Rapid Prototyping Overview

Tenere's rapid prototyping division has provided customers with fast prototypes since 1990.  Whether you need a quick part to check fit, a painted appearance model for photo shoots or low volume production parts, we have a process and finish in house to meet your needs.

With all our plastic services in one location, prototyping with Tenere gets you quick and easy transition into plastic injection molding.


“The parts are high precision, [and] have really tight tolerances.  Frankly they helped us speed up our development in a lot of ways.”


Stereolithography (SLA) - Using a 3D model, our stereolithography machine and its operator mathematically create a series of cross-sections (layers) to guide the path of an ultraviolet laser. The laser then traces each layer across a vat of photo-curable liquid polymer, changing the liquid into a solid.  After each layer, a re-coating and leveling system establishes the thickness of the next layer.  The part is built layer by layer, until a three-dimensional part is formed.

Laser Sintering -Laser Sintering (LS) is a process that uses a laser beam to selectively melt a heated powder.  The build starts off with about .400" of material in the vat.  Once the building of parts has started, a .005" layer of powder is spread across the build platform and the next layer is melted onto the previous layer.   This continues until the build is complete.   The material that is not selectively melted acts as support for the part itself.  This process has the ability to build in X, Y and Z so parts can be stacked on top of each other which allows for more parts to be built in a single run.   When the build is complete the material in the vat needs to cool down.  Once the vat has cooled down, the parts must then be excavated from the block of powder.  They are then cleaned and blasted to remove as much excess powder as possible.  Once this is done the parts are ready to ship.

Objet 3D printing is a process where print heads lay down material on a platform layer by layer until a part is created. With each pass from the print heads, material (both support and model) is laid onto the platform or previous layer and cured via UV light, making it one of the fastest options for creating parts.  The support material covers the outside of the part and also supports any overhanging sections on the part.  Once the build is complete, the part is removed from the platform and the support material is cleaned off using mechanical tools and pressurized water.

Fused Deposition Modeling (FDM) builds parts by heating material that gets fed through a print head after reaching a semi liquid state.  It builds each part layer by layer adding support material where needed.  Each layer is determined during setup where a program creates a path to build the part.  Once a layer is complete the base moves down so the next layer can be added.  Each layer is added until the program is complete and parts are ready to be removed from the machine.  Support material is removed by breaking away the tiny pieces or placing the part in a water/detergent mix that dissolves the support material.

3D printing orders today can often ship tomorrow because of our large fleet of machines. 


Freedom to experiment with multiple iterations of the same part in a short amount of time. 


Proving your design before moving to hard tooling saves you time and money.
