All About Creating Plastic Prototypes With 3D Printing
Almost every time a company creates a new product, no matter the industry, they need to create a prototype model to evaluate the design. The model can be used to check form and function, to gather customer or investor reaction, or to assess unique properties of the part. Rapid prototyping is one of the more affordable and straightforward means to create a plastic prototype. Many plastic prototype companies will use 3D printing, one type of rapid prototyping, for this process.
How Does 3D Printing Work?
3D printing is also
known as additive manufacturing. That is a common term that covers many
different technologies in which material is added to build a part (rather than
removed, as in machining). Three popular methods include Selective Laser
Sintering (SLS), Fused Deposition Modeling (FDM), and Stereolithography (SLA).
SLS technology involves using nylon in powder form. This technique uses a laser
to fuse the powder into the part. When the laser is done, the part is lifted
out of the remaining cake of unsolidified material. SLS plastic prototype
service yields a finished prototype that is durable, flexible, and can be
finished to represent a part that may be injection molded in production
situations. With FDM 3D printing, the machine uses an extrusion process to melt
plastic filament and build the object layer-by-layer. While some FDM machines
are meant for the hobbiest, plastic prototype companies will use
industrial-level printers to create prototypes in a high resolution. You can
choose from several different kinds of materials, depending on the end use
intended for the part. With SLA 3D printing, the plastic prototype manufacturer
will use plastic resin materials in a liquid form that are solidified
layer-by-layer to make your prototypes. This is a widely used process,
particularly for consumer goods, medical products, and dental products.
