Proto Pasta has some new filaments with enhanced properties then regular PLA / ABS.

Proto Pasta offers:
Carbon Fiber Reinforced PLA
Proto-Pasta Carbon Fiber reinforced PLA is made from NatureWorks 4043D PLA Resin compounded with 15% by weight Tenax short chopped Carbon Fibers. It is designed to be stiff, or to resist bending. It is the stiffest material we offer and makes parts with an incredibly solid feel. When printed, this material is a dark glossy black that glitters slightly in direct light from the fine chopped fibers reflecting the light.
Carbon Fiber Reinforced PLA does not require a heated bed and prints much like unreinforced PLA filament. The main difference is that it is brittle and care must be taken when handling the filament and loading the printer.
We have had good results printing at 190C-210C using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head. Layer adhesion is excellent and the material has low warpage.
High Temperature PLA
Proto-Pasta High Temperature PLA is made from a custom compound consisting of mineral filled impact modified PLA with a nucleating agent to help promote crystallization. Crystallization after printing is what gives this material added heat resistance. To fully realize this advantage, parts must be soaked in hot water or an oven after printing at 60C-80C for 3-5 minutes. This crystallizes the material and makes it much more heat resistant. It does not require a heated bed to print well, but this may help crystallize the material after printing and make oven soaking unnecessary for some parts. High Temperature PLA is a glossy off white, or very light gray. Printed parts look good and have slightly more texture than standard PLA. This material is not translucent like standard PLA.

Layer adhesion is good and the material has low warpage.
Polycarbonate/ABS Alloy
They also offer Reusable filament Folding Spool

Proto-Pasta Polycarbonate-ABS (PC-ABS) Alloy is an incredibly tough material designed for strong, resilient parts. When printed, PC-ABS is bright glossy white.
Proto-Pasta PC-ABS Alloy can print well. It is very moisture sensitive and even if stored bagged with desiccant, drying in an oven for ~ 1hr at 85C-95C may be required for bubble free high strength prints. Layer adhesion can be an issue if the part is large or the temperature is too low. We have had good success printing parts ~60mm long at 260C-280C using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head. A heated bed may help warpage and layer adhesion on larger/thicker parts.
