Danko Arlington, Inc. is pleased to announce its entry in the exciting field of Rapid Prototyping.
The company has recently purchased a portable 7 axis Coordinate Measuring Machine with an integrated laser scanner, reverse engineering software, and a large 3D Printing System. This new equipment will enable the company’s existing Foundry, Pattern, and Machine Shop Divisions to quickly and accurately reproduce a customer supplied file or part in days as compared to weeks of standard lead time.
The portable CMM can measure parts in the shop or in the field to an accuracy of +/- .0015 inches with +/- .0011 inches of repeatability within an 8.2 foot measuring range! Points and data can then be used to make parametric computer models for copying, modifying, or enhancing an existing part’s shape. Parting lines, fillets, draft, and cores can also be developed to produce optimal casting designs.
A strong, hard plastic prototype of the new geometry can then be printed on the new machine for customer review, evaluation, and approval. 3D printing can also be used to make new or replacement foundry patterns, core sticks, or full core boxes for sand casting. For thinner walled parts, the pattern material itself can be fully invested as a quick cast used in the investment casting process.
The company will use Fused Deposition Modeling (FDM) to print ABS or high strength Poly Carbonate thermoplastic in .007″ layers for a high surface finish and accurate feature details. The printer has a huge build size of 36″ x 24″ x 36″ with accuracies of .0035″ inches or +/-.0015 inch per inch whichever is greater.
Purchased equipment includes Hexagon Metrology’s Romer 7axis 7525 SI Portable CMM and PCDMIS CAD ++ Software, Dezign Works Software by Creative Dezign Concepts, and a Fortus 900mc Production System made by the Stratasys Corporation.
Danko Arlington is proud to take our ninety year old company to the next level of fast, state-of-the-art, and efficient manufacturing. The rapid prototype technology will nicely enhance the company’s existing capabilities for many more years to come!
