Stainless Steel

Stainless steel is printed by fusion or laser sintering. There are mainly two possible technologies that could be used for this material. It could be DMLS or SLM technologies. Since stainless steel is all about strength and detail, it is perfect for use in miniatures, bolts, and key chains.

  • 6.1.4.6.1 Distinct Characteristics
  • • Stainless steel can be heat treated to improve strength and hardness.
  • • It works well in high strength applications.
  • • It provides a strong resistance to corrosion.
  • • Ithashigh ductility.
  • 6.1.4.6.2 Disadvantages
  • • Building time for 3D printing using these metals is much longer.
  • • Stainless steel printing is expensive.
  • • The size of printing is limited.

Titanium

Titanium is the strongest and lightest 3D printing material. It is used for a process called direct metal laser sintering. This metal is mainly used in high-tech areas such as space exploration, aeronautics, and the medical industry.

  • 6.1.4.7.1 Distinct Characteristics
  • • This offers greater flexibility and design resolution.
  • • It gives production accuracy to industrial designers.
  • • It has an average roughness of the surface.
  • • Titanium is also biocompatible and resistant to corrosion.
  • 6.1.4.7.2 Disadvantages
  • • 3D titanium printing is expensive.

Ceramics

Ceramics is one of the latest technologies used in 3D printing. Glass is more durable than metal and plastic as it can withstand intense heat and pressure without cracking or warping. Therefore, this type of material is not susceptible to corrosion like other metals or wears away like plastics. This material is commonly used in binder jetting, SLA (stereolithography), and DLP (digital light processing) technologies.

  • 6.1.4.8.1 Distinct Characteristics
  • • It has high-precision components with a smooth, glossy surface.
  • • It also has resistance to acid, heat, and lees.
  • • It has a wide range of colors.
  • 6.1.4.8.2 Disadvantages
  • • Ceramics require a high amount of temperature to melt.
  • • This is not appropriate for glazing and cooking processes.
  • • Since it is fragile, it has limitations on printing objects with enclosed and interlocking parts.
  • • It is not suitable for the assembly of pieces.
