Could a multicolor SLA 3D printer be coming shortly? XYZPrinting data files patent

certification

A patent for an SLA 3D printer capable of producing multicolor objects has emerged. Filed by Taiwanese 3D printer company XYZPrinting in June 2018, the doc information a proposed “auto-coloring technology” from the corporation. Made for vat polymerization, the creation would be an market first, even though binder jetting and FDM/FFF are by now streaks ahead.

Comparing SLA to shade binder jet and FFF techniques in the patent, XYZPrinting states that the method’s capacity of only 3D printing certification “monochromatic 3D bodily models” leaves place for “more effective solutions.”

From – 15+ machines in 6 many years

A division of Kinpo Electronics Inc., XYZPrinting was started in 2013, 1st as a service provider of desktop 3D printers. In 2017, the business quickly expanded its 3D printer selection to encompass SLS, binder jet and DLP capabilities for the industrial industry. At this time, across the two desktop and industrial, the company’s 3D printer variety spans all-around 15 various equipment.

In the desktop assortment, XYZ makes the Nobel collection of SLA units, and da Vinci 3D printers which acquired a color edition in 2017. The XYZPrinting da Vinci Coloration 3D printer operates employing FFF technologies. Inside the print bed nevertheless, a inkjet head has been additional which sprays plastic layers with droplets of colour.

Layer-by-layer, pixel-by-pixel color

In the proposed SLA method from XYZ, coloration will be added by a coloring module put in along with the mild module. In this instance, it could be assumed that the resin in the process would be distinct, colorless and, comparable to the da Vinci Shade, unique tones are included through a liquid spray. It is not clear even so if, or how, XYZ will repair exact pixels of coloration, making it feasible to achieve practical depth as in colour FFF  objects. It could also be that the procedure achieves unique shades of predetermined shade.

Expected hues for the object are identified on a layer-by-layer basis, looking at each individual pixel of shade in that layer. As comprehensive in the doc, “each layer of the colour print info is a 2D coloration graphic […] according to pixel value of just about every pixel of the object print knowledge the step is configured to color at the corresponding positions of the slice bodily model according to the pixel value of every pixel of the shade print knowledge.”

Coming quickly?

Full facts of XYZPrinting’s SLA color 3D printing certification method are specific in United States Patent Software 20190210275.

Peng-yang Chen is mentioned as the technology’s sole inventor, and has been credited with a series of other IP filing for XYZ like “Three-dimensional printer and a 3-dimesnional printing module thereof” flied December 2018.

No facts at the moment exists to propose that XYZPrinting is scheduling to consider this SLA challenge to fruition. In truth, if each patent came true we could currently have traveling cars by now. On the other hand, the company’s established urge for food for innovation, and its track document for developing machines should not be underestimated.
