incredible stronger but difficult to use anyway… so i is soon to speak about experimental polymers.

We are test a special PP with mineral fibers that is sufficiently stronger to produce engine parts… I’ll update about it in this chat.

Bests

Proto-pasta PC-ABS is a good special material. But i’m not sure it works on every 3d printer on the market.
I’ve to test it in all of my machines.

Interesting topic!

I’m keeping an eye on this post so I can add new materials to my just-released Comprehensive List of 3D Printing Filaments.

Markforged has the printer for this but it’s far from cheap. Nylon is the primary material and a continuous carbon fiber, fiberglass, or kevlar layer is printed in as a composite structure. It’s the strongest parts your going to get with FFF at the moment.

Hi, I am a newb in this domain and would like to start in the world of 3d printing. will buy soon an zyyx printer or the flashforge pro. I have some few projects and will need a very strong filament. I have the same question as you. I am thinking about to buy nylon and PETG. I saw that polycarbonate also exist; did you try it? Polycarbonate (PC) - 1.75mm (0.75kg) | MatterHackers

Nice thread. I came here hoping to see figures of 3D filament materials strength relative to one another. For example, Nylon print material is known to be stronger than ABS and PLA. If PLA tensile strength to be 57.8MPA, what figure do we have Nylon? . Can someone point me in the right direction? Figures like this are what design is based on. Thanks.
