Abstract

There are machines (3D printers) with which micrometer-sized components made of various materials can be joined together using various methods. However, if these parts, which are made up of massive components mostly in the millimeter range, are broken up and built from regular structures made of rods and surfaces to form the corresponding support structures in the micrometer range and if the structures are left open, a weight reduction and material savings is achieved. The stability can be improved upon and aligned, i.e. strengthened or weakened directionally or in the case of thermally stressed parts as in internal combustion engines, such that the surface is significantly enlarged and more cooling can be achieved. With today's commercial 3D printers, housing parts made of microstructural material can be produced for mobile devices such as vacuum cleaners, mobile phones, computers, glasses, and luggage case shells. If the dimensions of the current printer available for sale are enlarged while maintaining the precision, car chassis and aircraft components can be produced of microstructural materials.

Beschreibungdescription

Wenn man bei Bauteilen Gewicht reduzieren will, besteht die 5 Möglichkeit des Schäumens. Allerdings hat dies den Nachteil, dass der innere Aufbau regellos und geschlossen ist. Seit einigen Jahren sind Maschinen auf dem Markt, 3D Drucker genannt, mit denen man mikrometergroße Bauteile aus verschiedenen Materialien, zum Beispiel Kunststoff oder Metall durch 0 verschiedene Verfahren wie Kleben, Schweißen oder Lasersintern, zusammenfügen kann. Bis heute wurden diese Maschinen überwiegend für die Produktion von Modellen, Prototypen, Gussformen und medizinischen Kleinserien eingesetzt und nicht für die Produktion von Großserienteilen. Wenn man diese Teile, bestehend aus massiven Bauteilen meist im Millimeterbereich, aber auflöst und durch regelmäßige Strukturen aus Stäben und Flächen zu den entsprechenden Tragwerken im Mikrometerbereich zusammensetzt (siehe Fig 1 Axonometrie Mikrostrukturmaterial etwa 6x6x1 mm als Flächentragwerk einseitig offen und Fig 2 Axonometrie Mikrostrukturmaterial etwa 6x6x0,8 mm als Kombination aus Stab und Flächentragwerk dreiseitig offen) und diese offen lässt, erhält man je nach Ausformung große Gewichtsreduktion und Materialeinsparung.If you want to reduce weight in components, there is the possibility of foaming. However, this has the disadvantage that the internal structure is random and closed. For some years, machines have been on the market, called 3D printers, which can be used to assemble micrometer-sized components made of various materials, for example plastic or metal, by means of various methods such as gluing, welding or laser sintering. To date, these machines have been used predominantly for the production of models, prototypes, molds and medical small series and not for the production of high volume parts. If these parts, consisting of massive components usually in the millimeter range, but dissolves and composed by regular structures of rods and surfaces to the corresponding structures in the micrometer range (see Fig 1 Axonometry microstructure material approximately 6x6x1 mm as surface structure unilaterally open and Fig. 2 axonometry microstructure material about 6x6x0.8 mm as a combination of rod and tensile structure open on three sides) and leaves this open, you get depending on the shape of great weight reduction and material savings.

Außerdem gibt es je nach Material auch noch andere Verbesserungen. Man kann die Stabilität verbessern oder bei thermisch beanspruchten Teilen wie Verbrennungsmotoren dadurch, daß mit der Ausbildung als Stabtragwerk oder Flächentragwerk oder einer Kombination aus beidem die Oberfläche wesentlich vergrößert wird, auch eine bessere Kühlung erreichen. Wenn man die Abmessungen der bestehenden und käuflichen Drucker unter Beibehaltung der Genauigkeit vergrößert, dann wird es auch möglich sein, Autokarosserien und Flugzeugrümpfe oder Flugzeugflügel, bestehend aus Mikrostrukturmaterial zu produzieren. Wenn man davon ausgeht, dass eine Gewichtreduktion von 50% beim Bau eines Autos möglich ist, dann kann man sich ausrechnen, welche Einsparungen beim Transport und dem Energieverbrauch dazu möglich sind.There are also other improvements depending on the material. One can improve the stability or in thermally stressed parts such as internal combustion engines in that the surface is substantially increased with the training as a bar structure or tensile structure or a tensile structure or a combination of both, also achieve better cooling. By increasing the dimensions of existing and purchasable printers while maintaining accuracy, it will also be possible to produce automobile bodies and fuselages or aircraft wings made of microstructured material. Assuming that a 50% weight reduction is possible in the construction of a car, then one can calculate what savings in transport and energy consumption are possible.

Gewerbsmäßige Anwendung Eine gewerbsmäßige Anwendung ist möglich in der Produktion von Gehäuseteilen für mobile Geräte, zum Beispiel: Staubsauger, Mobiltelefone, Computer, Brillen und Kofferschalen. Eine gewerbsmäßige Anwendung wird möglich werden in der Produktion von Autoteilen wie Karosserien, Reifen, Motorgehäusen sowie Flugzeugen und Raketenteilen. Commercial use Commercial use is possible in the production of housing parts for mobile devices, for example: vacuum cleaners, mobile phones, computers, spectacles and case shells. Commercial application will become possible in the production of auto parts such as bodywork, tires, engine casings, aircraft and missile parts.
