At ProtoCAM, we’re committed to educating our rapid prototyping and additive manufacturing customers.
Additive manufacturing is made up of several technologies. It is often difficult to understand how a technology works before you see it in action. We hope the videos on the page below provide a visual understanding of the technologies involved.
Additive Manufacturing Processes:
- Stereolithography (SLA)
- Urethane Castings
- Selective Laser Sintering (SLS)
- Direct Metal Laser Sintering (DMLS)
Today’s additive manufacturing technologies allows us to create highly accurate prototypes in varying levels of finish including our proprietary clear bottle finish. From applications in the aerospace industry to automotive, new technologies are constantly being used in innovative new ways.
For over 20 years we have been using the array of additive manufacturing technologies in new and innovative ways. Recently, we were even able to achieve what was once thought not possible, a clear bottle prototype.
Each of these processes allow us to create highly accurate prototypes and finished products rapidly. For more information on turnaround times for a rapid prototyping project, contact us.
Additive Manufacturing Uses:
- Stereolithography Created Clear Femur Bones
- RTV Molded – Kids Pig Toy
- Using Rigidity To Choose An Additive Manufacturing Method
Video: Stereolithography (SLA) Animation
Stereolithography / SLA is a process where a laser is used to harden a resin. The resin hardens as it comes into contact with the laser, and the new part is built-up one small layer at a time. This is a computer-generated stereolithography / SLA animation demonstrating the actions of the SLA machine.
Video: Room Temperature Vulcanization (RTV) Molding
RTV molding is a step in the urethane casting process that is often made from a stereolithography prototype. An RTV mold can be created from a sla prototype, which then allows the new part to be created production-ready in small quantities. This animation shows various steps necessary to create an RTV mold.
Video: Selective Laser Sintering (SLS)
Laser sintering is a method of additive manufacturing where various powdered nylons or A6 tool steel is used to create rapid manufactured prototypes and short-run production parts.
Video: Direct Metal Laser Sintering (DMLS)
Direct Metal Laser Sintering (DMLS) allows additively manufactured metal parts to be built in native metals. In the DMLS process, a laser fuses powdered metal granules creating fully dense metal parts, with the ability to create geometries difficult or impossible with traditional manufacturing techniques.

Stereolithography can be a cost-effective method of prototyping. A good example of using the right layout to maximize efficiency and cost saving is this sla prototype of 30 clear human bones. In many situations, additive manufacturing can provide a quick cost effective way to generate a prototype.
Video: RTV Toy Pig – Prototype
Additive manufacturing has numerous uses and as the video below shows, even for creating a toy pig.
Video: Using Rigidity To Choose An Additive Manufacturing Method
Each additive manufacturing method has unique benefits that make it best suited for particular products. In the video above we demonstrate the difference in rigidity between an Accura sla structure support and Polyjet support.
