Aluminum (AlSi10Mg) 3D Printing Service | SLM Metal Parts

Aluminum (AlSi10Mg) material at YiguProto — Aluminum (AlSi10Mg) machined or molded by YiguProto

Aluminum (AlSi10Mg) is a light, strong metal powder. We build real parts from it with SLM (Selective Laser Melting).

In SLM, a laser melts the powder layer by layer. The layers stack into a solid metal part. No mold is needed. Almost no material is wasted.

Light weight with good strength — great for brackets and housings
High heat transfer — ideal for heat sinks and heat exchangers
Complex shapes made easy — thin walls and internal channels
Finishes available: bead blasting and anodizing
One prototype or full production — no strict minimum order

Aluminum (AlSi10Mg) is a light metal powder. We turn it into real, solid parts with SLM — Selective Laser Melting. A laser melts the powder one thin layer at a time. The layers stack up until the part is complete. No mold is needed, and very little material is wasted. That makes it perfect for shapes that are hard or costly to machine.

Material: AlSi10Mg

A cast-friendly aluminum alloy made for 3D printing. It is light, strong, and prints with stable, repeatable results.

Process: SLM

Selective Laser Melting. A fiber laser fuses AlSi10Mg powder, layer by layer, into a dense metal part.

Result: Real Metal Parts

Solid, fully dense aluminum parts for prototypes or production — finished to your exact needs.

Typical reference values for AlSi10Mg printed by SLM. Final numbers can shift slightly with heat treatment and part shape.

Values are typical reference data for AlSi10Mg in SLM and may vary with heat treatment and part geometry. Tell us your needs and we will confirm exact specs.

Lightweight

High strength-to-weight ratio. Cut weight without losing strength — key for flight and vehicle parts.

Great Heat Transfer

High thermal conductivity. Ideal for heat sinks, cooling housings, and heat exchangers.

Complex Shapes

Build internal channels and lattices. Merge many parts into one to cut assembly and waste.

Corrosion Resistant

Good resistance to rust and wear. Reliable in tough or outdoor environments.

We print several aluminum alloys. AlSi10Mg is our recommendation for most parts.

AlSi10Mg — Recommended

Our workhorse alloy. Strong, stable to print, and cost-effective for brackets, housings, and prototypes.

AlSi7Mg

More ductile and fatigue-resistant. A good pick for parts under repeated or dynamic load.

6061

A common structural aluminum. Needs special powder for SLM and suits simpler shapes best.

Design Review (DFM)

Our engineers check wall thickness, supports, and tolerances. We suggest changes that save cost and improve quality.

SLM Printing

We build your part layer by layer with AlSi10Mg powder and a fiber laser in a controlled chamber.

Post-Processing

We remove supports, then bead blast or anodize the surface for a clean, durable finish.

Inspect & Ship

We measure and inspect each part, then pack and ship worldwide with full tracking.

Aerospace

Lightweight brackets, heat exchangers, and ducting where every gram counts.

Automotive

Mounting brackets, housings, and cooling parts for lighter, faster vehicles.

Electronics

Heat sinks, enclosures, and structural frames that manage heat and weight.

Medical

Surgical tools, custom fixtures, and device parts built to tight specs.

New to metal 3D printing? These simple rules help your part print well and cost less.

Mind Wall Thickness

Keep walls at least 0.5–0.8 mm. Thicker walls print cleaner and stay strong.

Watch Overhangs

Slopes over 45° need supports. Steeper angles print with less support and less cost.

Add Escape Holes

Hollow parts need small holes so loose powder can be removed after printing.

Bead Blasting

A smooth, matte, even surface. Our standard finish after support removal.

Anodizing

A hard, colored coating that adds corrosion resistance and a clean look.

CNC Machining

Used on key features when you need tight tolerances beyond print accuracy.

Polishing

A brighter, smoother surface on selected areas for a premium finish.

We are a dedicated metal 3D printing factory. Every file is reviewed by engineers before printing. Every part is inspected before shipping. Your designs stay private with us.

What is aluminum 3D printing?

It builds solid metal parts from aluminum powder using a laser. The most common method is SLM (Selective Laser Melting), where a laser melts each layer until the part is complete.

What does SLM mean?

SLM stands for Selective Laser Melting. It is a type of metal 3D printing where a fiber laser fuses thin layers of metal powder into a dense, solid part.

What is AlSi10Mg?

AlSi10Mg is a lightweight aluminum alloy made for 3D printing. It is strong, prints with stable results, and resists heat and corrosion.

How strong is 3D printed aluminum?

AlSi10Mg reaches about 440 MPa tensile strength. That is strong enough for real, working parts, not just models.

How fast can you give me a quote?

Send us your files. Most quotes return within a few hours on workdays. We never take more than 24 hours.

What is your minimum order quantity?

There is no strict minimum. We make a single prototype or a full production run.

Will you keep my files confidential?

Yes. We treat all files and ideas as confidential. We sign NDAs when you need them.

Can you help with design (DFM)?

Yes. Our engineers review your design and suggest changes that cut cost, improve quality, or speed up delivery.

Which surface finishes are available?

Bead blasting and anodizing are standard. CNC machining and polishing are available for key features.

Can you print other aluminum alloys?

Yes. We also print AlSi7Mg and 6061 (with special powder). AlSi10Mg is our recommendation for most parts.

Do you provide samples?

Yes. We can make samples for your approval. The sample cost is credited back on a production order.
