3d Printing [2006-2011]
Macsys was founded as a General Partnership (Dutch V.O.F.) on 13 October 2006 by André Schalkwijk and Marcel Alfons. The name Macsys is inspired by CAM software Cimatron, where MACSYS stands for Machine Coordinate System. Macsys uses SketchUp software to transform architectural 2d drawings into 3d surface models. The 3d surface models are fed into Z-Corp printers to create tangible solid models or maquettes. Z-Corp printers use inkjet-technology to create full color models, making them ideal for visualization.
Traditionally, architectural models are handmade using various materials. These materials have a look and feel that is close to the finished building, something that can not be achieved with 3d printing. The benefit of 3d printing is speed. A virtual 3d model is created faster and in finer detail then hand crafted models, especially if the building design is available digitally. Because 3d printed models are build up in layers, the surface finish is inferior to traditional models. The surface finish however can be improved by sanding or bead blasting.
The first commercial project for Macsys was creating a colored 1:50 scale model of a villa in Dronten. Details include; tiled roof, water drainage pipes and muntin windows. At the time of modeling this project, there was no 'shell function' available in SketchUp, meaning that creating the correct wall thicknesses had to be done manually. A very tedious and time-consuming task, which is fully automated in most solid modelers. The second project was a huge jump in complexity. It was requested to build a scale model of a 900 m² mansion. It was requested to build the model with an open roof, making it possible to view the internal layout. Since the scaled model was larger than the available 3d printer, the model required sectioning. Building plans for the 30m x 30m mansion were available in AutoCad 2d format. The mansion includes: a swimming pool, sauna, fitness room and underground parking. Macsys's third model was a challenge in terms of detailing. The unique house design includes an elevation, round structure, high detail stairs, pillars and balcony. Since printed models are relatively weak, scaling was done non-uniform, so that the finer details are printed somewhat bigger and are thus stronger.
After the first projects were successfully launched, demand for models increased. That is why Macsys partnered with a SketchUp modeling firm based in Thailand. This allowed Macsys to increase its design capacity and take on more work and more challenging projects.
