中文Industrial Metal 3D Printing with SLM/ DMLS Strong, Precise, Production-Ready
High-performance metal parts for aerospace, automotive, medical, and beyond.
What is Metal 3D Printing
SLM (Selective Laser Melting) or DMLS is an additive manufacturing process that uses a high-power laser to fully melt and fuse metal powders into dense, functional parts with excellent mechanical properties.
- Fully dense metal parts — comparable to forged materials
- Complex geometries — lightweight lattice & internal channels
- Wide material range — aluminum, stainless steel, titanium, Inconel, and more
- Suitable for end-use production — aerospace, medical, robotics, industrial and automotive

Excellent 4.9 out of 5 
I regularly use the 3D printing service that IN3DTEC offers and I'm very happy with the end products I receive as well as the quality of service. Parts arrive with very good dimensional accuracy and excellent finish. I also receive great advice about making my prints better. I definitely recommend IN3DTEC!
Dominik Dominiak
My experience working with the team at IN3DTEC was wonderful. The team was easy to work with and provided me with useful feed back about my design. Also the price was just right.
Evan Kuester
Exceptional service, always willing to work with the customer to ensure parts are built to spec. Quick, reliable turn around, high quality and reasonably priced CNC/3D Printed parts.
Ron Miranda
Working with in3dtec was great. The communication was really good - they responded always fast and to my satisfaction. Their statement about competitive prices is totally true and the quality is nothing to complain about. Hope in3dtec will continue with their great work. I will definitely order again.
Daniel Kuehnle
First time using and I must say the quality for the part is excellent. The ordering and quoting was very good on the web site. The shipping and turn around time is 1st Class. I would recommend to anyone wanting a top quality part (or parts) and outstand shipping.

How Metal 3D Printing Works
The 3D Printer begins sintering each layer-first the support structures to the base plate, then the part itself, with a laser aimed onto a bed of metallic powder. After a cross-section layer or powder is micro-welded, the build plate shifts down and a recoater blade moves across the platform to deposit next layer of powder into an insert build chamber. The process is repeated layer by layer until the part is complete.
Applications of Metal 3D Printing
Aerospace – Lightweight, complex aircraft and turbine parts.
Automotive – Custom car parts and rapid prototypes.
Bicycles & Motorcycles – High-performance frames and components.
Medical & Dental – Patient-specific implants and surgical tools.
Robotics & Automation – Durable parts for robots and drones.
Industrial Machinery – Spare parts and functional tooling.
Consumer Products & Electronics – Housings and custom components.
Energy & Oil/Gas – Turbines, pumps, and high-pressure parts.
