2. Stereolithography (SLA)
3. Selective Laser Sintering (SLS)
4. Multi Jet Fusion (MJF)
5. Selective Laser Melting (SLM)

1. Fused Deposition Modeling (FDM)

FDM is the most affordable 3D printing technology, perfect for creating prototypes or functional parts. FDM printers use a spool of thermoplastic material, which is heated and then extruded layer by layer to create the desired shape. RexRoi offers a range of materials for FDM printing:

  • PLA (Polylactic Acid) is a biodegradable material that is perfect for creating eco-friendly products.
  • PLA+ (Polylactic Acid Plus) is a stronger and more durable version of PLA that is perfect for creating functional parts.
  • ABS (Acrylonitrile Butadiene Styrene) is a strong, durable material that is perfect for creating functional parts.
  • ASA (Acrylonitrile Styrene Acrylate) is weather-resistant and ideal for creating outdoor or automotive parts.
  • PETG (Polyethylene terephthalate glycol) is a strong, transparent material that is perfect for creating containers, bottles, and food packaging.
  • TPU (Thermoplastic Polyurethane) is a flexible material that is perfect for creating phone cases, shoe soles, and other flexible products.
  • Wood PLA is a combination of PLA and wood particles that create a wood-like finish and is perfect for creating wooden products.
  • Silk PLA is a material that creates a shiny, silk-like finish and is perfect for creating decorative products.
  • Marble PLA is a combination of PLA and marble particles that creates a marble-like finish and is perfect for creating decorative products.

 

Ideal Application: FDM technology is ideal for creating functional parts, prototypes, and low-cost production runs.

2. Stereolithography (SLA)

SLA is a high-precision 3D printing technology that uses a liquid resin that is cured with a UV laser. SLA printers are perfect for creating highly detailed models, jewelry, or dental applications. RexRoi offers a range of SLA materials:

  • Standard Resin is a versatile material that is perfect for creating prototypes and small-scale production runs.

     

  • Transparent Resin is a clear material that is perfect for creating clear products like lenses and light pipes.

     

  • Tough Resin is a durable material that is perfect for creating functional parts that need to withstand stress and wear.

     

  • Castable wax Resin is a material that can be used to create detailed jewelry models that can be cast in metal.


Ideal Application: SLA technology is ideal for creating high-precision models, jewelry, dental applications, and other applications that require high accuracy and detail.
