What is Fused Deposition Modeling (FDM)?
Fused deposition modeling (FDM) printing is a method of rapid prototyping that transforms 3D CAD data into precise physical models.
Three-dimensional (3D) prototypes are produced with strong, durable ABS plastic, providing functional prototypes to prove your design.
The FDM machine deposits a thin bead of melted ABS plastic on a flat, modeling surface which prints a cross-sectional layer of the part. Additional layers are deposited on top of the preceding layer until the prototype is complete. The machine deposits support material where necessary to support any overhanging portions of a 3D model.
The FDM machine we use is the Dimension SST which is capable of producing prototype model tolerances of 0.010" (0.25mm) along the X ,Y and Z axis. The maximum build size is 8" wide x 8" deep x 12" high. The colors we stock are black, grey and white.
How Can FDM prototypes work for me?
- Many companies have used ABS prototypes to test-market an item without incurring large up front tooling expenses.
- Engineers use ABS prototypes for form-and-fit studies, testing, and "peace of mind" before investing in costly tooling.
How long does the process take?
After a 3-D file is made and fed into the FDM machine the process is completed in just hours as compared to the days or weeks needed for most other prototyping methods.
What factors determine cost?
While the cost is a fraction of a "tooled" prototype, cost is determined by:
- Part Dimensions - larger prototypes will require more material.
- Finishing - Processes such as painting will add costs.
- Development / Design - the process begins with an STL or 3-D CAD drawing. If you submit an STL file to us that's "ready to go", your only cost will be for part material and if needed, finishing. If Sierra Pacific is involved with creating or modifying a 3-D CAD file, then additional costs will be incurred.
