Full textSolid Free Form Fabrication is an additive manufacturing process which is bound to the principle of building up details in a layer by layer fashion. An important application of this method is the production of prototypes. This, depending on a variety of factors, first and foremost the reduction of time to market, but also Solid Free Form Fabrications possibilities to do relatively complex geometries that would otherwise not have been able to be produced. The company may experience significant benefits of using prototypes in their production, and the purpose of these prototypes should be sorted out before the actual production. The work that is involved in manufacturing of prototypes should be structured and and planned, this planning should ultimately lead to a prioritization and also a sorting of the requirements that will be placed on the prototype. Thereafter the company is enabled to choose a FFF-method which is suitable for the purpose. For the choice of the FFF-method for manufacturing in plastics, there are essentially five different methods. These are Stereolitography (SLA), Selective laser sintering (SLS), 3D Printing (3DP), PolyJet and Fused deposition modeling (FDM). The different FFF methods do not provide the same results on the product. The results vary in areas such as durability, surface finish and aesthetics. The choice of material is of great importance due to the fact that the properties of the material must meet the properties required in the prototype. Useable materials vary for each method, so the choice of material is strongly associated with choice of method, which one must be aware in order to create a appropriate prototype. Also differences in how large prototypes that can be produced and the cost of each method are factors that should be factored into the company's choice of production. The choice of method therefore quickly becomes complex. By evaluating the demands made on the prototype, and compare these with the properties of materials and machine performance, you can decide which method is appropriate. It is, in other words, impossible to name a “best method”, this varies depending on situation and prototype. How vendors of FFF-machines and manufacturers of prototypes in plastic are thinking and guiding their clients follow a clear pattern. The industry also maintains the fact that prototypes should have a well-defined purpose, that is defined by the required properties of the prototype, which is satisfied by the choice of materials and FFF-method. The conclusion of this is that there is no best practice for manufacturing prototypes in plastic using FFF-methods. Each and every prototype demands a individual analysis and depending on the required demands on the prototype, a best method can be presented for just that single prototype.

Full textThis degree project concerns the product development of a new transport solution for internal transport of compressors, at the engine production at Volvo Cars Skövde. Today's transport solution consists of plastic trays that are difficult to handle by the assembly personnel and has a low transport capacity. A future planned volume increase in production sets demands on logistics efficiency related to this transport. Volvo Cars wants to develop a transport solution that has higher capacity while focusing on better ergonomics and efficiency in the assembly line. The thesis covers the product development process from identification of customer needs to prototype manufacturing. Customer needs were identified through interviews with relevant staff and observations of today's working procedures. Based on this, customer requirements and requirements specifications were compiled. A number of new concepts were generated using creative methods. The concepts were then evaluated through an evaluation matrix where the concepts are compared to each other based on how well they fulfilled the customer needs and specified requirements. A final concept where then brought into the detailed design phase to be modelled in CAD. Drawings were made to engineer a functional prototype that was later evaluated in production. The new concept consists of a 3-leveled carrier with 8 compressors per level. The compressors are loaded on folding shelves that allow access with a transverse lift from above. The new design gives a 3 times higher capacity, as well as more efficient transport and handling at the assembly line, through a reduction by 50 percent of the manual handling. Also the ergonomics have improved since manual handling of the packaging in the assembly and by truck driver is minimized.

Full textAlthough protective equipment has been developed that protects the brain against dangerous rotating kinematics in several areas, no equipment is yet available to protect boxers against this type of violence. The purpose of this work was to make Olympic boxing and training safer. The goal was to develop a glove that reduces the strain in the brain by at least 20 %. In this work, a number of boxing gloves with implemented sliding layers were developed and tested, which would reduce the strain in the brain that occurs when the head is subjected to rotational kinematics. In the tests a linear impactor was used, which hit the gloves against a test head. The test head collected data using nine accelerometers. Two of the prototypes reduced the strain by more than 20% in one or more tests, but they lacked in usability. None of the prototypes met all objectives and therefore no prototype can be recommended for further development, but it can be stated that there is potential in the basic idea.
