Workshop - Philosophie & Technik

Weiter denken ....

Unser Workshop richtet sich an Ingenieure, Techniker, Architekten, Designer und andere technische Berufe. Innovationen werden möglich, wenn man etablierte Bahnen und starre Konzepte verlässt. Das Neue kann nicht geplant werden. Die WERKSTATT FÜR ZWECKFREIEN NUTZEN des Künstlers Michael Evers bietet einen Raum für kreative Improvisation. Hier können Technologie und Rationalität mit den Augen der Philosophie gesehen werden, künstlerische Experimente mit Farbe und Zeichenstift eröffnen innere Freiheiten für den Perspektivenwechsel. So wird analytisches Denken und effizienzorientiertes Handeln außer Kraft gesetzt. Im künstlerischen, zweckfreien Spielen kommen bisher unbekannte Potenziale und Eingebungen in die Sichtbarkeit. 

 

Wenn wir verstehen, warum wir uns in unserem strukturierten Handeln zum Teil selbst blockieren, öffnen sich Freiflächen für neue Ideen. In unserem Workshop werden Anregungen gegeben, aus der Routine auszusteigen und Grenzen zu durchbrechen. Michael Evers referiert über verschiedene Themen aus Philosophie und Kunstgeschichte und führt Sie durch den kreativen Workshop. Sie lernen nicht nur neue Denkweisen kennen - gewünscht ist auch das Gespräch, der Austausch untereinander und die Entstehung neuer Netzwerke.

Concrete Textile

New INTERPRETATION OF TEXTILE CONCRETE

g.tecz sponsored university project

Mrs. Kühner, student from the Weißensee Kunsthochschule Berlin developed a new textile concrete with G.tecz's high strength concrete. Mrs. Kühne sucessfully transfered the technology into a fantastic new product. We are happy to support the project with material and know-how.

success story

Textilbeton ist mittlerweile als robuster Verbundwerkstoff bekannt. Aber was genau soll nun »Betontextil« sein? Das Projekt ist eine Materialstudie, die im Rahmen einer Masterarbeit im Fachgebiet Textil- und Flächen-Design der Weißensee Kunsthochschule Berlin entstand. Das Ergebnis ist erstaunlich einfach: Textilbeton sieht aus wie Beton, Betontextil erscheint in textiler Struktur.

Heat Resistant Special Concrete Molds for Aluminum Casting, developed by G.tecz.

Concrete Molds for Liquid Metals

Nano optimized concrete matrix systems are enabling new solutions, not only in the building industry. G.tecz Engineering’s latest development is a high temperature resistant optimized concrete matrix, based on Portland cement in combination with other cements and high temperature resistant fines.

The material can take temperature shock loads of 900°C up to 1400°C in a short time range while keeping mechanical performance for an outstanding time span. Next to the outstanding mechanical performance and thermal resistance, the material is extremely affordable compared to industrial standard molds made of steel. Fields of applications are molds for liquid metal casting as well as chassis for high temperature ovens or heat shields of machines.

Application – The new developed concrete was tested in laboratory as well as industrial scale for aluminum casting. Industrial partners from the automotive industry proofed the concept and economical aspects of the technology. Main idea of the concrete mold is to replace steel molds for prototype developments as well as usage for zero and small series productions.

Advantages of the system are;

  • Easy to realize concrete molds due to the fluid concrete behavior due to its self leveling and doesn’t require temperature treatment for the hardening process.
  • Simple and precise form generations (olds of the molds) by 3d printing the negatives.
  • 3 times less weight compared to steel molds
  • 90 percent cost savings compared to steel molds
  • Surface near cooling or heating channels are possible and can be directly integrated in the concrete mold.
  • Usage of the mold for several cycles
  • Release agents are not necessarily required for the aluminum casting.
  • High compressive strength of the concrete is possible, up to 300Mpa.

G.tecz’s industrial partners tested the mold system with 900°C hot and fluid aluminum that was casted in the pre-heated concrete mold as well as aluminum injection molding with 800bar pressure. Both tests were successfully mastered by the concrete mold. Molds and aluminum parts were made as test elements for engines for cars. The precision of the casted aluminum elements hat been very high and tolerances were accepted.

The concrete mold technology is also interesting for small companies (SME) that are related to the liquid metal molding industry and are producing smaller aluminum elements like door or window handles, spare parts for cars, machine parts and so on. G.tecz developed a complete and simple solution: Clients can develop their products via computer aided design (CAD) and print their mold negatives with a simple 3D Printer. The printed negative is used for concrete casting – that’s it. The whole process can be done within hours, very cost effective and independent from suppliers.


Material properties can be adapted regarding project requirements. The following parameters are representative:

– Compressive strength: 190Mpa – 350 MPa

– Tensile strength (matrix): 9 – 20 MPa

– Flexural strength (matrix): 20 – 27 MPa

– Flexural strength (reinforced): 35 – 75 MPa

– Fracture energy: up to 90 kN/m

– Carbonating up to 1.0 mm after 3 years

– Chloride Diffusion not measurable

– Water resistance not measurable

– Frost-resistance < 100 g/m2

– Dispersion up to 80 cm- shrinkage: 1 – 1.5 ‰

– crack width << 0.1 mm

– Temperature resistance up to 1750 °C

– Weight: 2.4 – 2.7 t/m3

– heating rate: 1750°C within 120 sec. possible

– Thermal conductivity adjustable: 0.2 – 0.065 W/mK

 

Further applications of the heat resistant concrete are chassis of oven systems as replacement for ceramic tiles. New oven systems are heated with gas turbines and are performing a temperature difference from 20°C to 1400°C within 2 minutes only.

General oven systems with ceramic heat shields do show erosion problems after a few weeks, concrete shields don’t. Advantage of those oven systems, compared to electronic heated systems, they can be used in periods only and if required for a few hours; they don’t have to be heated over days.

Advantage of the special concrete heat shield is the high temperature resistance, the affordable price and the possibility to design the oven in a complete new design.

Secondary steel structures and constructions are not required. Because of the fluid concrete, any geometry can be realized – monolithic plug and play prefabricated oven blocs can be produced.

G.tecz is specialized in the development of cement bonded high tech materials for the industry. Tailor made economic and ecologic solutions from small series to big industrial applications. The company offers complete solutions from material development, mold and product innovations up to consultancy for setting up production lines and production facilities.

3D Druck Beton - Pilotprojekte

3DP - Additive Layer Manufacturing mit Beton - eine von G.tecz Engineering speziell entwickelte Zement gebundene Fertigmischung für Pulver verarbeitende Drucker macht dies möglich. Der nano optimierte und rein Zement gebundene Werkstoff benötigt lediglich Wasser zur Reaktion und erreicht Druckfestigkeiten von ca. 5 N/mm2 bei einem Gewicht von 2kg pro Liter. Durch seine offene Struktur eignet er sich nicht nur für den Druck von Aluminiumguss Formen sondern auch z.B. für den Druck von Designprodukten bis hin zu Repliken von Statuen oder Ornamenten zur Anwendung in der Altbausanierung. Der sandsteinartige Charakter des 3D Druck Betons kommt hierbei den architektonischen Ansprüchen entgegen.

Die Firmen Voxeljet und G.tecz Engineering sind die Entwicklungspartner des neuartigen 3D Druck Betons und suchen Interessenten für Pilotprojekte. Firmen können sich für den Pilot-Druck bewerben und an der Evaluierung des neuen Werkstoffs teilnehmen. Branchenübergreifend soll das Material sowohl für den Aluminiumguss, wie aber auch für Produkt- oder Designanwendungen im Innen- oder Außenbereich getestet werden. Engagierte, 3D Druck interessierte Firmen und die Entwicklungspartner werden in Kleinserien das Druckverfahren, das Material sowie die Druckergebnisse evaluieren. Vor Verkaufsstart können Interessenten die einmalige Chance nutzen und das Material für ihre Anwendungen einsetzen.

REAL ADDITIVE MANUFACTURING - 

23. October, 2015 - Delft University, Berlage Rooms

 

IN SEARCH FOR THE NO NONSENS APPLICATION OF 3D PRINTING IN THE BUILT ENVIRONMENT.

 

>> Additive Manufacturing (AM) is referred to as a very promissing technique. What are the important functions and characteristics of produced building components? Can additive manufactured elements already be implemented widely in the building industry, or should their performance be improved first? This Think Tank will focus on the implementation of AM in the building industry,

investigating questions regarding durability, (anisotropic) material behavior and which materials are suitable. Another ambition concerns the possibilities of combining various materials in one AM process. Are ‘new’ materials with matching production systems required? And there are more challenges to explore. During the discussion we invite you to be creative and think about the applications of AM. Let’s give the building industry a boost with Real Additive Manufacturing! <<

Press - 3D-Printer Concrete

(PresseBox) (Kassel) Three-dimensional print technologies are worldwide under permanent development and are not only revolutionizing the production but also the products it selves. New and almost endlessly possibilities occur and lead to rethinking in nearly every line of business.

Now three-dimensional printing is also possible with concrete. The concern G.tecz Engineering, which is specialized on cement bonded high-tech-materials, developed a nano concrete for three-dimensional industrial printer, which waives completely polymer binder that was necessary until now. The dry mixture of the material will be regularly batched in printer, which already exist and handle powder, so it reaches excellent material properties. With this additive print method, 150-micrometer separate coats will be constructed to complex component parts. The size of the concrete elements is only limited by the available space of the printer.

G.tecz's purely cement bonded three-dimensional print concrete is a nano optimized dry-mix, that reaches a compressive strength of 5 N/mm2 according to the pressure sewer system and is therefore harder than many conventional porous concrete, which are known from the building industry. G.tecz is permanent enhancing the concrete to raise the tightness and the strength continuously. The concrete is with approximately 2000 kg/m3 lighter than normal concrete but just as weatherproof and temperature-resistant as normal concrete. Also 1000 degrees aren't a challenge for the material.

The area of application of the material is multifaceted and ranges from product design and architecture to concrete formwork for aluminum casting respectively permanent mold casting. In cooperation with the industry partner Voxeljet AG there were printed casting prototypes for bicycle charging points and decorative elements from the division of architecture. Even printing of statues or decorative elements for refacing old buildings are possible.

Three-dimensional print concrete also offers great possibilities for the aluminum industry. Because of his extreme resistance to heat, can the material be used for printing of casings for aluminum casting respectively permanent mold casting. The material doesn't require any chemical binder, so almost perfect aluminum molds can be generated without any inclusion. The machine finishing of the aluminum can be reduced significant. Furthermore the casings can be used several times and reach substantial economic advantages compared to other methods.

The three-dimensional print concrete can be coordinated individual to printer and print methods. Furthermore also the strength of the material can be adjusted according to the customer's requirements. G.tecz Engineering offers worldwide customized solutions for three-dimensional print concrete and opens a new chapter for concrete for the industry.
