Start with what the object must do, where it will be used and how it is loaded. Compare PLA, PETG, flexible TPU and nylon, then include a colour preference. The exact grade and available colour are confirmed in the quote; a material name alone does not establish suitability.
A material name alone does not predict how your part performs. Use these questions to make the enquiry specific.
01Use
Decoration, a shape model, holder, clip or another functional part?
02Environment
Indoors or outdoors, temperature, moisture, sunlight and contact with substances.
03Behaviour
Stiffness describes resistance to bending. Toughness concerns deformation before breaking. Flexibility describes how readily something bends or compresses. Which movement should your part allow?
04Verification
Which dimension, fit or load should a trial check? Wall thickness and layer direction affect behaviour too; the material name does not determine the result by itself.

What do material properties mean for your part?
These descriptions support a choice; they are not guaranteed product specifications. Design, orientation, layer structure and the exact grade all matter.
01
Usual starting point
PLA
For shape, detail and many indoor parts where high heat or sustained heavy loads are not central requirements.
Character
Relatively stiff and useful for defined shapes and fine details.
Often considered for
Decoration, shape models, architectural models, fit trials and simple indoor parts.
Discuss first
Heat, impact, sustained loading, outdoor use and critical connections.
A broad material family considered for toughness, movement or wear. Variant, moisture condition and production process can substantially change the result.
Character
Often tougher and more deformable; not automatically stiffer or stronger for your design.
May suit
Clips, clamps, sliding or moving concepts tested in realistic conditions.
Remaining stiff, springing back and fitting another part are different requirements. Describe movement, load and the mating object before selecting PLA, PETG or TPU.
Give black, white, grey or another colour as a preference. A name, screen colour or RAL reference does not establish an exact match. Layered prints described as transparent are usually translucent rather than glass-clear.
This is a preference, not confirmation of stock or suitability. Exact grade, colour, price and schedule follow in the quote.
Questions about choosing filament
Is PETG better than PLA?
It depends on use. PLA is often a starting point for shape, detail and indoor applications. PETG may suit moisture, impact or a different stiffness/toughness balance. Geometry, grade, orientation and load remain part of the assessment.
Which filament is strongest?
There is no universally strongest filament. Tensile strength, stiffness, toughness, layer adhesion, heat, moisture and load direction can point to different choices. Explain what the part supports and what happens if it fails.
Can I specify an exact colour or RAL reference?
You can supply a preference or reference. A screen colour, name or RAL code does not prove that an exact match is available or technically suitable. The achievable colour and any ordering time are confirmed in the quote.
Will transparent PETG be glass-clear?
Not automatically. Layer lines, geometry, wall structure, settings and finishing affect the appearance. Discuss the optical result you expect before choosing transparent or translucent material.
Can you print TPU or nylon?
You can request either for assessment. Neither is a general stock or fulfilment promise. We assess the model, required behaviour, exact grade, production route and risk before quoting.
Do I have to choose a material first?
No. Select ‘Not sure yet’ and describe function, environment, load, critical dimensions and appearance. We assess whether PLA or PETG is sufficient or another route is needed.
