Hypothetical Question

The distance between Hemse church and the fields of Mästermyr on the Swedish Island of Gotland is about eight kilometers. The distance or rather the proximity between these two places is given importance in this filmed research article. In the 1930s, a farmer found a wooden chest in Mästermyr containing hundreds of forged tools and other artefacts. During a restoration of the Romanesque Hemse church in the 1890s, reused parts of a stave church were discovered in the wooden floor. The hypothetical question that is investigated in this study is whether the tools from Mästermyr were used in the construction of Hemse stave church in the early 1100’s? This filmed article analyzes and compares the traces of toolmarks in Hemse stave church and the woodworking tools from the Märstermyr finding. Through a forensic examination involving 3D scanning with structured light, 3D printing and reconstruction of tools and woodworking procedures, it is revealed that several toolmarks in the stave church correspond to the characteristics of woodworking tools in the Mästermyr find. The tool's shape, dimensions and mode of operation are traced in its negative imprint in the stave church’s oak wood.

Hydrodynamic Testing

Abstract The relevance of the work is determined by a fundamentally new direction of 3D printing in the manufacture of ship models for hydrodynamic testing. In this paper, we study the towing drag of a model of a small boat manufactured using additive three-dimensional printing technologies. Based on the dimensions of the 3D printers used and the technological parameters of working with them, as well as the design features of the test pool, small-sized vessels of a series of kayaks, kayaks and canoes, which are of sufficient length, but not too wide and high, were investigated as a prototype of the future model, which is ideal under the methods of additive manufacturing. A base of prototypes of vessels of this class has been compiled and a rationale has been given for the choice of the prototype vessel itself for research, including an analysis of the design of the vessels presented, the availability of design and technological documentation, as well as technological schemes for manufacturing the model. A 3D model of the vessel was developed, its optimization for 3D printing and analysis of geometric shapes for deviations from ITTC requirements. The study of deviations of the geometric shapes of the ship model from shrinkage deformations was carried out using 3D scanning with the development of a technological scheme for describing this process. When developing a 3D model, in the process of 3D printing, as well as processing the results of 3D scanning, modern software tools — FreeShip, Autodesk Inventor, Cloud Compare, and others — were used in the work. In the manufacture of the model, the new DPA adhesive compound formula was used, able to provide durable joints for PLA plastic products. It was found that the measurements prove the possibility of using 3D printing for the production of ship models for hydrodynamic testing, subject to all the nuances of the technology.

<p>Due to the economic advantage of mass manufacturing technology humans have designed a world of products built for the average body size and shape. This conformity of diverse body shapes to fixed 3 dimensional forms raises the question for this research; how can 3D scanning and additive manufacturing (AM) create a personal fit between an individual’s body and a product?  This question challenges a tool driven standardised approach to manufacture by exploring the interface between a person and a mass produced product, in this case a motorcycle rider and a motorcycle. By taking advantage of digital data and the tool-less build process of 3D printing, every object produced can be different, tailoring it to the customer’s individual aesthetic or physical fit.  This investigation into the space between the motorcycle and the human has produced a custom 3D printed seat designed for and inspired by the unique physicality of the individual rider. The following methods are employed. 3D scanning is used to obtain the geometry of the human form and motorcycle, 3D modelling and 3D printing to generate and evaluate ideas and concepts, and a pressure measurement system to evaluate the riders comfort and fit.  This new relationship between body and object, rarely seen in mass produced products, questions the way we design and make products with consideration towards digital personalisation and manufacturing efficiency.</p>
