ANTISEPTIC 3D PRINTING FILAMENT

Abstract

The antiseptic 3D printing filament contains the following coaxial layers arranged radially outside-in: an antiseptic layer, a color layer inside and next to the antiseptic layer, a support layer inside and next to the color layer, and a resin layer inside and next to the support layer. The antiseptic layer, the color layer, and the support layer are melted and joined to the resin layer with a temperature between 100 and 500 degrees Celsius and the filament diameter is between 0.80 and 3.20 mm. When an object is produced from a 3D printer using the filament, the produced object is antiseptic without additional coating or spraying antiseptic material, thereby reducing production time and effort. The filament is also prevented from contamination with prolonged antiseptic capability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims

[0016] As shown in FIGS. 1 and 2, an antiseptic 3D printing filament 6 according to an embodiment of the present invention contains the following coaxial layers arranged radially outside-in.

[0017] An antiseptic layer 1 is the outmost layer.

[0018] A color layer 2 is inside and next to the antiseptic layer 1. The color layer 2 is made of toner or color masterbatch, and is colorless or has one of the color black, purple, white, green, orange, silver, blue, pink, yellow, and red.

[0019] A support layer 3 is inside and next to the color layer 2. The support layer 3 is colored due to the configuration of the color layer 2.

[0020] A resin layer 4 inside and next to the support layer 3. The antiseptic layer 1, the color layer 2, and the support layer 3 are melted and joined to the resin layer 4.

[0021] As shown in FIGS. 3 and 4, when an object 7 is produced from a 3D printer 5 using the filament 6, as the filament 6 contains the antiseptic layer 1, the produced object 7 is antiseptic. The antiseptic layer 1 can be customized to have a specific antiseptic effect. During the forming of the filament 6, the melting temperature is between 100 and 500 degrees Celsius, and the filament diameter is between 0.80 and 3.20 mm.

[0022] As shown in FIG. 4, the object 7 produced from the 3D printer has the antiseptic layer 1 as its surface so that the object 7 is capable of antisepticising.

[0023] As shown in FIG. 5, an antiseptic 3D printing filament according to another embodiment of the present invention contains an antiseptic layer 1a, a support layer 3a, and a resin layer 4a, arranged coaxially and radially outside-in. During the forming of the filament, the melting temperature is between 100 and 500 degrees Celsius, and the filament diameter is between 0.80 and 3.20 mm. Its difference from the previous embodiment is that there is no color layer in the present embodiment. In other words, the filament of the present embodiment is colorless.

[0024] Compared to the prior art, the present invention has the following advantages.

[0025] Firstly, the filament's antiseptic layer allows the produced object to be antiseptic after production without additional coating or spraying antiseptic material, thereby reducing production time and effort. The filament is also prevented from contamination with prolonged antiseptic capability.

[0026] Secondly, the antiseptic layer can be customized to have a specific antiseptic capability.

[0027] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
