Selection Notes

State rigid or flexible formulation, stock grade, contact media, electrical requirements and geometry.

CNC uses machinable sheet or rod stock. Verify its grade and formulation separately from similarly named molding and printing materials.

CROSS-PROCESS SELECTION

One material name. Different manufacturing routes.

Separate actual polymer families from performance-like resins, then compare feedstock, grade and application for each process.

Identical Material Across FourThis catalog does not establish one identical material and grade across all four processes.

Polymer Family Across ThreePA/Nylon: CNC, molding and printing; confirm species such as PA6, PA66 and PA12 separately.

Polymer Families Across TwoCNC and molding: ABS, PC, PMMA, POM and PEEK. PVC also requires rigid/flexible formulation checks.

Actual Polymer

Same Family; Confirm Species and Formulation

PA/Nylon spans CNC, molding and printing, but PA6/PA66 and PA12 are different species. ABS, PC, PMMA, POM and PEEK span CNC and molding at family level. Confirm PVC formulations. This catalog does not establish an identical material and grade across all four processes.

ENGINEERING & QUALITY

Turn a material name into clear part requirements

Grades, reinforcement and processing affect finished-part behavior. Share the operating conditions so selection and acceptance follow the same requirements.

Explore Quality Control→
01

Start with the application

Loads, operating temperature, chemical exposure and dimensions define the material properties to check.

02

Define appearance and processing needs

Specify color, clarity, finish, assembly and quantity so material and process can be reviewed together.

03

Confirm samples and inspection

Share a specified grade or performance target, then agree samples, critical dimensions and material documentation.

MATERIAL QUESTIONS

Frequently Asked Questions

Have a Material Question?↗
Which materials are shared across these four processes?

Within this catalog, the PA/Nylon family appears in CNC, molding and printing, but the species differ: CNC nylon stock with a specified species, PA6/PA66, and PA12 or nylon composites. ABS, PC, PMMA, POM and PEEK appear in CNC and molding. PVC also has two routes; confirm each formulation rather than assuming equivalence. Casting like-resins are separate performance alternatives; no identical material and grade is established across all four processes.

Are ABS-like and PC-like casting resins the named plastics?

No. These names describe appearance or selected performance targets. These casting options are resin systems and do not identify actual ABS, PC, PMMA, POM or PA. Obtain the actual resin grade and review strength, heat exposure, aging and service conditions. A successful fit-check prototype does not automatically establish equivalent long-term performance.

Can PA6, PA66 and printed PA12 be exchanged directly?

They are not direct substitutes. They share the polyamide family, but polymer species, formulations, reinforcement and manufacturing routes differ. Specify grade, loads, temperature, humidity and fits, and agree on dry or conditioned inspection states. Identify fillers explicitly; glass fiber and glass beads must not be merged under an unspecified reinforced-nylon label.

Can clear 3D print resin be treated as PC or PMMA?

Transparency does not establish polymer identity. The clear and translucent Resin options are photopolymers, while PC and PMMA are thermoplastics with their own grades. For a viewing window or cover, compare appearance, thickness, finishing, loads and environment across the routes, using each material’s own data.

How do flexible PVC, CNC PVC and TPE/TPU differ?

Flexible molding PVC and CNC PVC can be compared at family level. Specify rigid or flexible formulation and stock grade for CNC rather than assuming identical formulations. TPE is a thermoplastic-elastomer family that includes TPU. For flexible parts, define chemistry, hardness, rebound, contact conditions and any overmolding substrate. Cured casting PU is also distinct from thermoplastic TPU.

What information should accompany a material-selection request?

Provide CAD or drawings, quantity, critical dimensions and fits, plus loads, peak and continuous temperatures, chemical contact, color, clarity and finish. If a material is specified, include its full grade, filler, hardness and required records; add conditioning requirements where relevant. Separate visual, functional-validation and long-term service objectives so material, process and finishing can be reviewed together.
