Understand the industry knowledge of 3D printing products
3D printing, as a revolutionary manufacturing technology, is gradually demonstrating its unique charm and enormous potential in various fields. The following is an in-depth discussion on the knowledge of the 3D printing product industry.
1, Principles of 3D Printing Technology
3D printing, also known as additive manufacturing, is based on the basic principle of creating a three-dimensional model through computer-aided design (CAD) software, and then cutting the model into a series of thin cross-sections. The 3D printer stacks materials layer by layer based on the cross-sectional information, ultimately forming a three-dimensional solid. Common 3D printing techniques include fused deposition modeling (FDM), photopolymerization modeling (SLA), selective laser sintering (SLS), and so on.
2, 3D printing materials
Plastic materials
PLA (Polylactic Acid): an environmentally friendly and biodegradable plastic with good printing performance and low shrinkage rate, commonly used for making models, prototypes, and some daily necessities.
ABS (Acrylonitrile Butadiene Styrene): It has high strength and toughness, but may produce odors during the printing process, and is commonly used to make functional parts and casings.
PETG (polyethylene terephthalate 1,4-cyclohexanedimethanol ester): Combining the advantages of PLA and ABS, it has good mechanical properties and chemical resistance.
Metallic materials
Titanium alloy: It has high strength, low density, and good biocompatibility, and is widely used in aerospace, medical, and other fields.
Stainless steel: It has good corrosion resistance and mechanical properties, and can be used to manufacture tools, molds, and components.
Aluminum alloy: lightweight and high strength, suitable for lightweight design in fields such as automobiles and aviation.
ceramic material
Aluminum oxide: It has high hardness, high temperature resistance, and good insulation properties, and can be used to manufacture electronic components, ceramic tableware, etc.
Zirconia: It has excellent mechanical properties and biocompatibility, and is commonly used in dental restorations and medical devices.
