PLA
A generally easy, stiff filament family commonly chosen for visual parts, prototypes and low-heat indoor uses.
Uses and printing guideFilament decisions
3D Printing Materials
Compare typical FDM filament families. Formulations, pigments and filled variants can differ, so use these sourced ranges as a starting point and check your spool maker’s profile.
Choose material for a partCompare two materials
Choose by the job and the equipment
For outdoor parts, compare sunlight, actual operating temperature and sustained load separately. For brackets and holders, consider layer direction, stiffness, impact and creep rather than selecting a family from a single rating. Exact formulations and filled variants need their own evidence.
Use the selector for application requirements, then check the exact printer and nozzle system. The partial-spool calculator owns next-job sufficiency; solid volume and density do not replace complete slicer consumption.
Storage versus active drying is a separate equipment decision. No local stock or retailer availability is inferred from a product-family name.
Compare material families
Start with the part's function, then check the exact spool and printer workflow. Product-sheet values describe the named formulation and test, rather than every part in the family.
| Family and reason to investigate | Preparation that changes the workflow | Decision needing product evidence |
|---|---|---|
| PLA visual prototypes, display models, dimensionally tidy indoor parts | Choose a build surface supported by your printer and PLA profile. Prusa notes that its smooth PEI sheet is useful for small contact areas; that is specific equipment guidance, not a setting for every printer. | Is the prototype only for fit, or will it remain in service? Read the named product example |
| PETG everyday functional parts, light moisture exposure, moderate impact | Check the release instructions for the exact build plate. Prusa cautions that PETG can bond too strongly to smooth PEI; use the surface and separation method specified for your equipment. | Will supports be accessible after printing? Read the named product example |
| ABS heat-tolerant housings, post-processed functional parts | Follow the exact build-sheet and material instructions. Do not transfer a release or adhesion method from another surface without checking its compatibility. | Can the printer maintain the required environment? Read the named product example |
| ASA outdoor enclosures, weather-exposed brackets | Check the selected sheet and the exact ASA profile together. Preparation that works on one plate coating is not automatically suitable for another. | Does the outdoor requirement concern the polymer or the whole enclosure? Read the named product example |
| TPU flexible parts, vibration damping, protective bumpers | Flexible materials can adhere strongly to a plate. Use the build-sheet supplier and filament maker instructions for release, rather than increasing adhesion by default. | Does the part need to bend, compress or simply grip? Read the named product example |
| PA / Nylon wear parts, tough functional components | Select the surface and drying/storage procedure for that formulation. A profile for a filled PA product is not evidence that a different unfilled nylon will behave the same way. | Will moisture exposure change between the trial and the long job? Read the named product example |
| Polycarbonate / PC high-heat functional parts, tough engineering components | Confirm the exact blend and sheet combination, including any required release layer. Do not generalise a PC Blend surface instruction to every polycarbonate formulation. | Does a small successful print represent the full footprint? Read the named product example |
| Polypropylene / PP chemical-contact components, living hinges, lightweight parts | Prusa recommends its PP sheet or other PP-specific preparation for the appropriate product. A PEI setup used for PLA should not be assumed suitable for PP. | Is the challenge first-layer adhesion or the intended bend? Read the named product example |
How to read the evidence
- Family guidance: a qualitative starting point, such as PETG support-removal or surface-adhesion preparation.
- Published product data: a named formulation, document revision, property and test context. TPU hardness needs its Shore scale; a PA11 result does not describe PA6.
- Your observation: a measured fit, mass or deformation from your own recorded process. It does not become a manufacturer property.
For example, an HDT result under a stated load does not specify continuous operating temperature. Read source conditions before comparing numbers. InspectMesh has not physically tested these filaments.
