Choosing the Right Material for Products That Sell: PLA, PETG, TPU
Pick by function, not hype. The ten materials on the shelf today, and which one each kind of product wants.
A phone case in rigid PLA cracks the first time it is dropped. A planter in the wrong plastic slumps in a sunny window. Neither seller picked a bad filament — they picked by name instead of by what the product has to survive. Answer that one question and the material picks itself.

What does the product have to survive?
Print it in
PETG Translucent
PETG gives a little before it breaks, where PLA snaps. It shrugs off water and a drop onto a kitchen floor.
Also right: PETG Basic.
Reading the rack…
Every swatch is a spool on our rack right now, at its real price. Need one that is not here? We buy it in against your first order, no surcharge.
Price a part in itThe mistake we see most
It looks perfect in the listing photo and cracks in the customer’s hand.
The fixAnything that bends when it is used — cases, straps, bumpers, feet — is TPU. No exceptions.
The finish is half the sale
The lever most sellers never pull: Matte, Silk and Glow cost the same per gram as PLA Basic or within a cent of it — the rack above shows the live price — and a buyer reads them as a different price bracket.
- Matte
- Kills the shiny “3D-printed” look and hides layer lines. The right call for figurines, minis and anything with fine detail.
- Silk
- A pearlescent, near-metallic sheen. Jewellery, gifts and display pieces look like they cost more than they did.
- Glow
- Charges under light and glows in the dark — a genuine feature on toys, night lights and novelty pieces, not just a colour.
- Wood
- Real wood fibre in the filament: matte, warm, and it takes sandpaper and stain like the real thing.
You are choosing how the product photographs as much as how it performs — pair the finish with the shot in product photos that sell 3D prints. For the measured numbers behind these picks — heat and impact for every plastic on the rack — see materials for parts people handle every day.
What FDM is — and is not — the answer for
Everything on the rack prints on Bambu Lab machines, up to 255 mm on any axis. Resin, powder-bed nylon and anything cast, sintered or machined are different processes, not different spools. Carbon fibre is not on that list: PETG-CF prints here every day.
Resin wins one job outright — sub-millimetre miniatures. For the products that actually sell in volume (organisers, stands, planters, personalised gifts, pet gear, brackets) the right FDM material is tougher, cheaper and far kinder to a parcel. And if the spool you need is not on the rack, we buy it in against your first order at no surcharge; it stays on the rack after.
Material is half of durability
Design is the other half. Wall thickness, a stable base and real tolerances decide whether a product arrives in one piece — see designing 3D prints that sell.
FAQ
There isn’t one — it depends on the product. PLA for display items, PETG for functional or handled parts, ABS for heat, TPU for anything flexible. Match the material to what the product has to survive.
No — we’re FDM-only. Resin is better for ultra-fine miniatures but is brittle and harder to ship. For the products that sell well, FDM in the right material is the stronger choice.
Yes. PETG-CF — PETG filled with chopped carbon fibre — is on the rack today, and PET-CF is in the catalogue. It is stiffer and holds its dimensions better than plain PETG, with a deep matte finish, which makes it the one to pick for brackets, mounts and jigs rather than decor.
Basic is the crisp workhorse, Matte hides layer lines for a premium look on detailed pieces, and Silk has a pearlescent metallic sheen for jewellery and gifts. The rack above shows the live price per gram of each.
PLA is cheaper, crisper, and great for display pieces. PETG is tougher and weather-tolerant, better for anything that gets handled, dropped, or lives outdoors. Choose by use, not by default.
