Embodiment Construction

[0128] Those skilled in the art should realize that the aspects described herein can be embodied as a method of manufacturing part 1 , a pressing system, or an additive manufacturing tool.

[0129] The invention defines a method for producing a part 1 layer by layer using additive manufacturing techniques. Basically, the method consists of the following steps:

[0130] - printing the part 1 together with the elastomeric casing 2 formed thereon, leaving a material-free gap between the part and the elastomeric casing, the elastomeric casing comprising at least one opening 2.1;

[0131] - Heating the integral part of the printed part 1 and the elastomeric casing 2 or maintaining the operating printing temperature;

[0132] - applying a vacuum through at least one opening 2.1 of the elastomeric sheath 2, causing the elastomeric sheath to deflate, thereby applying pressure to the printed part 1; and

[0133] - Keeping the printed part 1 under vacuum and heat during a predetermine...

Abstract

The invention relates to a method for manufacturing a part layer-upon-layer using an additive manufacturing technology. The method comprises the following steps: printing the part together with an elastomeric enclosure shaped thereto leaving a gap free of material therebetween, the elastomeric enclosure comprising at least one opening; heating the ensemble of the printed part and elastomeric enclosure or keeping an operating printing temperature; applying vacuum by the at least one opening of the elastomeric enclosure so that the elastomeric enclosure deflates thus exerting pressure to the printed part; and maintaining the printed part under vacuum and heat during a predefined time. The invention also relates to a pressing system for printed parts manufactured layer by layer using additive manufacturing techniques.

Description

technical field [0001] The invention belongs to the field of manufacturing, especially the field of manufacturing parts by additive manufacturing technology. More specifically, the invention has particular application in the manufacture of printed parts with complex shapes for structural applications. Background technique [0002] In the past, aircraft parts with structural applications have been made from aluminum alloys. Over the past few decades, with the development of composite manufacturing techniques, such structural parts have been manufactured using different techniques, such as co-bonding or co-curing of carbon fiber reinforced plastic (CFRP) component parts. [0003] However, all of these manufacturing techniques require components to go through various stages of manipulation in order to separately manufacture the different component parts that are then assembled together. This is a time consuming process and predetermines the production rate of the aircraft. A...
