Fused Depostion Modeling

FDM is the most common, recognizable and widely available 3D printing technology. FDM printers can build parts quickly and with a lot of strength in a range of thermoplastics at an economical cost.

FDM is a filament based technology which works by melting thermoplastic via a heated extruder. The melted plastic is then deposited onto the printers build platform one layer upon another layer. Each layer hardens and cools down instantly upon the previous layer, binding both the layers together. Support structures are created where needed or for more complex overhanging geometries.

FDM 3D printing is ideal for:

  • forward - Low Volume Production
  • forward - Protoytpes for form, fit and function testing
  • forward - Design Verifications
  • forward - Detailed Functional Prototypes
  • forward - Durable Manufacturing Tools
  • forward - Student Projects
  • forward - Gifting Solutions

Technical Specifications for FDM

forward Standard Lead time: Minimum 2 working days depending on part size, number of components and finishing requirements lead time may increase.

forward Standard Accuracy: ± 0.1mm

forward Tolerance: ± 0.4 mm

forward Layer thickness (resolution): 0.1 mm – 0.3 mm

forward Minimum Wall thickness: 1mm

forward Max dimensions: 280mm x 250mm x 300 mm. Large parts can be created by assembling individual parts by interlocking designs or glueing them together.

forward Surface finishing and Post Processing: Unfinished parts typically need to have print supports removed by hand and have a rough surface with visible layers but all kinds of finishes are possible. FDM parts can be sandblasted, smoothed, colored, painted and coated.

Materials

forward PLA (Polylactic Acid) is a biodegradable thermoplastic derived from renewable resources such ascorn starch or sugarcane. It is used for low-cost, non-functional prototyping. Offers greater detail than ABS, but is more brittle. Unsuitable for high temperature applications. Comes in a range of colors, property and finish options such as silk, glow in the dark and color change in temperature.

forward Woodfill PLA contains wood, bamboo, or cork-based pulverized material, resulting in FDM parts with a unique wood-like appearance.

forward Metalfill PLA contains steel, copper, brass, bronze or other metal particles that give parts a metallic surface finish and unique properties.

forward Ceramic PLA is food-safe, recyclable, and water-tight material which is great to use for cups, plates, statues, or figurines.

forward Marble PLA filament is used to create parts with purpose, like tools, grates, Architecture model or finishing components that require a marble texture

forward H-PLA is a biological material made from corn grain refining and natural color degradation and does not affect the environment. H-PLA is tougher than ordinary PLA. H-PLA temperature can withstand 100 ℃, ordinary PLA can only withstand 60-70 ℃. The surface finish is bright , gloss and smooth. The processing is odorless and the material does not curl or wrap during printing

forward ABS (Acrylonitrile Butadiene Styrene)has good mechanical properties, with excellent impact strength, superior to PLA, but less defined details. Commonly used for enclosure prototypes.

forward Conductive ABS is a filament that can support low-voltage circuitry. Often used for coupling circuit boards with LEDs and sensors for customized electronic projects.

forward PC- ABS (Polycarbonate - ABS) Commonly found in automotive, electronics, and telecommunications applications, it is one of the most widely used industrial thermoplastics in the world.

forward Flame Retardant - ABS is made using a premium UL94 V-0 rated ABS. This filament is ideal for applications that require UL94 V-0 self-extinguishing characteristics.

forward PetG (Polyethylene Terephthalate Glycol) is a thermoplastic material with improved mechanical properties over PLA and excellent chemical and moisture resistance.

forward PetG - Carbon Fibre is the ideal filament for anyone that desires a structural component with high modulus, excellent surface quality, dimensional stability, light weight, and ease of printing.

forward TPU is a rubber-like, flexible material that can bend and compress. Lacks the performance of true rubber.

forward HIPS(High Impact Polystyrene) typically plays a different role. 3D printers can’t print onto thin air. Overhangs require some underlying structure, and this is where HIPS really shines. When paired with ABS in a dual extrusion printer, HIPS is an excellent support material. Simply fill any gaps in your design with this 3D printer filament, then melt it away by immersing the finished product in limonene, a colorless liquid hydrocarbon.

forward PVA Polyvinyl alcohol (PVA) is soluble in water, and that’s exactly what commercial applications are take advantage of. Popular uses include packaging for dishwasher detergent “pods” or bags full of fishing bait. (Throw the bag in water and watch it dissolve, releasing the bait.) The same principal applies in 3D printing, making PVA a great support material when paired with another 3D printer filament in a dual extrusion printer. The advantage of using PVA over hips is that it can be printed with more than just ABS. Common substitutes include PLA and Nylon.

forward Ultem is an engineering plastic with good mechanical properties and exceptional heat, chemical and flame resistance. Suitable for top-end applications.
