Photo-Catalysis in 3D Printing

3D printing technology is used to produce 3D porous structures in CaSO4 that can be later activated with an appropriate photo catalyst. TiO2 was selected as an ideal photocatalyst producing activated 3D structures than can be used to study their effectiveness in the degradation of pollutants in wastewater.

Although there are many different printers available, only nine basic types of 3D printing technology currently exist:

• Fused Deposition Modeling (FDM)
• Stereo lithography (SLA)
• Digital Light Processing (DLP)
• Selective Laser Sintering (SLS)
• Selective Laser Melting (SLM)
• Electron Beam Melting (EMB)
