Our Metal 3D Printing Technology

Protosoon’s metal 3D printing service is based on SLM and DMLS technology. They are often considered superior for many industrial applications. For industries requiring high precision, strength, and design flexibility, SLM and DMLS are the go-to solutions, delivering performance and innovation in metal manufacturing.
Our industrial-grade metal 3D printing service provides 20+ material options such as titanium/aluminum/stainless steel, with ±0.2mm accuracy, suitable for aerospace/medical/automotive parts manufacturing. Upload CAD files to get instant quotes.

Precision and Complexity

SLM excels at pro­duc­ing high­ly detailed and com­plex geome­tries with excel­lent sur­face fin­ish­es, mak­ing them ide­al for aero­space, med­ical implants, and high-per­for­mance engi­neer­ing parts.

Wide Material Compatibility

SLM sup­ports a wide range of met­al alloys, includ­ing tita­ni­um, alu­minum, stain­less steel, and nick­el-based super­al­loys, offer­ing flex­i­bil­i­ty for diverse indus­tries.

Mechanical Properties

Parts pro­duced via SLM have near-full den­si­ty and mechan­i­cal prop­er­ties com­pa­ra­ble to tra­di­tion­al­ly man­u­fac­tured com­po­nents, ensur­ing strength and dura­bil­i­ty.

Minimal Post-Processing

Unlike binder jet­ting or met­al extru­sion, SLM parts often require less post-pro­cess­ing, as they are already near-net-shape and ful­ly dense straight after the print­ing process..

Rapid Prototyping and Customization

These tech­nolo­gies allow for quick iter­a­tion and cus­tomiza­tion, mak­ing them per­fect for pro­to­typ­ing and pro­duc­ing bespoke parts with­out the need for expen­sive tool­ing.

AlSi10Mg is a wide­ly used alu­minum alloy in 3D print­ing, par­tic­u­lar­ly in SLM and DMLS process­es. It is com­posed of alu­minum (Al), sil­i­con (Si), and mag­ne­sium (Mg), with sil­i­con con­tent around 10% and mag­ne­sium con­tent typ­i­cal­ly less than 1%. This com­bi­na­tion pro­vides excel­lent mechan­i­cal prop­er­ties, good ther­mal con­duc­tiv­i­ty, and light­weight char­ac­ter­is­tics, mak­ing it ide­al for appli­ca­tions in aero­space, auto­mo­tive, and indus­tri­al sec­tors.
