Laser deposition welding & milling in a single solution

The AMB Stuttgart started yesterday with the halls full of visitors. At the DMG MORI booth (quite crowded too), many novelties. Among them, the new Lasertec 65D hybrid machine. Let’s have a look at it.

The new Lasertec 65 3D - ALL IN 1: Laser Deposition Welding & Milling -additive Manufacturing in Milling quality.
The new Lasertec 65 3D – All in 1: laser deposition welding & milling -additive manufacturing in milling quality.

For the first time additive manufacturing is integrated into a high-tech 5-axis milling machine. This innovative hybrid-solution combines the flexibility of the laser metal deposition process with the precision of the cutting process and therewith allows additive manufacturing in milling quality.

10 times faster
The process uses the metal deposition by powder nozzle, which is up to 10-times faster than the generation in the powder bed. Up to now additive technologies have been used to generate prototypes and small parts. By combining both, additive manufacturing via powder nozzle and the traditional cutting method in one machine, totally new applications and geometries are possible. Especially large workpieces with high stock removal volumes are now possible to be machined in an economical way.

Opening new possibilities to designers
The flexible change between laser and milling operation allows the direct milling machining of sections which are not reachable anymore once the part finished.

Highlights Lasertec 65 3D

  • Complete machining in milling quality with fully automated change between milling and laser operation
  • Laser deposition welding with powder nozzle: 10-times faster vs. powder-bed-process
  • Wall thickness from 0,1 mm to 5 mm possible (depending on laser and nozzle geometry)
  • Feasibility of 3D-contours without backing geometry: e.g. machining of a flange, machining of a cone


To be seen in Stuttgart on the Entrance West, Hall 7, Booth A01

3D Printing on the micrometer scale

Nanoscribe presents a novel high-speed 3D printer, the Photonic Professional GT. It is the world’s fastest commercially available 3D printer for micro and nanostructures. Nanoscribe’s next-generation 3D printer enables very fast and highest-resolution manufacturing of three dimensional micro-objects, which are often smaller than the diameter of a human hair.

From left to right: human hair, Nanoscribe  Empire State Building printed with a Photonic Professional GT system by means of the DiLLMethod and Miniature-spacecraft printed with a Photonic Professional GT system in less than one minute.
From left to right: human hair, Nanoscribe Empire State Building printed with a Photonic Professional GT system by means of the DiLLMethod and Miniature-spacecraft printed with a Photonic Professional GT system in less than one minute.

The printing speed was increased hundredfold by employing a new laser lithography method, enabling completely new applications.

Speed: minutes turn into seconds
The significant increase of the printing speed was achieved by implementing a galvo mirror system similar to those used in laser show devices or scanning units of CD and DVD drives. Reflecting a laser beam off the rotating galvo mirrors facilitates rapid and precise lateral laser focus positioning.

Space shuttle in minutes
Just for comparison: Using the novel system, the time required for printing a miniature spacecraft was reduced from hours to minutes without any loss in structure quality! The company’s customers will profit tremendously from the extended application range of those product. The GT version of the Photonic Professional will be equipped with a new modular controller, which facilitates the introduction of optional hardware extensions in the future. Various new features have also been integrated into the software. The electronics cabinet has been redesigned for a more elegant and modern appearance.

Mechanism: Two-photon Polymerization
The direct laser writing technique underlying the 3D printing method is based on two-photon polymerization. Just as paper ignites when exposed to sunlight focused through a magnifying glass, ultra-short laser pulses polymerize photosensitive materials in the laser focus. This crosslinking of polymer chains renders the exposed volume insoluble relative to its unexposed environment. After washing away the unexposed material in a developer bath, the exposed regions remain as self-supporting 3D micro- and nanostructures.

SLS is one of the new additive manufacturing solutions prsented in Erfurt during RapidTech.


With a user conference, design engineer day, specialist forums for the aviation and medical and dental technology industries, and the specialist trade fair itself there will be ample opportunity for interchange among newcomers to the field, experts, researchers and users, covering both theory and practice. In tandem with Rapid.Tech, the second German Personal Fabrication Convention FabCon 3.D will be taking place in Erfurt from 15–17 May 2014.

Key technology for nowadays challenges
Sustainability, the Industry 4.0 project and individualisation are all global trends, and there is one key technology required to implement them all: additive manufacturing (AM). To exploit the potential of AM effectively it is necessary to be fully informed about all the latest developments covering materials, processes and machines. “Generative manufacturing processes are becoming ever more relevant across multiple industries and are playing an increasingly important part in production processes. This is generating an enormous demand for information, as well as for an interchange of experiences and discussion”, reported Wieland Kniffka, Head of Messe Erfurt [Erfurt trade fair]. “Rapid.Tech sets the standard here, with its mix of think-tank, knowledge transfer and an exhibition geared toward practical applications.”

To exchange knowledge
Specialist forums under the headings of “Aviation”, “Medical Technology” and “CAD/CAM and Rapid Prototyping in Dental Technology” plus the user conference entitled “New Technologies” and the design engineer day will all give industry-insiders a chance to look at the latest applications, discuss the possibilities of additive processes in their specialist fields and cast an eye towards the future. This is also facilitated by the specialist trade fair, where around 100 exhibitors will be showcasing new developments and follow-up products.

Additive manufacturing: technology, trends and knowledge

Additive manufacturing offers an enormous potential for faster, more economical and sustainable production. In order to exploit these capabilities comprehensive information on new developments of materials, techniques and machinery is indispensable.

The 10th Rapid.Tech, which takes place from May 14 to 15, 2013, is the perfect place for gathering all the information and for exchanging knowledge. This is ensured, on the one hand, by the clear focus on finished products. On the other hand, the close correlation between application-oriented lectures and exhibition program provides added value. Rapid.Tech 2013 in Erfurt (Germany) will also be the stage for the 7th Student Design & Engineering Award for Rapid Manufacturing.

A new way to manufacture
Shorter product life cycles, increasing cost pressure, rising environmental demands and dwindling resources require rethinking the way of manufacturing in many industries. An answer to this can be additive manufacturing (AM) – not only in prototyping but also in in small and large scale manufacturing. Thus it is no surprise that industry analyst Wohlers Associates has confirmed a growth of almost 30% in 2011 for the additive manufacturing industry and has forecasted an annual growth rate in the double digit range for the upcoming years.

The answers we all need
However, which possibilities does additive manufacturing offer for faster, more economical and sustainable production and how can they be used in an optimised way? Answers to these questions will be provided at the 10th Rapid.Tech taking place on 14th and 15th of May 2013 in Erfurt (Germany), which has become one of the leading events for application-oriented additive manufacturing over the past ten years.
