Tough resin: SLA detail that survives being used
Standard resin's beautiful, brittle nature meets its fix here. Tough resin borrows ABS's resilience — it flexes under stress and springs back — while keeping the fine features and smooth skin that make SLA worth choosing in the first place.
Made for functional SLA
Snap-fit enclosures you'll open and close a hundred times during development; press-fit assemblies; clips, housings and jigs with fine features FDM can't hold; device prototypes that must survive a demo table full of curious hands.
It's the bridge material between looks-like and works-like: one print can audition for both roles, which shortens more prototype cycles than any spec sheet suggests.
Placement in the lineup
Under sustained heavy load or hostile chemistry, SLS nylon still rules; for pure display crispness at lower cost, standard resin is the saner spend. Tough resin owns the wide territory in between — detailed and durable, priced like the engineering material it is.
