What is Digital ABS HT?
Digital ABS HT is Digital ABS heat treated to HT — use when the part must survive short exposure near 90 °C (e.g. injection-mould inserts, hot-air fixtures); toughness drops slightly. Digital ABS HT has a tensile strength of 60 MPa (8.7 ksi), stronger than 68% of polymer grades. Elongation at break is 15% and the elastic modulus is 3 GPa (0.435 Msi). Digital ABS HT has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 50°C (122 °F).
Limitations
- Absorbs moisture — dry before molding — 1.7%, worse than 94% of polymer grades
- Degrades in UV without stabilisers — 20/100, worse than 88% of polymer grades
- Difficult to weld — 10/100, worse than 82% of polymer grades

Working with Digital ABS HT
Is Digital ABS easy to machine?
Light drilling, reaming and tapping are practical with sharp tools and slow feeds; the crosslinked acrylic is notch-sensitive so avoid heavy cuts and keep parts cool.
Can Digital ABS be welded?
Not weldable (thermoset); bond with cyanoacrylate or two-part epoxy, avoid acetone-based solvent cements which craze the surface.
Can Digital ABS be formed, bent or molded?
Shape is fixed by PolyJet jetting/UV cure — design for 0.6 mm minimum wall (1.2 mm for load-bearing), remove SUP70x support fully, and post-cure/anneal if elevated-temperature service is needed.
What surface finishes work on Digital ABS?
Sands and primes readily; paint or clear-coat for UV protection, and vapour-free wet sanding gives a near-injection-moulded finish before electroplating for cosmetic models.

Digital ABS HT — frequently asked
What is Digital ABS HT used for?
Digital ABS HT is typically used for functional prototypes, snap-fit housings and clips, thin-wall electronic enclosures, assembly jigs and short-run fixtures, injection mould inserts for low-volume trials and drop-test and handling samples. In short: tough ABS-emulating resin.
What is the tensile strength of Digital ABS HT?
Digital ABS HT has a typical tensile strength of 60 MPa (8.7 ksi) — stronger than 68% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Digital ABS HT easy to machine?
Reasonably — machinability is rated good (58/100, worse than 55% of polymer grades). Light drilling, reaming and tapping are practical with sharp tools and slow feeds; the crosslinked acrylic is notch-sensitive so avoid heavy cuts and keep parts cool.
Can Digital ABS HT be welded?
Not readily — weldability is rated not recommended (10/100). Not weldable (thermoset); bond with cyanoacrylate or two-part epoxy, avoid acetone-based solvent cements which craze the surface.
What surface finishes work on Digital ABS HT?
Sands and primes readily; paint or clear-coat for UV protection, and vapour-free wet sanding gives a near-injection-moulded finish before electroplating for cosmetic models.
Can Digital ABS HT be formed, bent or molded?
Shape is fixed by PolyJet jetting/UV cure — design for 0.6 mm minimum wall (1.2 mm for load-bearing), remove SUP70x support fully, and post-cure/anneal if elevated-temperature service is needed.
What is the maximum service temperature of Digital ABS HT?
Digital ABS HT is rated for continuous use to about 80°C (176 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
