Material selection

Choose around the complete project—not only the machine that will cut it.

Material choice affects appearance, structural behavior, edge quality, weight, fastening, bonding, finishing, packaging and service life.

A practical material review begins with the intended use, fabrication method and environment, then considers thickness, finish, availability and quantity.

Compare rigid, flexible, transparent, lightweight and acoustic options.

Review routing, laser cutting, knife cutting, forming, printing and assembly together.

Account for pickup, shipping, installation and repeated handling.

Material selection guide

Start with the project conditions.

These questions help narrow realistic material choices before quoting or prototyping begins.

Where will it be used?

Indoor, outdoor, wet, dry, heated, public-facing or frequently handled.

What must it do?

Carry load, protect, diffuse light, absorb impact, reduce sound or provide visual finish.

How will it be fabricated?

Routing, laser cutting, knife cutting, bending, forming, drilling, printing or assembly.

What should it look like?

Clear, mirrored, matte, colored, painted, printed, textured, illuminated or exposed.

How many are required?

One prototype, a custom installation, a short run or a repeat multi-location rollout.

How will it ship or install?

Flat-packed, assembled, nested, palletized, locally collected or shipped nationwide.

Fabrication compatibility

A general starting point for matching existing materials to available processes.

Exact compatibility depends on the material grade, thickness, coating, finish and required edge quality.

Material CNC routing Laser cutting Knife cutting Typical applications
ACM Good fit Not typical Limited Signs, cladding, panels and display structures
Polycarbonate Good fit Process review Limited Guards, covers, enclosures and protective panels
Re-board or Hexacomb Material dependent Material dependent Good fit Displays, furniture, packaging and partitions
Acrylic Good fit Good fit Limited Signage, lighting, displays and clear components
Rubber foam Material review Material review Good fit Padding, gasketing, cushioning and backing
Plywood Good fit Thickness review Limited Furniture, fixtures, panels and routed parts
PET acoustic material Process review Grade review Good fit Acoustic shapes, wall panels and ceiling features
Material safety, fumes, heat response, coating, reinforcement, thickness and machine limitations must be reviewed before production. A listed compatibility does not mean every grade or thickness is automatically suitable.

Material FAQs

Common questions before choosing a fabrication material.

Final recommendations depend on the exact grade, thickness, finish, fabrication process and intended application.

Ask the Shop
Can 865FabLab help select a material?
Yes. Material choices can be reviewed around fabrication process, appearance, strength, weight, environment, quantity, finishing and delivery requirements.
Can I supply my own material?
Customer-supplied materials may be considered subject to condition, compatibility, dimensions, available test material and process review.
Which existing material is best for lightweight displays?
Re-board, Hexacomb, ACM, acrylic, plywood and PET acoustic material may each suit different display requirements. The best choice depends on size, finish, handling, structure, reuse and shipping.
What is the difference between acrylic and polycarbonate?
Acrylic is frequently selected for visual clarity, signage, displays and laser-cut features. Polycarbonate is often selected where increased impact resistance is important. Exact grade and application requirements should be reviewed.
Can ACM be routed and folded?
Compatible ACM products can be routed, profiled, V-grooved and folded for signage, panels, enclosures and architectural features. Core type, thickness and finish should be confirmed first.
What is PET acoustic material used for?
PET acoustic material can be fabricated into decorative wall panels, ceiling features, branded shapes and customized interior acoustic elements.
What files help with a material recommendation?
CAD files, vector artwork, dimensioned drawings, sketches, reference images and information about use, quantity, finish, installation and deadline are useful.
Do material colors and finishes vary?
Yes. Color, gloss, texture, transparency and surface appearance may vary by manufacturer, grade and batch. Samples may be appropriate for appearance-sensitive projects.
