Materials & Techniques

Architectural model materials: a practical guide.

Choosing the right material for an architectural scale model affects detail, durability, weight, cost, and the final impression. Below is how we match materials to project goals at our Montréal workshop.

R

Resin

Fine detail, smooth surfaces

Best for: Intricate facades, windows, small ornamental parts, museum replicas.

Made with: SLA 3D printing

Pros

  • Layer heights as low as 25 µm
  • Captures fine texture and edges
  • Excellent paint adhesion

Considerations

  • Brittle if dropped
  • Needs UV post-cure
  • Higher cost per part

Finish

Wet-sanded, primed, airbrushed, then sealed with matte or gloss clearcoat.

A

Acrylic

Crisp edges, luminous effects

Best for: Glazing, curtain walls, water features, modern towers, display cases.

Made with: Laser cutting + CNC

Pros

  • Clean, transparent edges
  • Can be etched or frosted
  • Very stable over time

Considerations

  • Can show fingerprints
  • Scratches if mishandled
  • Less forgiving for complex curves

Finish

Flame-polished or laser-etched, then bonded with solvent-free acrylic cement.

W

Wood

Warmth, tradition, structure

Best for: Heritage models, timber framing, display bases, luxury presentation pieces.

Made with: Laser cutting + hand joinery

Pros

  • Premium look and feel
  • Strong for structural elements
  • Accepts stain and oil finishes

Considerations

  • Moisture-sensitive
  • Can warp if not sealed
  • Heavier than foam or acrylic

Finish

Sanded, stained or limed, then sealed with museum-quality wax or lacquer.

Hybrid Workflow

Why we combine 3D printing with hand-finishing.

Digital fabrication gives us accuracy and repeatability. Hand-finishing gives us materiality, nuance, and a model that reads as architecture rather than a print. The combination is what lets a model perform in a sales gallery, at a public hearing, or in a museum for years.

Digital fabrication

We print or cut the structural geometry first. SLA resin captures micro-detail, laser cutting gives acrylic crispness, and CNC foam shapes large terrain.

Tolerance checking

Every printed part is checked against the architectural drawings before assembly. This is where 0.1 mm matters, and where digital precision earns its keep.

Hand finishing

Machines get the shape; artisans get the soul. We sand, prime, paint, weather, and add translucent details by hand to match the model's intent.

Final assembly

Components are bonded, aligned, and lit. Removable elements are tested so the model works as a presentation tool, not just a sculpture.

How to Choose

Match the material to the moment.

For sales & marketing

Choose resin and acrylic for detail, wood for warmth, and integrated lighting to make the model feel finished and aspirational.

For planning & approvals

Use acrylic massing blocks for fast studies, then upgrade to resin and wood detailing for the final presentation model.

For museums & exhibitions

Prioritize stable, sealed materials: acrylic, sealed wood, and museum-grade resin. Lighting and protective casework extend the model's life.

For shipping overseas

Lightweight foam cores and modular acrylic shells reduce weight without sacrificing display impact. We crate every international shipment.
