Abstract

A fluorescence detection system includes a light source for coupling with a mobile device and software, having machine readable instructions loadable into memory of the mobile device and executable by a processor of the mobile device, capable of: activating the light source in coordination with capturing one or more images using a camera of the mobile device; analyzing an image captured with the light source on with an image captured with the light source off, to detect a shift of intensity within a predetermined color range within the images; and identifying and authenticating objects by measuring the intensity shift within the images.

Claims

1. A 3D printer with filament authentication, comprising:

a print engine for generating a 3D object using a filament of material; and

an infrared (IR) authenticator positioned to authenticate the filament before use by the print engine the IR authenticator comprising;

an IR generator for generating IR at a first wavelength; and

an IR detector for detecting fluorescence of a dye within the filament at a second IR wavelength;

wherein the authentication of the filament is based upon detection of the fluorescence at the second IR wavelength;

wherein operation of the print engine is based upon authentication of the filament by the IR authenticator.

2. The 3D printer of claim 1, wherein the print engine initiates authentication of the filament when the filament is installed into the 3D printer.

3. The 3D printer of claim 1, wherein the print engine initiates authentication of the filament periodically during operation of the print engine.

4. The 3D printer of claim 1, wherein configuration of the print engine is based at least in part upon the authentication of the filament.

5. The 3D printer of claim 1, wherein at least one parameter of the print engine is configured based upon the detected florescent response of the dyes within the filament.

6. The 3D printer of claim 1, wherein the detected fluorescent response of the dyes identifies a type of the filament.

7. A method for authenticating a filament used in a 3D printer, comprising:

projecting, within the 3D printer, an IR beam at a first wavelength onto the filament; and

detecting, in response to the IR beam, IR fluorescence at a second wavelength from a dye within the filament;

wherein the detected IR fluorescence indicates authentication of the filament within the 3D printer.

8. The method of claim 7, wherein the steps of projecting and detecting are repeated periodically during operation of the 3D printer.
