  1. 1. Continuous Fibre Reinforcements in Injection Moulded Composites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Erik Björkqvist; [2023]
    Keywords : Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Abstract : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. READ MORE

  3. 2. UV Curable Polymers for use in Additively Manufactured Energetic Materials

    University essay from KTH/Fiber- och polymerteknologi

    Author : Alexis Delorme; [2022]
    Keywords : Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

    Abstract : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. READ MORE

  4. 3. Structure and Gait Optimizationof a Soft Quadrupedal Robot

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : David Danelia; Shuo Fu; [2021]
    Keywords : Soft robotics; mobile robots; quadrupedal robots; continuum actuators; 3D-printing; Mjuka robotar; mobila robotar; fyrfotarobotar; kontinuumställdon; 3D-skrivning;

    Abstract : Quadrupedal robots are mobile robots with four limbs. Compared with other mobile robots, quadrupedal robots are more capable of moving in complex environment. Specifically, softquadrupedal robots have the limbs that are flexible and more compliant with the environmentthan that of rigid quadrupedal robots. READ MORE

  5. 4. Closed-Loop Control of a 3D Printed Soft Actuator with Soft Position Sensors

    University essay from KTH/Mekatronik

    Author : Jakob Jansson; Mikael Sjöberg; [2021]
    Keywords : Soft Actuators; 3D Printing; Closed-Loop Control; Strain Sensor; Soft Gripper; Mjuka Ställdon; 3D-Skrivning; Återkopplad Kontroll; Töjningssensor; Mjukt Gripdon;

    Abstract : This thesis performs closed-loop control of a 3D printed soft bending actuator with feedback from a 3D printed strain sensor. This process utilizes the Finite Element Method (FEM) to design a bellow type pneumatic bending actuator that can handle pressures up to 4 bar. READ MORE

  6. 5. Development of a phantom for the verification of stereotactic arrhythmic radioablation treatment deliveries

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Lovisa Jessen; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Aim: Phantoms are used daily in the clinic for radiotherapy. As more realistic phantoms are requested, 3D printing could be used but the design of a realistic phantom is difficult. READ MORE
