What is ABS-Like-HT?
ABS-Like-HT is ABS-Like heat treated to HT — use for parts seeing hot air, near-motor housings, paint-bake or short thermal excursions above 80 °C. ABS-Like-HT has a yield strength of 45 MPa (6.53 ksi) and a tensile strength of 62 MPa (8.99 ksi) — weaker than 65% of polyurethane grades. Elongation at break is 5% and the elastic modulus is 2.9 GPa (0.421 Msi). ABS-Like-HT has a density of 1.16 g/cm³ (0.0419 lb/in³), heavier than 76% of polyurethane grades. Its glass-transition temperature is 115°C (239 °F). STD is the default condition FabDigit quotes; HT is available on request or by drawing note.

Working with ABS-Like-HT
Is ABS-Like easy to machine?
Drills, taps and sands easily with sharp tools and low heat, but is notch-sensitive — pre-drill pilot holes, use light feeds and avoid clamping thin cured sections.
Can ABS-Like be welded?
Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a drop of the same UV resin cured with a 405 nm lamp.
Can ABS-Like be formed, bent or molded?
Printed on 385/405 nm SLA/DLP/LCD at 25–35 °C vat temperature, then IPA-washed and UV/heat post-cured (typically 5–30 min at 40–60 °C) to reach datasheet strength; design 2 mm minimum walls and add drain holes for hollow parts.
What surface finishes work on ABS-Like?
Sands from 400 to 2000 grit and takes primer, spray paint, vacuum metallizing or electroplating well; always prime or clear-coat with UV blocker since bare parts yellow and embrittle in sunlight.
ABS-Like chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

ABS-Like-HT — frequently asked
What is ABS-Like-HT used for?
ABS-Like-HT is typically used for consumer housings, drop-test prototypes, appearance and cosmetic models, assembly fit-check parts, covers and bezels and control-panel prototypes. In short: tough and impact-resistant; mirrors molded ABS.
What is the yield strength of ABS-Like-HT?
ABS-Like-HT has a typical yield strength of 45 MPa (6.53 ksi) and a tensile strength of 62 MPa (8.99 ksi) — weaker than 65% of polyurethane grades. Strength varies by condition: see the 7 listed tempers.
Is ABS-Like-HT easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 74% of polyurethane grades). Drills, taps and sands easily with sharp tools and low heat, but is notch-sensitive — pre-drill pilot holes, use light feeds and avoid clamping thin cured sections.
Can ABS-Like-HT be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a drop of the same UV resin cured with a 405 nm lamp.
What surface finishes work on ABS-Like-HT?
Sands from 400 to 2000 grit and takes primer, spray paint, vacuum metallizing or electroplating well; always prime or clear-coat with UV blocker since bare parts yellow and embrittle in sunlight.
Can ABS-Like-HT be formed, bent or molded?
Printed on 385/405 nm SLA/DLP/LCD at 25–35 °C vat temperature, then IPA-washed and UV/heat post-cured (typically 5–30 min at 40–60 °C) to reach datasheet strength; design 2 mm minimum walls and add drain holes for hollow parts.
What is the maximum service temperature of ABS-Like-HT?
ABS-Like-HT is rated for continuous use to about 100°C (212 °F), and briefly to 150°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ABS-Like-STD and ABS-Like Tough?
STD is the default condition — default choice for appearance models, fit-check parts and general functional prototypes at room temperature. Tough: pick when snap-fits, clips, thin walls or drop-test parts need real ductility instead of brittle fracture. Yield strength is 45 MPa in STD versus 40 MPa in Tough.
