Ever since this introduction Formatec worked on the next step. Breaking down the limitation of just one color for an aesthetical ceramic component. In 2013 this becomes reality by introducing 2K injection moulding for zirconia. The outcome is a result of combined powder development, injection moulding and sintering research.

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.

For those who would like to read an example of success story in the additive manufacturing, you can read the recent Eurotec storie about Ecoparts here.

Springmann just announced it will present many highlights from its broad range of solutions in terms of production means and peripherals on its A09 booth (Halle 1) at Prodex. Among other, visitors will be able to discover the Index MS 22C-8 as Swiss premiere.

With the new INDEX MS16C of the MultiLine series, the Esslingen multi-spindle specialists just presented a CNC multi-spindle lathe featuring six spindles for up to 16 mm diameter parts. This new machine won’t be shown at Prodex but interested people will be able to be informed comprehensively on the booth. You can read the Eurotec news about it here. (And there will be a complete article in Eurotec’s next issue).

A few highlights to discover on the booth

  • Sharpening cell: grinding with Anca, preparation of cutting edges with Otec, measurement of cutting edges with Zoller.
  • Index-Traub will present the productivity multiplier: the new eight spindles MS22 C-8 as Swiss premiere (picture) as well as two highly productive sliding head/fixed head Traub lathes.
  • A R18 veteran will also be exhibited as witness of the past; an obvious example of the force of innovation, reliability and longevity of Index.
  • Demonstrations of the powerful Heller H2000 machining center (you can read the news published on Eurotec’s here).
  • Hembrug machine for turning/dressing with which very high precision components related to the SwissFEL project at the Paul Scherrer Institute will be produced at Oerlikon Mechatronics AG, Trübbach.
  • Multiclean-LC-III, washing installation, synthesis of the long experience gained by Höckh.
  • Co-exhibitor, Ecoparts will show examples of typical subcontracting parts carried out cost-effectively with an EOS machine working by selective laser sintering (you can read the Eurotec article about EOS and Ecoparts here).

Many other machines and solutions for machining metal and synthetic materials will be waiting for you on the Springmann stand, located on the ground floor of Hall 1.

Springmann focuses on watch industry…

..and high precision operations. At this year’s EPHJ on booth E42 visitors will be able to discover three different technologies dedicated to highly demanding fields like watch industry and others.

There are always new ways to realize parts or operations and this year’s highlight at Spingmann’s booth will be

  • SLS (selective laser sintering) with precious material
  • Industrial polishing for small parts
  • Two side grinding


SLS – still little known technology
The principle of building the parts is simple, a thin layer of metal powder is deposited on the working surface (250 mm x 250 mm), and a laser moves in X and in Y to merge metal on selected locations. Once the “cut” at this level of the part is fully sintered, a new layer of material is deposited and the laser moves to selectively sinter metal at required locations. The part is thus constructed layer by layer. Huge advantage, shapes are not limited by conventional technologies of machining by material removal.
A new world of possible parts opens…

1- digital model of the part, 2-deposition of the first layer of powder, 3-fusion of the powder in the cross-section of the part, 4 – platform goes down, 5-deposition of a new layer of powder, 6 – the operation is repeated until the part is completed (fusion, filing, lowering), 7-elimination of the non-melted material, 8-the part is complete.

To be discovered on Springmann’s booth at EPHJ from June 5 to 8 in Geneva. Customers of the company and interested people can ask for entrance tickets at [email protected] or by phone on +41 32 729 11 29.



What about doing “impossible” parts?

Thanks to the technology of SLS additive manufacturing (Selective Laser Sintering), Ecoparts located in Rüti near Zürich (Switzerland) can achieve functional prototypes in metal and small series of complex parts with very short delivery time.

“Ecoparts is the only company of its kind in Switzerland,” says Mr. Kündig its director. Working with two EOSint M 270 machines produced by EOS (recently represented in Switzerland by Springmann) this small structure is specialized in the manufacturing of complex metal parts by laser sintering.

Still little known technology
The principle of building the parts is simple, a thin layer of metal powder is deposited on the working surface (250 mm x 250 mm), and a laser moves in X and in Y to merge metal on selected locations. Once the “cut” at this level of the part is fully sintered, a new layer of material is deposited and the laser moves to selectively sinter metal at required locations. The part is thus constructed layer by layer. Huge advantage, shapes are not limited by conventional technologies of machining by material removal. Mr. Kündig says: “For example we produce parts that include curved Interior cooling channels. To achieve such parts without additive manufacturing, we should resort to casting which is incompatible with the notions of prototypes and small series, both in terms of costs and deadlines”.

Very short deadlines
“According to our workload, an urgent complex part may be provided within a few days” says Mr. Kündig which adds that the normal delivery times are around two weeks. This reactivity is one of the reasons why many leading-edge companies use Ecoparts’ services (especially in the medical). They often pass through long design and validation processes and when it is time to produce the parts, the production deadline is an important element of differentiation.

The benefits of the process at Ecoparts’

  • All possibilities of design
  • Very short manufacturing time
  • Flexibility and reactivity
  • Very high quality parts
  • Reduced costs
