CNC - Computer Numerical Control

 

 

FDM - (Fused Deposition Modeling)

A Coil of ABS Plastic is heated and it is extruded
Each layer is built on top of the previous layer
Typical resolutioin is 100 layers per inch

• Strength: Excellent (A)
• Detail: Above Average (B)
• Build Time: Long
• Cost: Medium

Architectural Applications:
Interactive Models / Presentation Models / Exterior Buildings /
Floor Plans / Small Massings / City Review Board / HOA Boards

Polyjet - Objet

Machine jets photopolymer material in ultra-thin layers
Each layer is cured by an UV light right after it is applied
Model is fully cured after build and then must be cleaned

• Strength: Average (C)
• Detail: Excellent (A)
• Build Time: Medium
• Cost: High

Architectural Applications:
Specific Details (i.e. wrought iron work) / Colplex Geometry /
Interior Detail

SLA - Stereolithography

A vat of liquid resin (photopolymer) is utilized
A laser traces a cross section on the surface
A UV laser cures&solidifies the pattern traced

• Strength: Average (C)
• Detail: Above Average (B)
• Build Time: Medium
• Cost: Medium

Architectural Applications:
Massing Models / Exterior Buildings / Interior Floor Plans

SLS - Selective Laser Sintering

A laser traces a cross-section of powder
Each layer is solidified and the bed of powder is lowered
The process is repeated until the part is complete

• Strength: Excellent (A-)
• Detail: Above Average (B+)
• Build Time: Medium
• Cost: Medium

Architectural Applications:
Presentation Models / Exterior Buildings / Limited Floor Plans / Small Massings / City Review Board / HOA Boards

Z-Corp - Powder Printer

Uses inkjet technology
A liquid is jetted onto the surface of a bed of powder
The layer solidifies and a new layer of powder is added
The process repeats until the part is done

• Strength: Average (C)
• Detail: Above Average (B)
• Build Time: Fast
• Cost: Low

Architectural Applications:
Massing Models / Color Models / Interior Detail / Floor Plans

TOP

 

Milling - CNC

Subtractive process
Starts with a high-density polyurethane foam
Machine cuts away unnecessary material
Color image is then printed directly on the surface

• Strength: Above Average (B)
• Detail: Above Average (B)
• Build Time: Medium
• Cost: Medium

Architectural Applications:
Topography / Massing Models / Topography with Site Plan
