Materials
Pick filament and resin from the job, not the marketing.
The cheaper resin package can cost more per kilogram
Compare the upfront price and cost per kilogram of two exact grey resin packages using a dated manufacturer receipt.
MaterialsPLA, PETG or ABS: start with the part
Choose a first material by environment, load, surface and printer constraints instead of a universal strength ranking.
MaterialsHeat-adjacent housings: a temperature note is not a rating
Shortlist materials for a housing near a warm component using family heat notes, then keep the test method attached to every number.
MaterialsOutdoor printed parts: start from family guidance, not a weather sticker
Use documented outdoor-use family notes to shortlist materials for a clip or cover that will sit outside, then verify the exact SKU.
MaterialsAdvanced filament should buy a specific property
Evaluate flexible, outdoor, nylon, polycarbonate and fiber-filled formulations against the part and the machine that must print them.
MaterialsCount the plastic that becomes a useful part
Separate material claims from local disposal reality, and measure waste and energy per accepted part.
