and individuals have only just begun to discover the many ways that DDM can positively impact manufacturing. As DDM adoption increases and the application envelopes are expanded, industry will discover more uses for and more advantages from DDM.
The opportunities seem boundless. In fact, any limits that arise seem to be self-imposed. The implementation and advantages are limited only by our creativity, imagination and innovation. DDM is a radical departure from tradition. It is a revolutionary process, so open minds are needed. DDM is in its earliest stages, and there are many advancements waiting for us in the future. It is easy for opponents and critics to shoot down DDM when pitted against and established manufacturing method.
DDM is a revolution that will initially be built in an evolutionary way. To establish a foothold, it will start with incremental gains and niche applications. The full revolution is not here yet. For it to take place, improvements and advancements are needed in areas such s technology, equipment, materials and science. To facilitate the coming revolution, industry also needs more education.
Yet, DDM is viable today. Every day, companies are taking steps toward this future, and they are receiving immediate benefits. It will take time for the full revolution to occur; it will require agents of change; and it will demand open mindedness for industry to move towards the new reality in manufacturing. Direct digital manufacturing will deliver fundamental changes and sweeping advantages.
FDM PROCESS DESCRIPTION
Fortius 3D Production Systems are based on patented Stratasys FDM (Fused Deposition Modeling) technology. FDM is the industry's leading Additive Fabrication technology, and the only one that uses production grade thermoplastic materials to build the most durable parts direct from 3D data. Fortus systems use the widest range of advanced materials and mechanical properties so your parts can endure high heat, caustic chemicals, sterilization, high impact applications.
The FDM process dispenses two materials—one material to build the part and another material for a disposable support structure. The material is supplied from a roll of plastic filament on a spool. To produce a part, the filament is fed into an extrusion head and heated to a semi-liquid state. The head then extrudes the material and deposits it in layers as fine as 0.005 inch (0.127 mm) thick.
Unlike some Additive Fabrication processes, Fortus systems with FDM technology require no special facilities or ventilation and involve no harmful chemicals and by-products.
