What technology to use?

What 3D-Printing technology is right for your application?

It is not a simple question as there are so many different categories of technology when it comes to 3D-Printing and sometimes it is difficult to decide which ones to use. 

Here we look at a rough overview of technologies. We focus on the most common industrial ones that are available on the market. Fused deposition modeling (FDM) would be considered as one of the most common ones but we leave it out from this as we don’t offer it and consider it a technology that companies can utilize themselves by purchasing some basic equipment. 

DMLS, SLA, and SLS Technologies

Each 3D printing technology has its own strengths, weaknesses, and requirements. The following table summarizes some key characteristics and considerations.

 

Direct metal laser sintering (DMLS)

VAT Photopolymerization (SLA, 3SP) Selective Laser Sintering (SLS)
Resolution ★★★★★ ★★★★★ ★★★★☆
Accuracy ★★★★★ ★★★★★ ★★★★☆
Surface Finish ★★★☆☆ ★★★★★ ★★★☆☆
Throughput ★★☆☆☆ ★★★☆☆ ★★★★★
Complex Geometry ★★★☆☆ ★★★★☆ ★★★★★
Durability ★★★★★ ★★☆☆☆ ★★★★☆
Economical ★★☆☆☆ ★★★☆☆ ★★★★★  
Ideal Applications low volume production, tooling, dental, DMLS have mechanical properties equivalent to a cast metal part. Low volume production, concept models, prototypes, master patterns, scale models, optical parts. Prototypes, serial production, end use parts, high heat & chemically resistant applications.

 

A lot of techniques exist and sometimes your application needs these but we can offer consultation to help you decide. Contact us for details if you wonder what is the best for you.
