Polishing
Surface result
Smoother, glossier visible surfaces where geometry allows
Best for
Improving smoothness and gloss on Maraging Steel parts used for end-use metal parts, where geometry permits.
Note
Confirm edge retention and dimensional impact on Maraging Steel; fine features may soften during polishing.
Sand Blasting
Surface result
Uniform matte texture
Best for
Creating a uniform matte texture on Maraging Steel parts used for end-use metal parts and display or functional prototypes.
Note
Confirm masking and feature retention on Maraging Steel; abrasive blasting can change texture and soften fine details.
Laser Engraving
Marking result
Permanent text, logo, or identification marking
Best for
Adding permanent text, logos, or identification to Maraging Steel parts used for end-use metal parts.
Note
Confirm contrast, marking depth, and heat sensitivity on Maraging Steel before production.
Shot Peening
Surface effect
Compressive surface treatment for metal parts
Best for
Improving the surface condition of Maraging Steel metal parts used for end-use metal parts and load-bearing applications.
Note
Confirm alloy response, dimensional tolerance, and surface coverage on Maraging Steel; process settings affect the final surface condition.
Heat Treatment
Mechanical result
Adjusted strength, hardness, or stress-relief depending on the alloy
Best for
Adjusting the strength, hardness, or stress state of Maraging Steel parts for end-use metal parts and demanding functional use.
Note
Confirm alloy-specific cycle, dimensional change, and post-treatment requirements for Maraging Steel before production.

Aluminum (AlSi10Mg)
SLM · Silvery-gray
AlSi10Mg is a relatively soft but versatile aluminum alloy material. Thanks to its relatively low cost, excellent machinability and formability, this material is widely used in many industrial fields and is currently one of the most commonly used metals. The construction industry is the main application area for this material, followed by general engineering. AlSi10Mg exhibits excellent thermal and electrical conductivity. Its thermal conductivity is about one-half that of copper, and its electrical conductivity is about two-thirds that of copper.

316L Stainless Steel
SLM · Silvery-gray
316L stainless steel is one of the most commonly used stainless steel grades in 3D printing. Thanks to the extremely high temperature gradient and extremely fast solidification rate during the printing process, the material's mechanical properties after molding are better than traditional castings (although some printers also support printing in 17-4 PH stainless steel). 316L is a metal with strong mechanical properties. The printed surface is usually rough and has pitting (melt pool marks). The material can provide a variety of polished or matte post-processing effects and is widely used in jewelry, functional parts, small sculptures and other fields.
