His lecture:

This presentation will show the possibilities to make real products for the choclate production. With the help of medical grade 3D-printing resins one can produce very detailed customised chocolate molds in a very short time. So it is possible to turn around (from order to delivery) some small batches of individualised chocolate-bars in less than a day - big possibilities for small local Chocolatiers to meet the exclusive needs of their customers an gather a part of a totally virgin market. The presentation will show step by step how to produce this kindof molds.

Application example: Customer-specific lubricated and maintenance-free wear parts produced by 3D printers - Tom Krause, igus GmbH

2014 - now  igus: Product manager iglidur Tribofilament (3d-printable bearing-materials)
2009 - 2014  igus: Research engineer bearings

2011 - 2013 Studies of business administration (MBA) - part-time
2004 - 2008 Studies of Mechanical Engineering (Dipl. Ing. FH)

His lecture:

igus developed bearing-materials which are process-able with different 3d-printing methods (FDM, SLS). Wearparts that are produced by 3D-printing with these materials have similar wear-characteristics than with conventional methods manufactured bearings.

That is why 3d-printed wear-parts are already used in all kinds of machinery manufacture industries; at series from up to 1000 pieces and also single pieces for special purpose machinery manufacture.

Katjes Magic Candy Factory is not only the first food 3D printer to reach consumer retail, it is also the fastest in the development segment as each print takes less than 5 minutes. 

Candy lovers can choose from 8 delicious vegan flavors which are made from real fruit and vegetable extracts. All the magical varieties are made without gelatin and are free from gluten, nuts, milk, and the entire range at Magic Candy Factory is also Halal and Kosher friendly, making it suitable and safe for anyone to enjoy. 


Development of tailor-made materials for additive production - Dr. Andreas Pelz, m4p material solutions GmbH

Dr. A. Pelz started its AM-related powder business 2 years ago in order to bring its knowledge and experience about metal powders into the AM-industry. Before this, he worked for 10 years as Leader of an R&D Department within a powdermetallurgical orientated company. During this period he worked on and finished its PhD thesis which investigated the metal powder atomisation process in detail.

His lecture:

Th i s presentation focuses on metal powder materials. As introduction a general overview on metal powders and its production methods is given. From the manigfold possibilities of metal powder production the most promising ones will be bespoken in more detail and put into relation to the requests on their applied materials from users of AM-technology. An example on an general approach when dealing with new materials for lasermelting processes will be given at the end of the presentation.

His lecture:

Over the last 30 years, since the first 3D-Object was produced layer-by-layer, additive manufacturing made its way into industry as well established prototyping technology. In the meantime, additive manufacturing stands for a large and growing group of different process technologies for a large variety of materials at different scales. Today additive manufacturing is taking the next step towards a manufacturing technology for series and end customer products and applications. Additive Manufacturing / 3D printing starts to change manufacturing fundamentally and provides innovative new solution to various challenges. Companies are now faced with the questions how implement additive manufacturing in their value chain. Based on several examples the talk shows good practices how companies develop the first successful additive manufacturing series or end customer part. The talk addresses the challenges and gives insights how companies can identify additive manufacturing application and develop innovative solutions.
