Packaging and Precautions

Packaging according to product characteristics, or customized according to customer needs. Wear protective equipment, goggles, rubber gloves, masks, etc. when using. If accidentally contact with mucous membranes, rinse with plenty of water and seek medical attention in time.

How to Select 3D Printing Powders?

Different 3D printing equipment and forming processes require different particle size distributions. At present, the powder size range commonly used for metal 3D printing is 15-53 μm (fine powder), 53-105 μm (large particle size), and in some cases, it can be relaxed to 105-150 μm (larger particle size).

The choice of powder 3d printing particle size for 3D printing is mainly based on metal printers with different energy sources.

The printer using laser as the energy source is suitable for the use of powder of 15-53 μm as a consumable material because of its fine focusing spot, which is easy to melt fine powder, and the powder supply method is layer-by-layer powdering;

The powder-printing printer with electron beam as the energy source has a slightly focused spot, which is more suitable for melting coarse powder, and is suitable for using coarse powder of 53-105 μm;

For a coaxial powder feeding type printer, a powder having a particle size of 105 to 150 μm can be used as a consumable.

FAQs of Metal 3D Printing Powder

Q1: Can 3d printers print metal?

Yes, 3D printers can print metal objects using various techniques such as Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM), and Binder Jetting. These processes involve fusing metal powders layer by layer to form complex structures.

Q2: Who invented 3d metal printing?

The invention of 3D metal printing is attributed to several advancements over time rather than a single inventor or event. However, key milestones include the development of Selective Laser Sintering (SLS) technology in the 1980s by Dr. Carl Deckard at the University of Texas, which initially used plastics but laid the groundwork for metal sintering. The direct metal laser sintering (DMLS) process was later commercialized by EOS GmbH in the early 1990s.

Q3: How cost effective is 3d print metal?

The cost-effectiveness of 3D printing metal depends on factors like the complexity of the part, material costs, machine operating costs, and production volume. For small batch production or highly complex parts, 3D printing can be more cost-effective than traditional manufacturing methods due to reduced waste and the ability to create intricate designs without additional tooling. However, for large-scale production runs, traditional manufacturing methods may still be more economical.

Q4: How much is the investent to 3d print metal minatures?

Investment costs for 3D printing metal miniatures can vary widely depending on the type of printer, its capabilities, and the ancillary equipment needed. A professional-grade metal 3D printer can range from tens of thousands to hundreds of thousands of dollars. Additionally, there are costs associated with powder handling systems, post-processing equipment, and operational expenses (e.g., energy, maintenance, and materials).

Q5: Can I 3d print a spring with metal filament?

Using metal filament to 3D print a spring is possible but with some caveats. There are filaments available that contain a mixture of plastic (usually PLA) with metal particles, designed to give a metallic finish. However, these prints will not have the same mechanical properties as solid metal parts. They are more suitable for decorative or prototyping purposes rather than functional metal springs requiring high elasticity and strength. For a functional metal spring, you would need to use a true metal 3D printing process that melts or sinters metal powders directly.
