Method for producing three-dimensional objects by means of electromagnetic radiation and applying an absorber by inkjet method

Die vorliegende Erfindung betrifft ein Verfahren zum Verbinden von Material zur Herstellung von dreidimensionalen Objekten mittels selektiver Erwärmung durch elektromagnetische Energie, welche entweder nicht kohärent und/oder nicht monochromatisch und/oder nicht gerichtet ist, mit einer Wellenlänge zwischen 100 nm und 1mm. Dabei kann die Strahlung punkt- oder linienförmig abgegeben werden oder aber flächig. Es können auch mehrere Strahlungsquellen kominiert werden, um die Schnelligkeit des Verfahrens zu erhöhen. Die Selektivität des Aufschmelzens wird durch das Aufbringen eines Absorbers auf bestimmte Teilbereiche einer Schicht aus einem pulverförmigen Substrat und anschließendes Erwärmen des Absorbers mittels elektromagnetischer Energie in einer Wellenlänge zwischen 100 nm und 1 mm erreicht. Der erwärmte Absorber gibt die in ihm vorhandene Energie an sein ihn umgebendes pulverförmiges Substrat ab, welches dadurch aufgeschmolzen wird und nach dem Abkühlen fest miteinander verbunden ist. DOLLAR A Das Verfahren ist deutlich flexibler, preiswerter und schneller als herkömmliches Lasersintern. The present invention relates to a method for joining material for the production of three-dimensional objects by means of selective heating by electromagnetic energy, which is either non-coherent and / or non-monochromatic and / or non-directional, with a wavelength between 100 nm and 1 mm. In this case, the radiation can be emitted point or line or even surface. It is also possible to combine several radiation sources in order to increase the speed of the method. The selectivity of the melting is achieved by applying an absorber to certain portions of a layer of a powdery substrate and then heating the absorber by means of electromagnetic energy in a wavelength between 100 nm and 1 mm. The heated absorber releases the energy present in it to its surrounding powdery substrate, which is thereby melted and is firmly connected to each other after cooling. DOLLAR A The process is ...

DOLLAR A Bei dem RP- bzw. RM-Verfahren entsteht ein blockartiger Körper, der zum einen aus den gewünschten Bauteilen besteht, zum anderen und meist überwiegenden Teil aus nicht aufgeschmolzenem Pulver, welches bis zum Entformen bzw. Auspacken mit den Bauteilen in diesem Block verbleibt. Das nicht aufgeschmolzene Pulver kann nach Sieben und Zugabe von Neupulver in einem weiteren Bauprozess eingesetzt werden (Recycling). DOLLAR A Nicht aufgeschmolzenes Pulver gemäß dem Stand der Technik neigt unter den im Bauraum einer geeigneten RP/RM-Apparatur gegebenen Bedingungen (Temperatur, ggf. Restsauerstoffgehalt) zur Nachkondensation - in einzelnen Fällen auch zu unkontrollierter Abspaltung von Aminoendgruppen - und das zurückgewonnene Pulver zeigt eine deutlich erhöhte Lösungsviskosität und lässt sich nicht oder nur noch eingeschränkt im nächsten Bauprozess einsetzen. DOLLAR A Durch die erfindungsgemäße Mischung von entgegengesetzt difunktional geregeltem Polyamid- oder Copolyamid lässt sich ein Polyamid- oder Copolyamid-Pulver mit nahezu konstanter Lösungsviskosität herstellen, welches sich ohne Zugabe von Neupulver mehrfach im RP/RM-Verfahren einsetzen lässt.

An electronic control unit to control a set of fuel injectors

The invention relates to a device and a method to control fuel injection in a vehicle. The ECU (100) receives a set of engine parameters (103) and a pressure signal (104) to control a set of fuel injectors (104 to 107). The ECU (100) computes the amount of fuel required for each cylinder for one combustion. The amount of fuel required is computed based on the engine parameters (103). The ECU (100) also computes the maximum available time for the injection, the number of fuel injectors needed to be opened to inject the required amount of fuel and the durations of their openings. The ECU (100) opens the required number of fuel injectors (104 to 107) accordingly. The fuel injectors (104 to 107) inject the required amount of fuel in the intake manifold (110) of the engine where the fuel gets mixed with the air. The air-fuel mixture is delivered to the cylinders as explained previously. The ECU (100) operates the fuel injectors (104 to 107) in such a way that at least one of the fuel injectors is opened for a much longer duration than at least one other fuel injector. This will bring down the number of openings and closings of a fuel injector and increases the life of the fuel injectors (104 to 107).
