TOMO Specifications

TOMO Specifications

TOMO can fabricate two and three-dimensional parts having micron size features in traditional materials such as metals, polymers, ceramics, cermets, and composites.

Feature Specification

Near Net Shape

 Parts are cast with such precision that finishing steps such as machining and grinding are significantly reduced or not required.

Repeatability of Tooling
  1. Feature location accuracy: <5 microns (<.0002 inches)
  2. Repeatability of feature size: ±12.5 microns (± .0005 inches)

Large Footprint

 Square meter for a single tool. Greater than a square meter for modular tooling. High aspect ratio (height to width) – greater than 25:1 Monolithic structures can be up to one centimeter thick; composite structures can be up to fifty centimeters thick.

High Precision Features

 Repeatability of feature size: ±12.5 microns (± .0005 inches). Material- and geometry-specific.

Application Specific Materials

 Polymers, ceramics, metals, cermets and other composites.

Complex Geometries
  1. Three-dimensional capability: undercuts, blind features, and protrusions can be designed into monolithic structures. Not limited by draft angles. Reduces part count and associated process stages. Also reduces the opportunity for defects and promotes product quality.
  2. High surface area: hybrid lithographic/non-lithographic shape capability.
  3. Non-uniform, engineered arrays

Multi-Layer Capability

 Unique materials in different layers of an assembly can address structural, thermal management, and conductive (magnetic and dielectric) needs.

Alignment Features
  1. Engineering tiling – dovetails and lap joints
  2. Alignments related to functionality
  3. Integrate components into assemblies

Speed

 8-12 weeks for tooling

Digital Tooling

 Digital process to create master tool.

  1. Process begins with a digital, solid-modeling tool (e.g. Solid Works, ProEngineer, etc.).
  2. Rapidly convert into sliced/layered lithographic tools.
  3. Master tool created through etching and bonding process.

Remake tooling over and over again using a very repeatable lithographic process. Tools can be made anywhere – don’t require clean room environment Tooling art has been removed.
