CAD geometries like NURBS surfaces are better at representing these curves and are easier to edit. This is because mesh formats like STL interpret 3D models as an assortment of polygons, whereas actual pieces of jewelry tend to contain smooth, curved surfaces - not dozens of tiny triangles. Here are a few other jewelry 3D scanning solutions from lesser-known manufacturers:Īfter obtaining a 3D model from a 3D scan, jewelers may need to reverse engineer the mesh file into a new CAD format. When a jewelry 3D scanner has completed scanning, its software creates a 3D mesh file (in STL file format, for example) of the piece of jewelry.ģD jewelry models are then commonly exported to a CAD software platform where the jeweler can edit or rework the piece, share it online, or simply store it digitally for future reference.Ĭontact manufacturer Get a quote Add to comparison Alternatives (other 3D jewelry scanners) Many of them enable one-click 3D scans and, thanks to auto-rotating tables, there is very little need for manual intervention. Jewelry 3D scanners are packaged with 3D scanning software on which the user can launch 3D scans, operate the automatic turntable, and adjust scanning parameters (e.g. In most cases, the user will have to flip the piece over in order for the scanner to capture the previously hidden surfaces. ![]() The most detailed side of the piece should face upwards, where there is no physical contact with the turntable. automatic turntable, multi-axis turntable), allowing the scanner to view the piece of jewelry from as many angles as possible. ![]() Most jewelry 3D scanners use an automatic rotating table (a.k.a. This problem can be mitigated by spraying the jewelry with a temporary or washable matte coating ( 3D scanning spray). Structured light patterns become distorted if reflected by the metal object. Left untreated, jewelry is difficult to scan, because a 3D scanner’s optical hardware has trouble processing shiny or reflective surfaces. Here’s a deeper look into the major steps linked to 3D scanning jewelry. Structured light technology with blue LED patternsĪ typical 3D jewelry scanning workflow combined with 3D printing and casting methods.Automated thanks to a rotating table with one or multiple axes of movement.Desktop format with an enclosed or partly enclosed scanning area.To recap, most jewelry 3D scanners feature the following characteristics: The result is a 3D CAD model that can be modified, re-used, sliced for 3D printing, etc. Meanwhile, a camera captures these deformed patterns, which are then processed by the scanner’s software to determine the jewelry’s precise geometry. These patterns visibly deform according to the object’s surface and contours. Structured light 3D scanners feature a light-emitting device (often a blue LED light) that projects a series of patterns onto the surface of the piece of jewelry. In terms of technology, the majority of jewelry 3D scanners use structured light 3D scanning methods. ![]() Hence, minimal manual input is required, and jewelers can 3D scan their objects at the click of a button. Desktop jewelry 3D scanners almost always feature an automatic turntable, or auto-rotating table, on which the piece of jewelry is placed to be scanned.īasic turntables only rotate at 360°, while more advanced, multi-axis turntable systems are able to tilt from side to side with multiple degrees of freedom. Most jewelry 3D scanners are enclosed or partly enclosed desktop machines that offer ideal lighting conditions. This brand is a certified partner from our network.
