Material Conditions

Printing Conditions, Drying and Hardware

Material	Applications	Drying and feeding	Printer and nozzle
TPU	Feet, protective covers, flexible connectors	Typical drying start: 45–55°C for 4–6 hours. Direct-drive feeding is preferred for softer grades.	Use a controlled filament path, low print speed and conservative retraction.
ASA	Outdoor housings, drone accessories, UV-exposed parts	Keep sealed and dry when surface quality or long prints are required.	Enclosed printer recommended; heated bed, controlled cooling and brim help reduce warping.
PA6-CF	Jigs, fixtures, robot structures, mechanical components	Typical drying start: 80–90°C for 8–12 hours. Print from a dry box when possible.	Hardened steel nozzle required; 0.4–0.6 mm nozzle and enclosure recommended.

Application Matrix

Application	Primary option	What to validate
Outdoor parts	ASA	UV exposure, enclosure temperature, bed adhesion and dimensional tolerance.
Drone components	ASA / PA6-CF	Choose ASA for outdoor housings; PA6-CF for stiff structural components after load testing.
Robot parts	PA6-CF / TPU	Use PA6-CF for rigid structures and TPU for protective or flexible interfaces.
Jigs and fixtures	PA6-CF	Drying, print orientation, nozzle wear and final dimensional inspection.
Print farms	TPU / ASA by job	Dedicated profiles, dry storage, enclosure capacity and repeatable material handling.
