Start with the purpose of the part
The right manufacturing process depends less on the name of the technology and more on what the part must prove. A cosmetic prototype, a durable functional part and a small production batch can require very different routes.
Before requesting a quote, define whether the priority is appearance, strength, tolerance, heat resistance, flexibility, quantity or speed.
Typical process fit
SLA resin printing is usually best for detail, surface quality and presentation models. SLS or MJF nylon is often better for functional prototypes and robust end-use plastic parts.
Metal additive manufacturing is reserved for complex metal geometry or specialized engineering parts, while vacuum casting is useful for small batches of production-like polyurethane components.
How ExactProto supports selection
ExactProto reviews the application, geometry and production target before recommending a route. For resin printing, production can be handled in-house. For selected additional processes, qualified manufacturing partners may be coordinated while ExactProto remains the single point of contact.
