ADDITIVE MANUFACTURING MATERIAL OPTIONS
POLYJET MATERIALS
The range of material options offered for PolyJet-based machines, combined with the excellent resolution and surface finish, makes PolyJet FATHOM’s most popular technology choice. For rapid prototyping, form modeling, aesthetic pieces, and anything requiring a high level of detail or accuracy, PolyJet is an ideal fit. Photopolymer resins are specially formulated to simulate common plastics or flexible parts. An array of digital materials are available, created through the blending of Vero rigid resin with Tango flexible resin, allowing for specifically tailored material properties along the spectrum from rigid to rubber-like.
Vero: Fully rigid and available in glossy or matte finishes
  • Color: Black, white, or clear
  • Easy to sand, prime, and paint
  • Clear option is nearly translucent when sanded and clear-coated
TangoBlackPlus: Rubber-like plastic
  • Color: Black
  • Shore 27A durometer — mid-level elasticity
  • Flexible glue can be used to join parts
TangoPlus: Flexible translucency
  • Color: Clear
  • Very similar material properties to TangoBlackPlus
  • Special custom setup material
DM Shore: Rubber-like digital materials with varying Shore A values
  • Color: Black
  • Fully opaque
  • Choose from 40A, 50A, 60A, 70A, 85A, and 95A Shore A values
  • Softest 40A is comparable to TangoBlack, while 95A is the hardest, with the lowest elongation at break (35-45%)
  • Tensile strength ranges from 1.3-10.0MPa
DM Grey: Rigid and durable digital materials for snap fits and parts needing slight flexibility
  • Color: Light to medium bluish-grey colors
  • Choose from 20A, 25A, 35A, 40A, 50A, and 60A Shore A values
  • Flexural strength ranges from 75MPa (Gray 20) to 35MPa (Gray 60)
ABS-Like: Closely simulate injection-molded ABS
  • Color: White
  • Most functional PolyJet material option with the highest heat deflection
  • Features under 1.0mm do not reach optimal material properties
  • Closely simulates the material properties of the ABS thermoplastic
Endur: Polypropylene-like plastic
  • Color: Off-white
  • Simulates appearance and functionality of polypropylenes
  • Suitable for snap-fits, durable housings, and prototype packaging
FDM MATERIALS
FATHOM’s production centers quickly and efficiently produce functional, detailed, accurate parts in production-grade thermoplastics. FDM is the technology of choice for functional testing, end-use parts, structural parts, jigs, production fixtures, large models, moving parts, assemblies, and more.

Orientation can be specified to optimize either strength or surface finish — numerous post-processing options are available. Sparse fill patterns can save time and reduce weight, while voids and other complex geometries are made possible using support material.
ABS: High durability
  • Color: White
  • Medium strength
  • Popular, common option
  • Tough, hard, and rigid
ASA: High durability
  • Color: White
  • Medium strength
  • Improved UV stabilization over ABS
  • Ideal for large builds and general purpose functional models
PC/ABS: High strength and heat resistance
  • Color: Black
  • Strength and durability
  • Very good heat resistance
PC: Superior mechanical properties
  • Color: White
  • High tensile and flexural strength
  • Excellent heat resistance
Nylon: Flexibility and toughness
  • Color: Black
  • High impact and fatigue resistance
  • Low friction
  • Excellent for snap-fits and parts requiring some flexibility
Ultem 9085: Highest performance, FST-rated
  • Color: Black or tan
  • Extremely high strength to weight ratio
  • Suitable for aerospace and automotive applications
  • Heat deflection temperature of 307°F (153°C)
Ultem 1010: Ultimate resistance to heat and chemicals
  • Color: Tan
  • Higher tensile strength, lower impact resistance than Ultem 9085
  • Autoclave sterilizable, bio-compatible and food-safe
  • Heat deflection temperature of 399°F (204°C)
ABS-ESD7: Static-dissipative thermoplastic
  • Color: Black
  • Static-dissipative variant of ABS
  • Ideal for electronics assembly fixtures
SLS MATERIAL
Nylon PA2200 is strong, tough, and dense, resulting in stiff but durable parts. It is excellent for parts as large as 280mm x 280mm, can handle extremely complex geometries, has very high accuracy and fine tolerances, and rarely shows layers.

SLS parts are bright white and can be dyed, and have an even surface finish approximately the texture of fine sandpaper. Excess powder used as support material must be physically removed in post-production, thus voids or hollows must be accessible.
