  2. 16. Experimental study and simulation of sintering of 316L components produced by binder jetting

    Author : Alberto Cabo Rios; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binder jetting; 316L stainless steel; additive manufacturing; dilatometry; sintering modelling; Sintering; anisotropy;

    Abstract : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

  4. 17. Fabrication Technology for Efficient High Power Silicon Carbide Bipolar Junction Transistors

    Author : Reza Ghandi; Martin Domeij; Anant Agarwal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Other engineering physics; Övrig teknisk fysik;

    Abstract : The superior characteristics of Silicon Carbide as a wide band gap semiconductor have motivated many industrial and non-industrial research groups to consider SiC for the next generations of high power semiconductor devices. The SiC Bipolar Junction Transistor (BJT) is one candidate for high power applications due to its low on-state power loss and fast switching capability. READ MORE

  5. 18. Sintering simulation framework for 316L stainless steel components manufactured by binder jetting

    Author : Alberto Cabo Rios; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering modelling; additive manufacturing; binder jetting; stainless steel.; dilatometry;

    Abstract : Binder Jetting (BJT) is an additive manufacturing (AM) technology allowing mass-production of small to medium-size metal components. BJT is a multi-step AM technology, where the geometrical shape of components is provided during the printing step, and the final properties are achieved through a second consolidation step - sintering.
