About Us
Prototyping and Production Services
Born from a need to create a special fixture for our Circadian Lighting products, about two years ago founder Chris Dubriske expanded the LumenMesh business with 3D printing capabilities.
Today we have positioned a subsidiary of LumenMesh, Keene Additive Manufacturing, to provide complete 3D additive manufacturing design and production services to offer this exciting manufacturing services to business and individuals in need of accurate, high tech, parts and products.
Keene Additive Manufacturing, located in Keene, NH now has 8 3D printers with plans to double this capacity in the near future.
We can work from sketches, CAD drawings, physical products and sometimes just pictures of what you want. Keene Additive Manufacturing is still a start up but over the past year Chris has developed his modeling skills, design capacity and advanced design software to the point where he feels comfortable with using additive manufacturing to create almost anything.
We are looking for production and prototyping business and can react quickly to your needs.
Review some of the products we have done to date and the special printing techniques used on them to get a feel of what can be done.
Featured Projects
The long fin like piece is a watertight float printed using a new type of filament that is both water and UV proof. This 3D printing filament, known as ASA, was designed by Dupont to print a pedestrian bridge and it works perfectly in this exterior application.
Here you see parts that were made to convert a consumer product from the need for injection molds. This is a major step eliminating the need for costly molds but more importantly it allows the product manager to tweak and redesign parts for a better product. Additive Manufacturing at its best!
The black and red hub is an engineering feat that cannot be duplicated by any other manufacturing method including multiple axis CNC milling. 3D printing can unlock a lot of design possibilities!
Here is an example of a very challenging product to make. This was 3D printed to show the unique products that can be created with additive manufacturing.
Here you see two printed pieces with added material
Lead being added mid-print to increase strength and weight.
Metal ring inserted here during the print to significantly reduce assembly time
End product, showing a multi-color logo as well.
Tight Tolerances
These small pieces are example of holding fine tolerances as well as creating a piece with movable parts.
That’s right you can print products that are actually multiple parts, all printed at the same time but independent of each other allow movement
3D Printing technology
The Additive Manufacturing Industry
At Keene Additive Manufacturing we focus on the process of FDM (fused deposition modelling) printing. By extruding spools of plastic through a nozzle at close to 500 degrees Fahrenheit we are able to create extremely complex geometries.
There have been significant advancements in the materials science associated with additive manufacturing in the past decade, currently our favorite material to print with is ASA, which is an alternative to the commonly used ABS plastic. With improved UV resistance as well as a cleaner finish when compared to ABS, ASA (Acrylonitrile styrene acrylate) is a great choice for most applications where strength and weathering are a concern. Other advancements in material include Carbon-Fiber infused Nylon, otherwise known in the additive industry as "black aluminum", because of its mechanical properties that rival aluminum, this is a great application for fixtures or jigs in a manufacturing environment, reducing production time.
There are several different materials to choose from when designing a product, at Keene Additive we can go through the design process for you to determine the material that fits best based on the mechanical properties, as well as cost and production time.
Our production capabilities include build volumes from to 14"x10"x10" to 12"x12"x24", also we have a conveyor belt style printer for printing extremely long pieces. As our capabilities and operations expand we look forward to adding machines that are capable of printing in metal. The opportunities to create metal components with little waste and reduced turn around time will go a long way to improve global supply chains.
