LASER SINTERING (LS)

An additive manufacturing process using a CO2 laser to sinter (fuse) durable thermoplastic powder into functional 3D objects. Some benefits of LS are:

  • - Durable, functional parts
  • - Low-volume, end-use production parts
  • - Living hinge and snap capabilities
  • - Variety of nylon and elastomeric materials
  • - Fixtures, jigs, and assemblies
  • - Rapid tooling
ADDITIVE METALS (DMLS)

An additive manufacturing process using a high-wattage fibre laser to fuse fine metal and alloy powder into functional 3D objects. Some benefits of DMLS are:

  • - Rapid turnaround
  • - Low-volume, end-use production parts
  • - Build complex parts easily
  • - Suitable for heat treating or HIP processing
  • - Can be machined, polished, or painted
FUSED DEPOSITION MODELING (FDM)

A process that extrudes thermoplastic filament along tool paths to build functional 3D objects layer-by-layer. Benefits:

  • - Production-grade thermoplastics
  • - Good dimensional accuracy for large parts
  • - Excellent repeatability
  • - Moderately good feature detail
STEREOLITHOGRAPHY (SL)

A layer-additive build process that uses a (UV) laser to solidify liquid, photo-sensitive resins. Some benefits of SL are:

  • - Clear and opaque materials
  • - Layers as small as .002 inch (two thousandths)
  • - Fine feature detail
  • - Light-duty, functional prototypes
  • - Presentation models
  • - Casting patterns

3D PRINTING

Similar to inkjet printers, most machines in this process deposit material or binder from print heads to create three dimensional (3D) objects. Options include:

  • - Polyjet
  • - Z-Corp
  • - Projet

 

CASTING / MOLDING

Cast reproductions of SL and LS patterns from temporary molds. Options include:

  • - Urethane casting (RTV tooling)
  • - Plaster casting
  • - Investment casting
  • - Sand casting
  • - Spin casting
  • - Rapid and traditional injection molding

MACHINING

A subtractive process by which a high-speed cutting machine removes unwanted material from a billet of raw material. Some benefits of CNC are:

  • - Wide selection of plastics, metal, and alloys
  • - Tight tolerances
  • - Sharp feature detail
  • - Functional prototypes
  • - Excellent repeatability
POST PROCESS / FINISHING

Harvest has developed a variety of proprietary post-processing and finishing techniques to provide our customers with an outstanding final product, including:

  • - Sanding
  • - Priming, painting, and clear-coating
  • - Polishing and texturing
  • - Machining
  • - Plating
  • - Inserts, helicoils, and tapping
  • - Assembly
