AI Technical Summary

Problems solved by technology

However, the disadvantage of this approach is the lack of adhesion due to heat buildup and undesired thermal shrinkage and the surface or texture imparted by the structured platform
[0005] The service life of printed surfaces from the above methods is often undesirably limited

[0073] Method of manufacturing modeled articles for evaluating 3-D printability

[0074] Adhesive tape (available from 3M Company, St. Paul, MN under the trade designation "3M POLYESTER DOUBLE COATED TAPE ST-416P") was laminated to the back of the 3-D printed substrate. The 3-D printed substrates had a front side with a 3-D printed surface prepared according to the Examples and Comparative Examples described below. This 3-D printed substrate with adhesive tape on the back was applied to a 3-D printing table using a silicone rubber roller. The original model design to be 3-D printed was designed using computer-aided design (CAD) software (available under the trade name "AUTODESK INVENTOR 2013"). The CAD-designed article to be 3-D printed is a square tray with side walls and corners, such as Figure 4 shown schematically.

Abstract

The invention discloses a method for three-dimensionally printing an article onto a surface.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 296877, filed February 18, 2016, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Three-dimensional ("3-D") printing techniques are known in the art (see, e.g., U.S. Patent No. 5,939,008 (Comb et al.)), and offer cost advantages and manufacture some articles compared to, e.g., conventional molding processes (including prototype models). In some forms of 3-D printing (for example, available under the trade designation "MAKER BOT AND 3-D SYSTEMS" from Stratasys, Eden Prairie, MN), plastic is printed layer by layer Nozzle extrusion that tracks the cross-sectional geometry of the part. Build materials are usually supplied in filament form. The nozzle contains a heater that keeps the plastic at a temperature just above its melting point so that the plastic flows easily through the noz...
