1. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique
University essay from KTH/HållfasthetsläraAbstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

2. Experiments, analysis and an application of 3D-printed gyroid structures
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : The thesis investigates the mechanical properties of gyroid structures through various experiments and simulations. Gyroid structures consist of an intricate mesh of surfaces and can differ in density and cell size. The mechanical properties of the gyroid structure are inevitably dependent on the density.

3. “Once upon a time there was a boy named Carl” : A study on the effects of scaffolding on the performance of students with reading and writing difficulties
University essay from Karlstads universitetAbstract : The aim of this study is to investigate what difficulties Swedish students with reading and writing difficulties may encounter when they write texts in English. A teaching experiment was done to see whether scaffolding, a process where the teacher shows the overall structure of e.g. READ MORE

4. Investigation of support structures of a polymer powder bed fusion process by use of Design of Experiment (DoE)
University essay from KTH/LättkonstruktionerAbstract : In this thesis, support structures of a polymer powder based process called XXXXXXXX™ are examined. These structures are crucial for most additive manufacturing processes. The effects of several factors on five industrially important characteristics of support structures are examined by use of the Design of Experiment (DoE) method. READ MORE

5. Topology Optimization for Additive Manufacturing
University essay from Lunds universitet/HållfasthetsläraAbstract : Topology optimization answers the question "How to place the material within a prescribed design domain in order to obtain the best structural performance? " and the design obtained is usually complex. Additive manufacturing comes with a well known design freedom and the design provided by topology optimization can be manufactured without as many constraints as conventional manufacturing methods.
