Resumen

Biokomposit är ett material som har stor potential att ersätta plastprodukter i framtiden. Med ett innehåll av träfibrer och växtbaserad plast är det både biologiskt nedbrytbart och fullt möjligt att återvinna. I det här projektet undersöks materialet biokomposit i samklang med additiv tillverkning, 3D-print. Syftet är att undersöka materialets estetiska potential, och visa möjligheter inom en tillverkningsteknik som inte håller samma status som exempelvis formsprutning. Författaren vill framhäva det som många skulle se som defekter i en tillverkningsprocess, för att ge komplement till Studio

Resumen

The two projects covered by this thesis describe new ways to leverage modern advancements in additive manufacturing techniques in the field of biofabrication. The initial project was a proof-of-principle study which involved the selection, customisation and use of a commercially available stereolithography (SLA) 3D printer to produce synthetic structures using GelMA hydrogels for a cartilage fabrication process. The second topic investigated improving the accuracy, design processes and reproducibility of melt-electrospinning onto a rotating mandrel. This investigation advanced the process from

The world has recently witnessed the widespread of 3D printing technology. In the shadow of this development a new means of freezing time was born: 3D figurines. A 3D figurine is a mini version of oneself; a little sculpture manufactured by 3D Printers. These 3D figurines are sold for a profit by so called 3D Print Stores to consumers. For the production of such a 3D figurine one needs 3D Body Scanners. It is from the perspective of a producer of 3D Body Scanners that this master thesis was written.

Extrusion of the material from the print head is ensured by a screw conveyor, shaping of the material is carry out by a rotatably mounted nozzle provided with trowels. The dimensioning of the main elements of the print head is based on the parameters measured during tests with the older version of the print head and on the FEM analysis. The print head was manufactured and is able to extrude con

Resumen

The thesis deals with the determination of mechanical properties of materials used for 3D printing (ABS, nylon and PLA). Standardized samples produced using a 3D printer using the Fused Deposition Modeling method were subsequently used for mechanical testing. The work is also extended to determine the mechanical properties of samples made by Soft Tooling. For the production of Soft Tooling samples, polyurethane resins SG 2000 and SG 145 were used. Individual materials were analyzed by mechanical tests (tensile test and hardness test). Surface integrity parameters have also been determined for

Resumen

The thesis deals with the theory of 3D printing, materials for printing and bonding. It focuses on FDM printing and PLA material. It also compares gluing with other methods and deals with the distribution of adhesives, the gluing procedure and tests of glued joints. The work, based on literature studies, proposes an experiment to evaluate selected adhesives. The practical part contains a description, results and evaluation of the experiment. The evaluation of adhesives is based on tensile and shear strength.

It is usually difficult to see small defects, missing triangles, convex and other deformations of the grid in slicers. There are online services stlfixers that fix network models. They quickly fill in defects, but are limited by the size and number of triangles of the model. In this case, slicers "do not see" the smallest holes in the grid or one / two tri

Resumen

The master's thesis deals with the determination of mechanical properties of materials used for 3D printing (PLA, PETG, ABS, ASA). The theoretical part contains characteristics of polymer materials and describes testing of mechanical properties and additive technologies. In the experimental part, the standardized samples produced by the technology Fused Filament Fabrication were analysed using mechanical tests (tensile test and hardness test). Some of the examples were exposed to the selected factors of degradation. Selected parameters from mechanical testing (tensile strength, modulus of elas

The aim of this work deals with the design and manufacture of a device for mixing of magnetic beads in solution by magnetic field. It is based on my previous bachelor thesis, where the device was created for one microtube (one sample). In this following work, the three improved variants for mixing and separation of 96 samples at one time were designed. The first variant of device, derived from functional prototype from bachelor thesis, was manufactured. First, the magnetic circuit and power converter were designed. Subsequently, the device was manufactured just for one microtube due to functio

Resumen

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. Med dagens teknik går det att printa ut föremål av exempelvis metall, plast, betong och ett flertal andra material. Additiv tillverkning av betong ger möjligheten att skapa nya smarta konstruktionslösningar, vilket medför stora materialbesparingar och minskat materialspill. Produktionskostnader och hastighet kan också dra nytta av meto

Resumen

This two-part project undertaken at QUT and the University of Wurzburg focused on a 3D printing technology known as Melt-electrospinning. In the first part, a melt electrospinner device was designed and assembled to fabricate tissue engineering scaffolds. An air ioniser was then then used to investigate the effects of reduced surface charge on the scaffolds such as to improve the output and height of the printed structure. The goal of the second project was to fabricate scaffolds using an electro-active polymer capable of altering its shape when placed within an electric field.

A demonstration robot for conferences and fairs has been built from scratch. The demonstration robot is meant to create lasting impressions at the company booth at conferences or fairs. Thus, the robot needs traits that attract people to the booth and makes sure they remember that company. In this project, traits such as being able to move, do facial expressions and play audio have been developed. The robot has also been designed to draw as much attention as possible to the booth. This was achieved by building a robot that consists of a rolling sphere with a head that always remains on top. Al

Resumen

The outcome of my thesis is airy relief in the form of a spreaded Kyjov´s women's folk costumes. It is made up of embroidery and lace, which gets their original lightness without underlying substance.The white color, I have used, strenghts this feeling. All parts are printed by the ABS plastic. I follow the transformation of hand-made embroidery on the machine-made one with this. 3D printing is another entirely fictitious step for me. Just as the embroidery machine adjusts stitches according to their outline, as well as 3D printer has its own structure of applying material.
