IMECA3D — FDM materials
3D printing materials we work with
Every material has strengths and limitations. We print eight material families and more than 25 grades — from everyday PLA to carbon-fibre nylon — on Bambu Lab P1S and P1P printers. This page helps you understand the differences and choose correctly for your project.
Three questions decide the material
1. Define the function
Is the part decorative, structural, or under load? A display model and a functional bracket have completely different requirements — and the wrong material will fail.
2. Consider the environment
Heat, moisture, UV, and chemicals each degrade specific materials. Outdoor parts, electronics enclosures, and indoor displays all have different exposure profiles.
3. Match the mechanical demand
Impact, fatigue, and wear resistance vary significantly across materials. Use the comparison below or contact us — we'll confirm the right choice before printing.
Eight material families
The most precise FDM material we print in. PLA delivers clean surface finishes, sharp details, and excellent dimensional accuracy. Use it for visual prototypes, concept models, and presentation parts where appearance and precision matter most.
Read the full PLA guide →Our most-used functional material. PETG balances strength, moisture resistance, and printability in a way no other standard material does. It handles real-world conditions — enclosures, outdoor fixtures, functional brackets — without the printing complexity of ABS.
Read the full PETG guide →When parts need to survive drops, impacts, and elevated temperatures that PLA or PETG cannot handle, ABS is the answer. A long-established engineering plastic used in automotive interiors, power tool housings, and industrial enclosures.
Read the full ABS guide →Tough, wear-resistant and good under repeated loading. Unfilled PA12 for gears, hinges and wear parts; carbon- and glass-fibre grades for stiff, strong and heat-resistant structural parts.
Read the full Nylon guide →ABS-like strength and heat resistance, but built to withstand sunlight and weather. The choice for parts that live outdoors. Also available as carbon-fibre ASA-CF.
Read the ASA guide →The strongest and most heat- and impact-resistant of the unfilled materials we print. For functional parts that take real loads, knocks or heat.
Read the polycarbonate guide →Rubber-like, flexible and extremely impact- and abrasion-resistant. Printed in 95A, 90A and 85A shore hardness, from firm to soft.
Read the TPU guide →A very stiff, heat-resistant composite that holds its dimensions well. Brittle under impact, so it suits parts with steady loads.
Read the PET-CF guide →Material and printer compatibility
All grades are printed on our Bambu Lab P1S (enclosed) and P1P (open frame) printers. Materials that need a warm, enclosed chamber are printed on the P1S only; carbon- and glass-fibre grades are printed with a hardened steel nozzle.

* Nylon is hygroscopic — it absorbs moisture during storage, and proper drying is required before printing. Values are typical for FDM-printed parts and vary with print orientation, settings and filament brand. ASA, PC, TPU and PET-CF are covered in their own guides above.
