Hvskang offers top quality stereolithography (SLA) and selective laser sintering (SLS) prototyping services.
Hvskang manufactures SLA prototypes using DSM Somos 14120, which closely simulates ABS thermoplastic and produces strong, water-resistant prototypes. Our SLA models are primarily used as master patterns to produce silicone rubber molds for vacuum casting of polyurethane.
SLS prototyping is a similar manufacturing process to SLA, but SLS uses a much higher power laser to bond plastic powder together to form a 3D prototype. Typically, selective laser sintering uses Polyamide (Nylon). It is also possible to use glass-filled nylon in SLS prototyping.
Tolerances
SLA and SLS models are typically +/- 0.1mm in X & Y and +/- 0.3mm in Z. This varies up or down for various geometries and sizes. If a customer needs a tight tolerance in a particular area, they can specify this in a 2D PDF, and we will machine or finish the part to suit.
