Additive technology allows design complexity not possible by conventional manufacturing. Parts that required welding multiple assembly pieces can now be grown as a single part. With the advancements of industrial 3D printing, repeatable products with consistent material properties can now be manufactured with automated additive manufacturing equipment.
there are manufacturing limitations to existing methods
design updates and complexity are required without adding to cost
low volumes do not justify manufacturing tools
speed to market is required
maintaining inventory is costly
Additive manufacturing starts with a digital CAD file, which is translated into triangulated surfaces as a standard tessellation language (STL) file. The STL file is then sliced into thousands of two dimensional layers. A 3D printer reads the layers as building blocks and 3D print the layers, building a three dimensional object.
Orientation refers to how and which direction a part is placed on the Additive manufacturing build platform. For example, a part may be oriented at an angle, or standing vertical. Because 3D printing builds one layer at a time, downward facing surfaces may have more ribbed lines. Certain orientations work better for curved surfaces and factor in features to counter large flat surfaces, which are not designed for additive manufacturing.
The team at Additive Engineering can help guide you to achieve the best printed outcome for your design.
Materials are fully melted by laser in the DMLM technologies, producing dense, qualify surface finish products that require minimal post-processing.
Additive Engineering utilises GE’s Concept Laser MLab 200R DMLM technology together with biocompatible titanium in the manufacture of medical implants.
A solid mass is created without liquefying it. In Direct Metal Laser Sintering (DMLS), a laser sinters each layer of metal powder just enough to adhere to produce high-resolution products with desirable surfaces.
With Selective Laser Sintering (SLS), a laser sinters thermoplastic powders to create 3D objects.
Additive Engineering utilises the EOS FORMIGA P110 Velocis with biocompatible PA2200, which has good chemical resistance and is certified for contact with foodstuffs as well as the manufacture of surgical guides.
A UV laser is selectively fired into a vat of photopolymer UV-curable resin to print 3D objects that can withstand high temperatures. Digital light processing is a similar technology.
These systems use lasers, electron beams or thermal print heads to melt fine layers of material to form 3D objects. Used in many additive manufacturing processes including direct metal laser sintering (DMLS), selective laser melting (SLM), EBM and direct metal laser melting (DMLM). Excess powder is removed from objects.
One of the most common processes. spooled polymers are extruded or drawn through a heated nozzle that moves to melt material as the bed moves vertically. Layer adhesion occurs through the use of chemical bonding agents of precise temperature control.
Similar to Material Extrusion, this is more applicable to a wide range of materials; metals, ceramics and polymers. A laser or electron beam is mounted on a five-axis arm that melts either wire ( wire arc additive manufacturing) or filament or powdered material feedstock.
The printhead selectively deposits a liquid binding agent onto a thin layer of powder of metal, sand, ceramics or composites. Process is repeated using a map from a digital design file to form the final 3D object.
A printhead moves along x, y and z axes to create 3D objects and are cured by UV light or harden as layers cool.
The nozzle sprays metal particles at high speeds and fuse upon impact with surface, creating near net shape parts that require post processing to required resolutions.
An Additive manufacturing / 3D printing process takes a 3D CAD file, slices it into 2D layers, and additively builds up a part layer by layer. 3D printing is a transformative approach to industrial production by transitioning from analogue to digital. It is the most direct way of manufacturing with digital flexibility and efficiency to manufacturing operations.
