What is PC-Like GREEN?
PC-Like GREEN is PC-Like in the GREEN condition — state straight off the printer after wash — use only for visual mock-ups; strength and Tg are well below cured values and creep is severe. PC-Like GREEN has a yield strength of 30 MPa (4.35 ksi) and a tensile strength of 36 MPa (5.22 ksi) — weaker than 89% of polyurethane grades. Elongation at break is 12% and the elastic modulus is 1.7 GPa (0.247 Msi). PC-Like GREEN has a density of 1.16 g/cm³ (0.0419 lb/in³), heavier than 74% of polyurethane grades. Its glass-transition temperature is 48°C (118 °F).

Working with PC-Like GREEN
Is PC-Like easy to machine?
Drills, taps and mills cleanly with sharp carbide and light feed, but run dry-ish and slow — heat above Tg smears the surface and edges chip.
Can PC-Like be welded?
Not weldable; join with cyanoacrylate, two-part epoxy or by re-curing fresh resin at the joint under UV.
Can PC-Like be formed, bent or molded?
Vat photopolymerisation only — print at 25–100 µm layers, drain and wash in IPA/TPM, then UV post-cure with heat (typically 60–80 °C, 15–60 min) to reach datasheet properties; allow 0.15–0.5 % cure shrinkage and support thin walls to limit warp.
What surface finishes work on PC-Like?
Sand 400→2000 grit and either clear-coat or vapour-polish-free lacquer for optical clarity; primers and 2K automotive paint adhere well, and clear parts should get a UV-blocking topcoat to slow yellowing.
PC-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.

PC-Like GREEN — frequently asked
What is PC-Like GREEN used for?
PC-Like GREEN is typically used for impact guards, functional housings, clear lamp covers and light guides, assembly and fit verification parts, small-batch functional prototypes and machine guards and windows. In short: highest impact of the rigid PUs; PC-like stiffness.
What is the yield strength of PC-Like GREEN?
PC-Like GREEN has a typical yield strength of 30 MPa (4.35 ksi) and a tensile strength of 36 MPa (5.22 ksi) — weaker than 89% of polyurethane grades. Strength varies by condition: see the 5 listed tempers.
Is PC-Like GREEN easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 76% of polyurethane grades). Drills, taps and mills cleanly with sharp carbide and light feed, but run dry-ish and slow — heat above Tg smears the surface and edges chip.
Can PC-Like GREEN be welded?
Not readily — weldability is rated not recommended (5/100). Not weldable; join with cyanoacrylate, two-part epoxy or by re-curing fresh resin at the joint under UV.
What surface finishes work on PC-Like GREEN?
Sand 400→2000 grit and either clear-coat or vapour-polish-free lacquer for optical clarity; primers and 2K automotive paint adhere well, and clear parts should get a UV-blocking topcoat to slow yellowing.

What is the maximum service temperature of PC-Like GREEN?
PC-Like GREEN is rated for continuous use to about 40°C (104 °F), and briefly to 85°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
