Problems solved by technology
[0005] These printing methods are time consuming to perform and can take days or weeks to produce objects of reasonable size
This problem is exacerbated for complex objects with intricate components
This significantly reduces the usefulness of 3D printers and is currently one of the main obstacles preventing mass adoption of 3D printing in consumers and industry

Embodiment Construction
[0036] Referring to FIG. 1 , a schematic diagram of a conventional 3D printing device 10 known in the art is shown. The device 10 comprises a substrate 12 with an operating surface 14 on which a printed object is to be produced by 3D printing.
[0037] Apparatus 10 also includes a supply hopper 16 that deposits a monolayer of powder 18 onto operating surface 14 .
[0038] An energy gun 20 , typically a laser or electron gun, fires an energy beam 22 onto the powder layer 18 , causing the powder layer 18 to selectively melt or sinter to form the individual layers of the 3D object. This process is repeated to add additional layers and build the object incrementally until it is complete.
[0039] refer to figure 2 , which shows a schematic diagram of the 3D printing device 24 according to the first embodiment of the present invention.
[0040] The apparatus 24 comprises an operating surface 28 , at least one supply hopper 30 for depositing a layer 32 of powder 34 onto the opera...

A printing apparatus for printing a three-dimensional object comprising an operative surface, at least one supply hopper for depositing layers of powder onto the operative surface and an energy sourcefor emitting at least one energy beam onto the layers of powder. The supply hopper and energy source are configured such that when a topmost layer of powder is being deposited onto an underlying layer of powder on the operative surface, the direction travelled by the supply hopper when depositing the topmost layer is different to the direction travelled by the supply hopper when depositing the underlying layer, and at least one energy beam is emitted onto the topmost layer and at least one further energy beam is emitted onto the underlying layer, simultaneously, to melt, fuse or sinter the topmost and underlying layers.
Description
technical field [0001] The invention relates to a 3D printing method and equipment. [0002] More specifically, the present invention relates to a 3D printing method and apparatus suitable for high-speed manufacture of objects. Background technique [0003] 3D printed parts, manufactured by laying down successive thin layers of material from a three-dimensional (3D) digital image, create physical objects. [0004] Typically, these 3D printed parts can be manufactured in a number of ways, such as selective laser melting or sintering, which operate through a powder bed on which a beam of energy is projected to melt the top layer of the powder bed and cause it to weld to the substrate or base plate. This melting process is repeated to add additional layers to the base plate to incrementally build up the part until it is fully fabricated. [0005] These printing methods are time-consuming to perform and can take days or weeks to manufacture objects of reasonable size. This p...
