3D printed gingerbread house baked
William Kempton, design researcher at the Academy of Architecture and Design in Oslo, created the world's first 3D printed gingerbread house. The gingerbread house was printed by a DeltaWASP 20 40 clay 3D printer. Christmas is coming, gingerbread house as an element of Christmas, it will certainly be quite high in the coming weeks. Scandinavian gingerbread is the most famous. Although the gingerbread is not from there (Gingerbread from Armenia), the craftsmanship of Swedish gingerbread is quite high. Since the German immigrants brought the gingerbread there in 1200, the people there have continued to carry forward this culinary process. On the road from Sweden to Norway on the city of Bergen, you can even see an entire Gingerbread City with gingerbread houses, trains and cars. Gingerbread City in Bergen, Norway When we heard the gingerbread house printed by William Kempton 3D, a researcher at the Oslo School of Design in Norway, we were quite surprised! Indeed, no place is more suitable for 3D printing gingerbread houses than Norway? Kempton accepted his students' advice after using clay for many 3D printing projects: replacing the clay with gingerbread and treating the gingerbread with a DeltaWASP 20 40 clay 3D printer. “It sounds simple, but the first gingerbread print has gone wrong,†Kempton said. “First, the gravity problem is one aspect. Second, the material becomes very soft as soon as it is heated. If you have made a gingerbread house I know that I have to bake the gingerbread first and then stick them up. However, this is not the way I want to make a gingerbread house." The DeltaWASP 20 40 3D printer can handle a wide variety of materials, but gingerbread does not. To make the gingerbread house, the researchers equipped the machine with a liquid deposition modeling (LDM) extruder. But in the early days of the experiment, the gingerbread house collapsed as soon as it was printed. Later, Kempton added a custom extruder nozzle with a heater that prints at custom temperatures. Kempton said that he started using the commonly used gingerbread powder and added more flour and cornstarch to make the gingerbread harder. The alcohol is then added to make the mixture flow more easily. Therefore, the hardness of the material is quite important. The Kempton3D printed gingerbread house is based on the Norwegian wooden church Borgund kirke. It is 22 cm high and requires some support structure inside. “The 3D printed gingerbread house is still in the experimental stage, and in the future, people may be able to make gingerbread buildings with their own ideas,†Kempton said.

This kind of wind turbine is vertical axis, with Maglev PMG generator usually, it's very quiet and smoothly when rotating. It could star moving when the wind is very gentle because of maglev. And it's very quiet so you can install it on rooftop, it won't disturb your home and your neighbours. Besides, due to the vertical axis, the design could be more creative and openness compared with normal horizontal wind generators. However, the efficiency of vertical wind turbines is not very good, around 15% ~ 50% normally, some special design could up to 50%~75%.
