Ra 0.8 to 3 um on top face, Ra 10 to 20 um at glued joints

Visible bond seams on presentation surfaces

SLA as-built Ra sits at 0.8 to 3 micrometres on top faces and 2 to 6 micrometres on walls, but a glued joint usually reads Ra 10 to 20 micrometres locally because of adhesive fillet and sanding scars, so presentation-grade surfaces need manual rework along every seam.[9]

Desktop SLA runs IT7 to IT9 on 100 mm; assembly error compounds across 3 to 8 interfaces

Fit-up error across glued assemblies

Desktop SLA holds IT7 to IT9 on a 100 millimetre datum, but stacking four prints across a mating plane accumulates position error because each part carries its own orientation and post-cure shrinkage history.[10]

10 to 60 minute post-cure cycles per section; helmet shell in 4 pieces = 4 cures plus 3 bonds

Time-to-cure on thick-wall parts

Formlabs specifies post-cure cycles of 10 to 60 minutes on desktop stations, and chamber size caps the cure volume, so a helmet made from four bonded shells is cured four times and bonded three times before it is usable.[11]

Build-plate flatness tolerance around 0.1 mm across 300 to 400 mm span on Form 4L and Peopoly Forge

Build-plate flatness and peel forces at 300+ mm

Inverted vat geometry puts the full cross-section under peel load on every layer, and effective build-plate flatness for Form 4L and Peopoly Forge sits on the order of 0.1 millimetre across the full platform, a tolerance small SLA machines do not have to honour over that span.[1]

USD 425 to USD 70 per print (~83% lower); 7 to 3 day lead time; 3-month payback

Black Diamond Equipment

Outdoor sports equipment · USA · 2020 · Formlabs Form 3L

Black Diamond moved climbing-helmet prototyping from an outsourced industrial SLA provider to an in-house Form 3L, iterating shell geometry and vent cutouts directly from CAD and post-curing full-size shells on a Form Cure L.[15]

Up to 70% shorter build time for large presentation models

Zaha Hadid Architects

Architecture · UK · 2019-2022 · Formlabs SLA and Massivit gel-dispensing

Zaha Hadid Architects runs a mixed fleet pairing Formlabs SLA for detailed presentation models with Massivit for very large geometry; complex organic surfaces that used to require weeks of CNC machining and hand finishing now turn around in days.[26]

6+ prototype cycles per product per year versus 2 under prior tooling workflow

Decathlon SportsLab

Consumer sporting goods · France · 2020 · HP Multi Jet Fusion + Formlabs SLA

Decathlon's SportsLab uses SLA for ergonomic, visual and surface-sensitive prototypes of bike grips, climbing holds and goggles; large-format resin handles one-piece mock-ups that previously needed a tool or multi-part bonding.[27]
