i3DMFG™ Electronic Discharge Machining


Wire Electronic Discharge Machining (Wire EDM)

Electrical Discharge Machining (EDM), also called spark machining, spark eroding, or wire erosion, is a precision manufacturing process through which, a desired shape is cut to held tolerances of up to +/- .001 mm using electrical discharges across a fine wire. i3DMFG™ utilizes the precise CUT 30P’s strict tolerances to remove parts from its DMLS® build plates.

Many of our customers have found that there are less complex, but high tolerance parts that are well-suited to production on the Wire EDM. With minimal set-up time for intricate cutting patterns, the CUT 30P is a perfect complimentary manufacturing process.

Material is removed from the base stock through a series of rapidly recurring current discharges between two electrodes (the ‘tool’ electrode and the ‘work-piece’ electrode), separated by a dielectric liquid and subject to electric voltage.

Key Statistics:

  • Wire diameters from 0.15mm to 0.30mm
  • Accuracy of up to .001mm
  • Conductive materials to any hardness (i.e. steel or titanium)
  • Surface finish as fine as 5 microns

Metals We Print

i3DMFG is one of the few 3D manufacturers in the US that specializes in aluminum, copper, titanium, Inconel, Haynes, Monel K, Stainless Steel and custom metal powder applications. Experts in 3D design, our engineers help our customers achieve competitive advantage in design and proprietary advancements.

Metals We Print

Aluminum (AlSi10 and 6061)

Due to its lightweight nature and excellent thermal properties, AlSi10 is our most common DMLS aluminum powder. It is ideal for parts with thin walls and complicated geometries. i3DMFG™ also runs 6061 to achieve better surface finish and strength properties comparable to wrought 6061-T6.

Titanium (Ti)

Titanium (Ti64) is well suited for projects requiring corrosion resistance, strength, weight reduction, and biocompatibility.

Stainless Steels (15-5, 17-4, 304L, and 316L)

DMLS® stainless steel is a medical grade, sterilisable, corrosion resistant steel that hardens to 40-45 HRC after heat treatment. Our stainless-steel equivalents include 15-5, 17-4, 304L, and 316L. Parts made from DMLS® can be machined, spark-eroded, welded, micro shot-peened, polished, and coated.

Maraging Steel (MS1)

Maraging (tool) Steel (MS1) features excellent strength and mechanical properties. Its chemical composition corresponds to U.S. 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. After heat treatment, MS1 typically has a 50-53 HRC.

Super Nickle Alloys (IN625, IN718, Haynes 214, Haynes 282 and Hastelloy X)

Super Nickle alloys are chromium alloys with superior heat and corrosion resistance.

Copper (GrCop-84 and GrCop-42)

i3DMFG™ is developing parameter sets to print in GrCop-84 and GrCop-42 for high temperature applications.

A NASA developed Copper alloy that is highly conductive for the aerospace industry.
