PLA, PETG, ABS, TPU: All you need to know about the materials used for your 3D printed parts

When you purchase a 3D printed part from L'Atelier 3D, you receive an object designed to last. Behind every product is a meticulous selection process for the most suitable material for its intended use. Car parts, storage accessories, decorative items: each category has its constraints, and each filament has its qualities. This article explains which materials we use, why, and what that specifically means for you.

The importance of material choice in a 3D printed part

A 3D part is not just a shape: it is first and foremost a material. The filament determines the strength, heat resistance, durability, flexibility, and even the visual appearance of the final object.

A poor material-use combination can lead to the part deforming, breaking, or deteriorating prematurely. This is why, at L'Atelier 3D, we systematically select the appropriate filament for each product's function. You don't have to worry about it: we've already done it for you. This article simply allows you to understand what you're holding in your hands.

PLA: the material for our decorative pieces

PLA (polylactic acid) is a plastic of plant origin, made from corn starch or sugarcane. It is an eco-friendly, aesthetic, and precise material, particularly well-suited for decorative objects.

Why we use it for decoration

• Exceptional visual rendering, with a wide variety of finishes (matte, glossy, silk, glitter, wood or metal effects)
• High precision for reproducing fine details
• Vibrant and stable colors over time indoors
• Renewable-source material, more environmentally friendly

You will find it in

• Vases, candle holders, plant pots
• Statuettes, figurines, sculptures
• Frames, decorative letters, signs
• Personalized gift items
• Display pieces and stands

Good to know: PLA is designed for indoor use. It cannot withstand prolonged exposure to high heat (above 60 °C) or direct sunlight. A PLA decorative piece placed in your living room, on a shelf or furniture, will last for years without changing.

PETG: the material for our storage parts

PETG is an engineering plastic derived from PET (the material of water bottles), modified to offer better resistance and durability. It is the filament we favor for all parts intended for daily use and regular handling.

Why we use it for storage

• Excellent resistance to impacts and bending
• Does not deform below 80 °C
• Impervious to moisture
• Resistant to many household products
• Strong without being brittle

You will find it in

• Storage boxes and bins
• Drawer organizers, modular dividers
• Wall mounts, hooks, coat racks
• Screw organizers, tool organizers, workshop accessories
• Pencil holders and office accessories
• Kitchen and bathroom holders

PETG is also perfectly suited for use in humid environments or sheltered outdoor areas (covered balcony, garage). An L'Atelier 3D storage part made of PETG is designed to last for a long time, even with intensive use.

ABS: the material for our car parts

ABS is a leading engineering plastic in the automotive industry. It makes up a large part of your car's interior components (dashboard, trim, buttons), as well as LEGO bricks and many appliance casings. Its robustness and temperature resistance make it the ideal material for car parts.

Why we use it for car parts

• Heat resistance up to approximately 100 °C, essential in a car interior that can get very hot in summer
• Excellent resistance to impacts and vibrations
• Long-term dimensional stability
• Mechanical strength compatible with intensive use

You will find it in

• GPS mounts and phone holders for cars
• Covers, clips, and interior fasteners
• Replacement buttons and knobs
• Center console and dashboard parts
• Trunk and cabin accessories
• Vehicle repair and personalization parts

TPU: the material for our flexible parts

TPU (thermoplastic polyurethane) is a flexible and elastic filament. It bends, stretches, and returns to its original shape, making it essential for a whole family of parts where flexibility is crucial.

Why we use it for flexible parts

• Durable flexibility and elasticity
• Excellent abrasion resistance
• Very good fatigue resistance (can be bent thousands of times without breaking)
• Comfortable to handle and natural non-slip effect

You will find it in

• Protective covers and bumpers
• Seals, tips, stoppers
• Straps, bands, flexible fasteners
• Furniture pads and protectors
• Non-slip accessories
• Certain flexible car parts (seals, covers, protectors)

A TPU part offers performance that no rigid plastic could achieve: it is the material of comfort and durability in deformation.

Summary table of the materials we use

Our commitment to quality at L'Atelier 3D

Choosing the right filament is only part of our expertise. For each part we manufacture, we also master:

• The printing parameters (temperature, speed, infill rate) to ensure optimal strength
• The orientation of the parts to maximize their resistance in the stress zone
• The finishes for a clean and durable result
• The quality controls before shipment

It's this invisible work that makes the difference between an ordinary 3D part and an L'Atelier 3D part designed to last.

Frequently asked questions about 3D printing materials

Is a 3D printed part as strong as an industrial part?

For the vast majority of domestic and automotive uses, yes. PETG and ABS achieve mechanical performances very close to factory-injected parts, with the added possibility of being repaired or remanufactured individually.

Do your car parts withstand the heat of a car interior in summer?

Yes. This is precisely why we use ABS for this category. It easily withstands the high temperatures that a car interior can reach in summer.

Are your storage parts dishwasher safe?

PETG tolerates occasional low-temperature dishwashing, but we recommend hand washing to preserve their lifespan.

Can your decorative pieces be used outdoors?

The PLA we use for decoration is designed for indoor use. For an object intended for a sheltered outdoor area (covered balcony, veranda, covered terrace), we adapt the material by using PETG, which is more resistant to humidity and temperature variations.

Are your parts eco-friendly?

PLA is plant-based and is the most environmentally friendly filament. For other materials, we minimize waste and prioritize quality filaments where possible.

Can a 3D printed part be painted?

Yes, all our materials accept acrylic paint or special plastic spray paint. ABS is particularly well-suited for painted finishes for customization enthusiasts.
