FDM (fused deposition modeling) is a method of printing that uses material extrusion as additive manufacturing. Material is extruded through a heated nozzle and joined together in layers to form 3D objects.

Using polymer-based filament, FDM printing is the simplest way to create 3D prints. Easier than resin printing, and cheaper than powder-based 3D printing methods.

• Pros
  • Affordable
  • Rapid manufacturing
  • Large selection of colors and materials
• Cons
  • PLA can be low in strength and has a low melting point of 200°C

Stereolithography (SLA) is a method of printing that uses curing layers of a photopolymer (a light-sensitive liquid plastic) to create a part or object. The model is sliced into layers and each layer of photopolymer is exposed to a UV (ultraviolet) laser that immediately cures, or hardens it.
These layers are built on top of each other to form a 3D object.

Using acrylic-based, liquid plastic material, SLA printing is able to produce very precise models with high detail, and with geometry impossible for FDM printers.

• Pros
  • High definition details
  • Ideal for figurines and D&D models
  • Ideal for painting
• Cons
  • More expensive that FDM printing
  • Difficult to produce bulk orders

Computer-aided design (CAD) is a method of creating 3D models using 2D drawings. Fusion360 and Solidworks are the two primary softwares that we use in our workflow.

Files can be delivered a variety of formats, with .stl being the primary format.
