What is DMLS Printing?

What is DMLS Printing?

DMLS is an industrial-grade metal additive manufacturing process that uses a high-power laser (200-400W) to melt metal powder layer by layer (with a layer thickness of 20-60μm), directly forming complex metal parts.

We are equipped with industrial-grade high-precision large-scale 3D printing equipment, which enables us to quickly meet the production demands for various complex parts. Regardless of the size or application field of your project, we can offer competitive prices and high-quality products. We can provide a quotation within 24 hours and deliver the goods within the shortest 3 days, helping you accelerate the product development process.

The DMLS Process Overview

The DMLS Process Overview

Qiying adopts a full-process digital control system to ensure that every step from the document to the final product complies with the ISO 9001 quality standards, providing customers with high-precision and highly consistent SLA printing services. A Comprehensive Analysis of the Entire Process of SLA Light-Curing 3D Printing:

Substrate pretreatment
Substrate pretreatment

Select a metal substrate (titanium/aluminum/steel) that matches the material
Preheat the substrate to 150-200℃ to reduce thermal stress

Powder spreading
Powder spreading

The scraper evenly lays a 20-60 μm layer of metal powder
Inert gas environment (argon) with oxygen content < 0.1%

Laser melting
Laser melting

200-400W fiber laser selective scanning Local instantaneous temperature reaches 1600-3000℃
The molten pool size is precisely controlled to 50-100μm
