The typical applications of 3D printing materials include conceptual models, validation models and rapid prototyping, which accord with ergonomic studies, visual analysis, shape and function testing, and engineering evaluation.
The category of 3D printing materials:
Different 3D printing technologies have different materials:
1. For the user, There are industrial grade and desktop grade materials.
2.In terms of physical morphology, it mainly including :liquid photosensitive resin material, thin material, low solubility wire material and powder material.
3.From the composition of various materials including: plastic, resin, wax and other polymer materials. Metal alloy materials, etc.
The Industrial-grade 3D printing materials include:Nylon, flexible and rigid photosensitive resin, heat-shrinkable ABS,PEEK,PC series engineering plastics, metal powder 3D printing soft rubber 3D printing , silica gel, transparent materials, ceramics, stainless steel, mold steel, high-temperature nickel alloy, titanium alloy,paraffinand gypsum composites, etc.
How to choose the materials of 3D printing?
1.SLA: Adopt the Light sensitive resin, milky white texture, good strength, but small toughness, easy to break. But easy to polish, electroplate and spray paint.
2.FDM: Using thermoplastic 3D printing material, the surface print layer mark is obvious, rough. But good strength, good toughness, strong solvent resistance, durability and stability and other characteristics, conducive to accurate functional testing, mold and production of finished products of the ideal material.
3.SLS: PA series material, wear resistant, high strength and stiffness, good chemical resistance. But the surface is relatively rough. There are also PA3200GF nylon fiberglass materials for deep drawing dies or any other applications requiring specific stiffness, thermal deformation, high temperature and low wear
4.DLP: Using pixel point control mask projection layering high quality high precision three-dimensional processing process. Printing precision is high, the surface is very fine, no polishing and polishing, but there are local position generated support points need to support and repair, polishing treatment. The typical application is the 3D printing of red wax figures.
5.MJP: Using wax and resin 3D printing materials, multi-nozzle jet cold light curing, can print high precision small parts. Easy removal of support material. There are different material options (including soft glue), which are typically used in the manufacturing of jewelry, precision machinery, electronic yuanqi parts, etc. Shi que and precision machinery, electronics and optical parts, the performance of which is close to that of the bulk material manufacturing.
6. DMLS,LSM and EBM electron beam melting 3D printing technology, metal printing materials are: Titanium Ti64 Titanium alloy, mold steel MS1, stainless steel GP1,17-4,316, high temperature nickel alloy IN718,625, magnesium aluminum alloy AISI10Mg, cobalt chromium-molybdenum alloy, Cobaltchrome SP2 cobalt fund ceramic alloy, bronze, precious metals (including gold).
