  1. 11. 3D Printing Composites from Raw Materials

    Master-uppsats, Lunds universitet/Innovation

    Författare :Oscar Rundbäck Martinsson; [2021]
    Nyckelord :Additive manufacturing; Extrusion; Compounding; 3D-printing; Technology and Engineering;

    Sammanfattning : For the last decades, the subject of Additive manufacturing, also known as 3D-printing, has been rapidly developing in both the industrial and recreational fields. As new applications are discovered, materials and methods have to be researched and developed at the same pace to not stunt the creativity that 3D-printing brings out. LÄS MER

  3. 12. Modelling and Control of an Extruder Cooling System

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Christopher Fritzon; Nils Persson; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The thesis aims to develop knowledge of the physics and thermodynamics behind a nonlinearity in an air cooling system for an plastic extruder machine. To accomplish this, both nonlinear and linearized models were set up in Matlab and Simulink environments based on the laws of physics and thermodynamics. LÄS MER

  4. 13. Energieffektivisering av fabrik inom tillverkande industri : Utvärdering av åtgärdsförslag

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Linnéa Abrahamsson; [2021]
    Nyckelord :Extruder; Plast; Ventilation; Byggnad; Energiförluster; Energianvändning;

    Sammanfattning : June 1st, 2014, the law on energy audits of large enterprises was introduces as a way of promoting energy efficiency and to help fulfil the demands from the EU energy efficiency directive. One company that this law applies to is Talent Plastics in Gothenburg. In 2017 an energy audit was conducted at the company by WSP in Karlstad. LÄS MER

  5. 14. Fused deposition modeling of API-loaded mesoporous magnesium carbonate

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Andreas Abdelki; [2020]
    Nyckelord :Additive manufacturing; 3D-printing; Fused deposition modeling FDM ; Fused filament fabrication FFF ; Drug delivery; Amorphous drugs; Mesoporous magnesium carbonate; Upsalite; Cinnarizine; Hydroxypropyl cellulose HPC ; Hydroxypropyl methylcellulose acetate succinate HPMCAS ; Klucel ELF; AquaSolve LG;

    Sammanfattning : In this thesis, the incorporation of drug loaded mesoporous magnesium carbonate as an excipient for the additive manufacturing of oral tablets by fused deposition modeling was investigated. Cinnarizine, a BCS class II drug, was loaded into the pores of the mesoporous material via a soaking method, corresponding to a drug loading of 8.68 wt%. LÄS MER

  7. 15. Polymer rejuvenation of PET textile waste

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sabrina Kopf; [2020]
    Nyckelord :PET; recycling; textiles; molecular weight;

    Sammanfattning : Thermomechanical recycling of polyethylene terephthalate (PET) typically includes a decrease in the polymer´s intrinsic viscosity and therefore a reduction of the molecular weight. Consequently, thermomechanical recycling is usually a downcycling of the product. LÄS MER
