Rapid Prototyping CNC Machined Prototypes CNC Machined Prototypes-01 CNC Machined Prototypes-02 CNC Machined Prototypes-03 SLA & SLS Rapid Prototypes SLA&SLS prototypes are ideal for rapid, one-off prototypes. SLA prototyping is a process whereby a laser manufacturing process to SLA, but SLS uses a much higher powered laser to bond plastic powder together to form a 3D prototype. SLA-02 SLS-0
