Cutting Edge Engineering & Design

With the invent of 3D Printing comes SLA printing, and 3D fff printing to this wonderful world of engineering and design.  Does this all sound like a foreign language to you?  Not to worry.

3D SLA Printing is just “Stereolithograpghy” – laser design printing.  This is basically a rapid prototyping or rapid 3D production process.  It entails a 3D printing machine converting liquid resin into solid objects.  It is a layer by layer process that produces three-dimensional solid models, prototypes and patterns that can be beneficial in medical modeling, product part recreation, and much more.

3D FFF Printing is a 3D printing process that uses a continuous filament of thermoplastic material.  This is fed from a large coil, through a moving, heated printer extruder head.  Molten material is forced out of the print head’s nozzle and is deposited on the growing workpiece.  See Wikipedia  Also very useful in many different industries for reverse engineering products.

Basically, the real difference is…

SLA 3D Printing uses a “liquid” resin cured by ultraviolet laser.

And,

FFF Printing extrudes molten plastic through a nozzle and allowing materials to cool and bond together before the next layer is deposited.
