In e-commerce, product returns and conversion rates are crucial. 3D models better communicate the product to the customer, making the shopping experience more exciting and the online shop more efficient. For a 3D online shop, 3D models of all products are needed. These can either be 3D modeled from scratch or created more cost-effectively and truer-to-life with 3D scanning.
We combine the advantages of photogrammetry and 3D CT scanning (computed tomography) to create a highly accurate color 3D scan. Photogrammetry provides the best possible color information, while computed tomography allows us to 3D-scan the object with unparalleled accuracy. Subsequently, the 3D scan data from both techniques are merged.
We created a 3D-printed 3D zoetrope to show the blossoming process of a flower. A real lily was 3Dscanned at various stages of bloom. From these 3D scans, we created a 3D animation. From the 3D animation, we 3D printed 15 lilies and arranged them on a round plate. We illuminated the rotating plate with a strobe light to create the illusion of blossoming lilies.
Wire EDM is a process for cutting metal. It is used to cut metal 3D prints from their base plate. When 3D printing on metal, the printed part becomes one with the base plate on which it is printed. To separate the two without damaging the part, a precise cutting process is needed. This is where wire EDM shines.
SLM is a 3D printing process in which metal powder is fused by laser, creating a new object layer by layer. SLM stands for (Selective Laser Melting), which means that the laser selectively melts the metal powder only where the solid material is needed. In the end, the finished object can be removed from the powder bed.

    We digitally repaired the broken clothes rail holder of an IKEA closet and then 3D-printed it in plastic. We first 3D-scanned the original broken part using a 3D CT scanner (computed tomography 3D scanner). Afterward, we reconstructed the 3D scan using reverse engineering and thus repaired it. The finished file was 3D-printed inside a laser sintering 3D printer.

    You only need a mobile phone and some free software to create a free 3D scan. The technique is called photogrammetry. We 3D-scanned the same part twice—once for free and once with a professional 3D scanner—then compared both 3D scans. The result: The free 3D scan has a deviation of only about 0.2mm compared to the professional 3D scan.

    Reverse engineering enables us to create a copy of an object. For this purpose, the part is 3Dscanned, then the 3D scan data is converted into a CAD format, and finally, the part is manufactured. All these steps result in noticeable deviations. If an error adds up over multiple steps, then we call this error propagation.
