Technology

TOMOSM is a manufacturing technology that uses precision, three-dimensional, lithographically derived tooling. The following diagram illustrates the TOMO manufacturing process applied to the fabrication of a multi-layer, continuous flow chemical reactor.

Step 1

Solid Model

Solid model design using Solid Works, ProEngineer, etc. Model can be used for finite element analysis during design phase.
Step 2

Sliced Model

Solid model is digitally sliced into thin (≥ .002 inches) layers
Step 3

Photo Tools

Digital layers are converted into photo tools.
Step 4

Etch Layers

Pattern on photo mask is transferred to (typically) copper substrate via a photoresist and a chemical etching process. The result are etched layers representing the entire 3D object.
Step 5

Stack Layers

Etched layers are stacked and bonded (laminated) to create the master tool.
Step 6

Derive Mold

Complex, 3D molds derived from master tool.
Step 7

Casting

Parts are cast with application specific material or materials.
Step 8

Final Processing

Sinter, reaction bond, bake, etc., depending on the material.
Step 9

Assembly

Final assembly of layers, components, or modules if required.
