Material selection articles

Connect a part’s load and service conditions to specific filament grades, test evidence and the next verification step.

Mechanical performance

Choosing an FDM material for a load-bearing part

Screen specific PLA, PETG, ASA and PC Blend grades by the failure mode, then check orientation, sustained loading and the limits of published coupon tests.

PC-CF vs PA6-CF vs PA12-CF for structural components

Compare named carbon-filled FFF grades through service moisture, tensile direction, impact behavior and the processing needed to reproduce the published coupons.

Creep and stress relaxation in FDM parts

Use measured creep and retained-stress evidence to screen continuously loaded brackets, locating fixtures and fastened joints, with time, environment and control mode kept attached.

Service environment

Heat resistance under load: HDT, Tg, annealing and service temperature

Read thermal measurements by their method, stress and material state before selecting a hot fixture, housing or tool. An HT-PLA example shows why annealing and load belong beside the temperature.

Nylon in service: PA6, PA12 and PPA after moisture conditioning

Select exact nylon grades for their service moisture state, with separate unreinforced copolymer, carbon-fiber and PPA evidence; distinguish mass uptake, dimensional change and retained mechanical properties.

ASA vs PETG vs PC for outdoor components

Separate UV, moisture, sun heating and appearance requirements using named FDM grades, documented exposure protocols and specific verification tests.

Selecting FDM polymers for chemical exposure

Choose candidates by the named liquid, concentration, temperature, exposure time and load; separate immersion observations from stress cracking, permeation and retained properties.
