    Sammanfattning : 3D-printing, också känt som additiv tillverkning, är en tillverkningsmetod som har revolutionerat många branscher och har växt stort både inom industrin och för privat användning. Tekniken använder sig utav en lager-på-lager metod för att tillverka olika objekt. LÄS MER

  3. 22. 3D Printed NovelZeolite 13X - Magnesium ChlorideComposites for Ammonia Storage

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Rafael Acosta Laisequilla; [2019]
    Nyckelord :Ammonia absorption 3D printing Zeolites;

    Sammanfattning : In today’s world regulations to reduce vehicle emissions are only gettingtougher, from said regulations the concept of a Selective Catalytic Reduction(SCR) unit was born, designed to provide a healthy dose of ammonia (NH3)to reduce the NOx compound into harmless components such as water andnitrogen. In this thesis novel approaches where investigated, by combiningthe fast physical absorption and desorption properties of a highly porous ma-terial such as zeolites with the high storage capacity of metal chlorides wecan potentially improve NH3 dosing in the low temperature operating range,such as when vehicles have just been turned on.

  4. 23. Design and Evaluation of a 3D Printed Ionization Chamber

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Caroline Boström; Olivia Messler; [2019]
    Nyckelord :3D printing; Ionization chamber; Gas-filled detectors;

    Sammanfattning : Ionizing radiation is often used within medicine for diagnosis and treatments. Because ionizingradiation can be harmful to the body, it is important to know how it affects the tissue. Dosimetryis the study of how ionizing radiation deposits energy in a material. LÄS MER

  5. 24. Motorized tensioner systemfor prosthetic hands

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Jonas Tjomsland; Felix Hardell; [2018]
    Nyckelord :Mechatronics; Haptics; Prosthetics; 3D Printing; Mekatronik; Haptik; Proteser; 3D Printing;

    Sammanfattning : Modern research in prosthetic devices and other assistive technologies are constantly pushing boundaries. While the technology is impressive, it is still inaccessible for the greater part of the people in need of it. Advanced devices are often extremely expensive and require regularly maintenance from professionals. LÄS MER

  7. 25. Direct pellet extruder developed for LEDC - 3D print with recycled materials

    Master-uppsats, Lunds universitet/Innovation
