What is Elastico DM-A50?
Elastico DM-A50 is Elastico heat treated to DM-A50 — mid-soft blend for seals and bellows needing more recovery force than A30. Elastico DM-A50 has a tensile strength of 4 MPa (0.508 ksi), weaker than 83% of polymer grades. Elongation at break is 130% and the elastic modulus is 0 GPa (5.08×10⁻⁴ Msi). Elastico DM-A50 has a density of 1.15 g/cm³ (0.0414 lb/in³), lighter than 59% of polymer grades.
Limitations
- Difficult to machine — 13/100, worse than 99% of polymer grades
- Absorbs moisture — dry before molding — 1.8%, worse than 95% of polymer grades
- Limited service temperature — 50°C (122 °F), worse than 94% of polymer grades
- Low stiffness — 0 GPa (5.08×10⁻⁴ Msi), worse than 92% of polymer grades
- Degrades in UV without stabilisers — 25/100, worse than 76% of polymer grades

Working with Elastico DM-A50
Is Elastico easy to machine?
Not machinable — trim flash with a fresh scalpel or die-cut; drilling/milling tears the soft matrix.
Can Elastico be welded?
Not weldable; bond with cyanoacrylate or silicone/urethane adhesive after light surface abrasion and IPA wipe.
Can Elastico be formed, bent or molded?
Built by UV material jetting at 14–27 µm layers; keep thin flexible walls ≥0.6 mm, design support removal access, and remove SUP70x support by water jet or dilute NaOH/Na2SiO3 bath.
What surface finishes work on Elastico?
Glossy up-faces need no post-work; matte parts can be lightly dyed but not polished or plated — store parts out of sunlight and expect gradual yellowing and stiffening.

Elastico DM-A50 — frequently asked
What is Elastico DM-A50 used for?
Elastico DM-A50 is typically used for clear flexible tubing mockups, soft transparent seals and wearable device prototypes. In short: clear rubber-like PolyJet resin; 245% elongation; better tear resistance than Tango.
What is the tensile strength of Elastico DM-A50?
Elastico DM-A50 has a typical tensile strength of 4 MPa (0.508 ksi) — weaker than 83% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is Elastico DM-A50 easy to machine?
Not especially — machinability is rated not recommended (13/100, worse than 99% of polymer grades). Not machinable — trim flash with a fresh scalpel or die-cut; drilling/milling tears the soft matrix.
Can Elastico DM-A50 be welded?
Not weldable; bond with cyanoacrylate or silicone/urethane adhesive after light surface abrasion and IPA wipe.
