Fused Deposition Modeling (FDM)

Advantages: The manufacturing system is safe and non-toxic; The process is simple, easy to operate, environmentally friendly, and does not produce garbage; Easy transportation and replacement of raw materials, and low cost; A wide variety of materials are available

Application: Printing TNT fused cast explosive

Poor accuracy; Slower speed

Sterolithography Apparatus (SLA)

Advantages: The manufacture of particularly complex shapes and particularly fine parts, high precision, and better surface quality.

Application: Propellant (50% RDX and 50% inert binder)

Using laser scanning molding, SLA process printers are more expensive, and can only form monochrome resin at a time.

Sterolithography Apparatus―Digital projection molding technology (DLP)

Advantages: High precision

Application: TNO has been studied for a propellant formulation containing 50% RDX, 25% acrylic binder, and 25% energetic plasticizer

The technology is still immature
