For an Industrial Designer, the best approach is to use specialty suppliers rather than one general craft store:
For Orange County specifically, Paragon, Industrial Plastic Supply, and MatterHackers give you an unusually useful local combination for an ID studio.

Industrial designers can find the best professional-grade modeling foams, plastics, resins, and hardware components through specialized industrial suppliers like McMaster-Carr for raw stock and hardware, Smooth-On for casting resins and silicones, and Alro Plastics for engineering plastics.
| Material Category | Best Used For | Typical Source |
|---|---|---|
| High-Density Foam (Urethane/XPS) | Ergonomic volume studies, large form models | McMaster-Carr or local insulation suppliers |
| Industrial Styling Clay | Organic surfaces, automotive, hand-sculpted contours | Chavant or specialized sculpt supply sites |
| Engineering Plastics (ABS/Acrylic) | Functional structural parts, clear enclosures | Alro Plastics or local plastic distributors |
| Casting Resins & Silicones | Duplicating parts, flexible overmolds, short runs | Smooth-On distributor network |

For an Industrial Designer, the best material sourcing strategy is usually a mix of specialty model-making suppliers, industrial suppliers, local hardware stores, and maker/fab labs. The “best” source depends heavily on whether you're making a rough appearance model, a functional prototype, or a polished presentation model.
| Material | Great for | Where to look |
|---|---|---|
| Foam / urethane tooling board | Form studies, CNC prototypes, sculpting | McMaster-Carr, specialty model suppliers |
| Foamcore / XPS | Fast concept models, mockups | Art stores, craft stores, architecture suppliers |
| Basswood / balsa | Detailed models, structures | Model-making suppliers, art stores |
| MDF / plywood | Bases, structures, CNC/laser cutting | Lumber suppliers, hardware stores |
| Acrylic / PETG / polycarbonate | Transparent parts, housings, lenses | Plastic suppliers, McMaster-Carr |
| Styrene sheet | Product shells, panel details, vacuum-forming masters | Model-making/plastics suppliers |
| Aluminum / brass / steel | Functional prototypes, mechanisms, premium details | McMaster-Carr, Online Metals, local metal suppliers |
| Silicone / urethane | Casting, flexible prototypes, molds | Smooth-On and industrial suppliers |
| Modeling clay / plastiline | Ergonomic studies, sculpting | Art/model-making suppliers |
| 3D-printing resin/filament | Complex geometry, functional parts | Filament/resin suppliers and print services |
| Hardware & fasteners | Mechanisms, joints, assemblies | McMaster-Carr, local hardware stores |
A useful rule is don't buy everything from an art store. Industrial-design prototyping often benefits enormously from suppliers carrying real engineering materials. For example, McMaster-Carr has dedicated prototyping foam that can be hand-carved or CNC-machined, along with plastics, metals, hardware, and other prototyping stock.
For immediate local sourcing, I'd start with:
For a serious Industrial Design materials library, I'd actually recommend building a small “material pantry” containing foam, basswood, MDF, acrylic, styrene, cardboard, aluminum, fasteners, magnets, tubing, adhesives and assorted found objects. Physical prototyping works particularly well when you can rapidly combine conventional stock with manufactured components and found materials.
If you tell me whether you're a student, professional designer, or hobbyist, I can also give you a curated “Industrial Designer's materials shopping list” with specific materials, thicknesses, tools, adhesives, and the best suppliers for each.
- **Arizona Art Supply** - 4025 N 16th St, Phoenix, AZ 85016, United States - **Andy's Hobby Headquarters** - 2150 S 91st Ave, Tolleson, AZ 85353, United States - **Hobby Depot** - 109 E Southern Ave, Tempe, AZ 85282, United States
For an Industrial Designer, the best material source depends heavily on whether you're making a quick form study, appearance model, functional prototype, or production-intent prototype. A good workflow is to use different suppliers for different material families, rather than trying to find everything at one store.
Best for foam board, museum board, chipboard, basswood, balsa, clay, adhesives, tools, and finishing materials.
For the basic physical-model palette, foam board → chipboard → basswood/balsa → acrylic covers a surprisingly large percentage of concept and presentation models.
These are much more valuable once you're doing real prototypes rather than architectural-style study models.
This is where I'd go for acrylic, ABS, PETG, polycarbonate, HDPE, Delrin/acetal, PVC, etc., rather than buying craft-store plastic.
For industrial-design form studies, rigid urethane modeling foam is excellent. It can be carved, sanded, machined and painted, and higher-density grades work well with CNC routers.
A particularly useful local source is Reynolds Advanced Materials, Phoenix in Tempe. It's geared toward mold making, casting, urethane materials, silicone, sculpture and professional fabrication, so it's a step beyond ordinary hobby stores.
For hardwood, plywood, veneers and larger pieces of wood, don't limit yourself to model shops.
For scale models, basswood is generally preferable to balsa when you need crisp, durable detail; balsa is lighter and faster to cut.
For an Industrial Designer, I'd also maintain relationships with a laser cutter, CNC shop and 3D-printing service.
Laser-cuttable materials such as acrylic, basswood, plywood, cardstock, cork and foam can dramatically speed up iterative prototyping.
The key is to ask a fab shop which materials they already stock rather than buying material first. Some materials—including PVC, certain foams and plastics—can be unsafe to laser.
If I were setting up a professional ID studio, I'd keep:
| Material | Best use |
|---|---|
| 5 mm foam board | Fast form/massing studies |
| 1–2 mm chipboard | Thin shells, templates, packaging |
| Basswood sheets/strips | Precise appearance models |
| Balsa | Very quick lightweight forms |
| 1/8" acrylic | Lenses, windows, transparent components |
| Styrene sheet | Plastic product surfaces and details |
| ABS sheet | More functional plastic prototypes |
| Rigid urethane foam | Sculpted/CNC'd forms |
| Plywood | Structural prototypes, jigs, fixtures |
| Epoxy putty | Filling, sculpting, modifying forms |
| Silicone + urethane resin | Mold/cast iterations |
| 3D-printing filament/resin | Complex geometry and functional prototypes |
| Aluminum/brass stock | Functional/detail components |
The biggest upgrade is learning to think of materials as design tools, not merely construction supplies. Foam is great when you're asking “Does this shape work?”; acrylic/wood/styrene when you're asking “Does this object look right?”; and machined/printed plastics when you're asking “Does this mechanism actually work?”
If you're in the Phoenix area, I'd particularly combine Arizona Art Supply + Reynolds Advanced Materials + an industrial plastics supplier such as Professional Plastics or Plastifab + Woodworkers Source. That gives you a very broad physical-prototyping ecosystem without relying exclusively on online ordering.

| Design task | Materials I'd reach for |
|---|---|
| Fast ideation | Cardboard, chipboard, foam core, Bristol |
| Ergonomic studies | XPS foam, urethane modeling board, clay |
| Form development | High-density polyurethane foam |
| Appearance models | ABS, styrene, acrylic, MDF, urethane board |
| Functional prototypes | Nylon, PETG, ABS, acetal/Delrin, aluminum |
| Clear parts | Acrylic, polycarbonate, PETG |
| Flexible parts | Silicone, urethane rubber, EVA |
| Fine details | Styrene strip/rod/tube, brass, aluminum |
| Casting | Silicone + polyurethane resin |
| Finishing | Epoxy putty, body filler, primer, wet/dry paper, paint |
A particularly effective workflow is:
Cardboard → foam → urethane modeling board → 3D print → CNC plastic → cast/metal prototype
That progression lets you answer increasingly expensive design questions only when necessary. For example, foam is fantastic for asking “Does this shape feel right?”, while CNC-machined plastic or aluminum answers “Does this actually function?”
If you're located around Yonkers/Westchester, I can also put together a local Industrial Designer's materials-shopping map—say, the 10–15 best places within ~30–60 minutes for plastics, foam, wood, metal, model supplies, 3D printing, laser cutting, and fabrication.
