What is FDM 3D Printing?
Fused filament fabrication (FFF), also known as fused deposition modeling or called filament freeform fabrication, is a 3D printing process that uses a thermoplastic filament by FDM printers, which is heated to its melting point and then extruded, layer by layer, to create a three dimensional object. Objects created by FDM begin as computer-aided design (CAD) files that have been converted to a format that a 3D printer can translate.
Benefits of Fused Deposition Modeling (FDM)
Elimold uses the most advanced industrial FDM 3D printers designed to meet tolerances of +/- a single build layer thickness for the first inch and +/- .002” for every inch thereafter.
FDM printed parts are available in a variety of high-performance plastics for applications that require resistance to the elements.
Elimold can produce FDM parts with large build volumes up to 24″ x 36″ x 36″.
FDM parts do not require tooling which reduces the manufacturing lead time from weeks to days.
FDM has the highest variety of real engineered thermoplastics.
FDM is capable of producing end-use parts on-demand, increasing throughput and helping you get to market faster.
Why Use FDM For Your Parts?
Fused deposition modeling (FDM) is among the most easily accessible and recognizable additive manufacturing technologies worldwide. Available to both 3D printing hobbyists and large-volume manufacturers alike, it is known for its speed and precision in generating three-dimensional polymeric structures using a choice of feedstock materials. The range of filaments available for fused deposition modeling include:
- Acrylonitrile butadiene styrene (ABS-M30, ABS-M30i, ABSi)
- Acrylonitrile styrene acrylate (ASA)
- Polycarbonates (PC, PC-ABS and PC-ISO)
- High-performance plastics (PPSF, Ultem 1010, Ultem 9085, and Nylon-12)
What materials can an FDM 3D printer print?
The 3D printing materials used for Fused Deposition Molding are thermoplastic polymers, coming in a filament form. Many different materials exist for this type of printing process. It varies between the industrial versus the consumer version. The plastic used in FDM filaments are generally ABS (Acrylonitrile Butadiene Styrene), PLA (Polyactic Acid) and Nylon (Polyamide), but other exotic varieties of materials can also be used, like a material blend of plastic and wood or carbon
Unlike ABS, PLA is biodegradable and is popular due to it being non-toxic. There are also dissolvable materials such as PVA which are used for support. But with this 3D printing technology, it is also possible to use some engineering materials (PA, TPU, and PETG) and also some high-performance thermoplastic materials (PEI or PEEK).
Our FDM manufacturing standards
We manufacture your parts according to strict manufacturing standards. A verification of these requirements is included in our inspection report that is shipped with every order.
- Desktop FDM: A dimensional accuracy of ± 0.5% with a lower limit of ± 0.5 mm (± 0.020″).
- Industrial FDM: A dimensional accuracy of ± 0.25% with a lower limit: ± 0.25 mm (± 0.010″).
- Consistent surface finish with no bumps or delamination. Marks left by retraction and layer changing are acceptable.
- All support material is removed such that the supported surface has a consistent finish.
- All parts are printed with 3 outline / perimeter shells or a wall thickness of 1.2 mm.
