3DXTech has launched two new grades of carbon fiber PLA and ABS - called
3DXMax™ CFR. The data will be uploaded this weekend - but a preview is that the 3DXMax™ CFR carbon fiber PLA has about 50% greater stiffness (flex modulus) than ProtoPasta CF PLA - and is less expensive - includes free shipping - what more can I say!
Very cool stuff if you need something for a structural part.
