In Pictures: 3D printing - How does it really work?

Here are the nine most common 3D printer technologies

Technology No. 7: SLM What it is: Selective laser melting

Inventors: Dr. Dieter Schwarze and Dr. Matthias Fockele of F&S Stereolithographietechnik GmbH; and ILT researchers Dr. Wilhelm Meiners and Dr. Konrad Wissenbach

Year: 1995

Materials: Stainless steel, tool steel, cobalt chrome, titanium, aluminum in atomized form

Process: A high-powered fiber laser beam fuses fine metallic powders together to create three-dimensional metal parts. Although known as laser sintering, this SLM process actually fully melts the metal into a solid homogeneous mass, which is more similar to Electron Beam Melting (EBM), which uses an electron beam as the energy source. Trade names include DMLS and LaserCusing.

Price Range: up to $500,000

Systems Sold by: ReaLizer, Renishaw

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
