ABS

An ABS prototype has up to 80% of the strength of injection moulded ABS meaning that it is extremely suitable for functional applications.

ABSi

ABSi is an ABS type with high impact strength. The semi-translucent material used to build the FDM parts is USP Class VI approved.

ABS-M30

ABS-M30 is 25-75% stronger than the standard ABS material and provides realistic functional test results along with smoother parts with finer feature details.

ABS-ESD7

ABS-ESD7 is a durable and electrostatic dissipative material suited for End-use components, Electronic products, Industrial equipment and Jigs and fixtures for assembly of electronic components.

PC-ABS

PC-ABS is a blend of polycarbonate and ABS plastic which combines the strength of PC with the flexibility of ABS.

What is meant by Fused Deposition Modeling (FDM)?

                    The system operates in X, Y and Z axes, drawing the model one layer at a time. This process is similar to how a hot glue gun extrudes melted beads of glue. The temperature-controlled extrusion head is fed with thermoplastic modeling material that is heated to a semi-liquid state. The head extrudes and directs the material with precision in ultrathin layers onto a fixtureless base. The result of the solidified material laminating to the preceding layer is a plastic 3D model built up one strand at a time. Once the part is completed, the support columns are removed and the surface is finished.

What is meant by Laser Sintering: a 3D Printing Technology?

                             Selective Laser Sintering is also a technique by which parts are built layer by layer. The basic material consists of powder with particle sizes in the order of magnitude of 50 µm. Successive powder layers are spread on top of each other. After deposition, a computer-controlled CO₂ laser beam scans the surface and selectively binds together the powder particles of the corresponding cross section of the product. During laser exposure, the powder temperature rises above the glass transition point after which adjacent particles flow together. This process is called sintering.

what is meant by Polyjet 3D printer?

  Polyjet: a 3D Printing Technology

Objet’s patented PolyJet inkjet technology works by jetting state-of-the-art photopolymer materials in ultra-thin layers (16µ) onto a build tray layer by layer until the part is completed. The intuitive Objet studio™ software manages the process.
Each photopolymer layer is cured by UV light immediately after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing. The gel-like support material, which is specially designed to support complicated geometries, is easily removed by hand and water jetting.

More Process Info of stereolithography?

Most SLA machines can produce parts with a maximum size of     20” x 20” x 24”.

  Producing parts through stereolithography can take anywhere fro a few hours to more than a day. It depends on the size and complexity of the product.

How Does Stereolithography Works?

• 
  
•       Stereolithography is an additive fabrication process utilizing a vat of liquid UV Curable photopolymer “resin” and a UV laser to build parts a layer at a time.
• 
  
•        On each layer, the laser beam traces a part cross-section pattern on    the surface of the liquid resin.
• 
  
•         Exposure to the UV laser light cures, or, solidifies the pattern traced    on the resin and adheres it to the layer below.

What is Stereolithography?

                   

Stereolithography, also known as 3-D layering or 3-D printing, allows you to  create solid plastic, three-dimensional (3-D) objects from CAD drawings in a matter of hours.

              

                         “Stereolithography is a common  rapid manufacturing and rapid prototyping technology for producing parts with high accuracy and good surface finish. A device that performs stereolithography is called an SLA or Stereolithography Apparatus.”

Nature of Carbon Fiber Reinforced PLA?

Proto-Pasta Carbon Fiber reinforced PLA is made from NatureWorks 4043D PLA Resin compounded with 15% by weight Tenax short chopped Carbon Fibers. It is designed to be stiff, or to resist bending. It is the stiffest material we offer and makes parts with an incredibly solid feel. When printed, this material is a dark glossy black that glitters slightly in direct light from the fine chopped fibers reflecting the light.

Nature of Bronze PLA Filament?

BronzeFill is a PLA/PHA based compound mixed with 80% fine bronze powder. The material is four times heavier than standard PLA. It has a density of approx 4 gr/cc (cubic centimeters) and feels like real metal. Bronzefill can be polished to get the beautiful metallic sheen as all other solid bronze products. After polishing, the normal visible layer lines disappear and the bronze object begins to stand out. ColorFabb says it will start doing intensive material tests in the next two months. Meanwhile they are looking for alternative methods to polish delicate printed parts in the easiest and most effective way.

Nature of Laywood?

Laywoo-D3 (LayWood) is a wood based filament that can be used in most desktop 3D printers. The wood filament prints easily, similar to PLA, and has a wood smell when printing.

The material has shown no warping tendencies when printed on a heated bed during testing. Possible extrusion temperature is fairly wide with a good starting point at 180C. Hotter temperatures will extrude a darker filament; using variable temperatures during a print, a faux wood ring pattern can be generated. Finished prints can also be easily sanded.

In general, if you have printed with PLA you should be able to quickly start printing with the Laywoo-D3 filament. This 3mm diameter filament comes in a 0.25kg coil and has a cherry wood color.
