1. 26. FILAMENT EXTRUSION USING RECYCLED MATERIALS : Experimental investigations on recycled Polylactic Acid (PLA) materials

   University essay from Högskolan i Halmstad/Rydberglaboratoriet för tillämpad naturvetenskap (RLAS)

   Author : Dennis Johnson; [2020]
   Keywords : 3D printing FDM ; Filament Extrusion; Recycled PLA.;

   Abstract : 3D printing or additive manufacturing is a process of building threedimensional solid object from a digital file. In additive processes, an object is formed by laying down successive layers of material until the object is created. The most commonly used materials for 3D printing are PLA (Polylactic Acid) and Acrylonitrile Butadiene Styrene (ABS). READ MORE

3. 27. Development of polymer based composite filaments for 3D printing

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Elin Åkerlund; [2019]
   Keywords : 3D-printing; fused deposition modeling FDM ; composite filaments; biocompatible materials; biodegradability; medical applications; scaffold materials; poly lactic acid PLA ; polycaprolactone PCL ; hydroxyapatite HA ; mechanical properties; thermal stability; chemical composition; morphological characterization; accelerated degradation study; polymer degradation behavior;

   Abstract : The relatively new and still growing field of 3D-printing has opened up the possibilities to manufacture patient-specific medical devices with high geometrical accuracy in a precise and quick manner. Additionally, biocompatible materials are a demand for all medical applications while biodegradability is of importance when developing scaffolds for tissue growth for instance. READ MORE

4. 28. FrankZlicer : Direct slicing using arcs

   University essay from Mittuniversitetet/Avdelningen för data- och systemvetenskap

   Author : Johan Franzén; [2019]
   Keywords : FDM; Additive Manufacturing; 3D-printing; CAM; STEP; G-Code; Arc; Slicer;

   Abstract : 3D printing a CAD modelnormally requires conversion into a polygon mesh, usually an STL-file, in orderto be able to load the model in the slicer. This conversion destroys roundsurfaces and replaces them with flat surfaces. Slicing a polygon mesh resultsin one or more polygons, consisting of a number of straight lines. READ MORE

5. 29. Summation By Parts Finite Difference Methods with Simultaneous Approximation Terms for the Heat Equation with Discontinuous Coefficients

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Niklas Kåhlman; [2019]
   Keywords : Finite Difference Method; FDM; Summation By Parts; Simultaneous Approximation Terms; SBP-SAT; Heat Equation; Poisson s Equation; Discontinuous Coefficients; Piecewise Constant Coefficients; Convergence; Dual Consistency; Stability;

   Abstract : In this thesis we will investigate how the SBP-SAT finite difference method behave with and without an interface. As model problem, we consider the heat equation with piecewise constant coefficients. The thesis is split in two main parts. READ MORE

6. 30. Investigation on Filament Extrusion of Thermoplastic Elastomer (TPE) for Fused Deposition Modeling

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Wang Zicheng; Mohammad Nouri; [2019]
   Keywords : Filament Extrusion; Thermoplastic Elastomer; Fused Deposition Modeling;

   Abstract : This thesis is an investigation of the TPE filament for Fused Deposition Modelling (FDM) manufacturing method. All the investigations aim to optimize the quality of the filament in order to make Thermoplastic Elastomer (TPE) material possible for FDM manufacturing method. READ MORE
