3D prints on clothesare now created with more perfection



Embroidery and printing clothing company use several ways to print and all those available are additive, differing mainly in the way layers are built to create the final object. Not all 3D printers use the same technology. There are some methods that involve melting or softening material to produce the layers. Selective laser sintering (SLS) and fused deposition modelling (FDM) are the most common technologies using this way of 3D printing. Another method is when we talk about curing a photo-reactive resin with a UV laser or another similar power source one layer at a time. The most common technology using this method is called stereo lithography (SLA).


To be more precise, the additive manufacturing processes are divided into seven categories. These seven processes are Vat Photo polymerisation; Material Jetting; Binder Jetting; Material Extrusion; Powder Bed Fusion; Sheet Lamination; and Directed Energy Deposition. A 3D printer based on the Vat Photo polymerisation method has a container filled with photo-polymer resin which is then hardened with a UV light source.The most commonly used technology in this process is Stereo lithography (SLA). This technology employs a vat of liquid ultraviolet curable photo-polymer resin and an ultraviolet laser to build the object’s layers one at a time. For each layer, the laser beam traces a cross-section of the part pattern on the surface of the liquid resin. Exposure to the ultraviolet laser light cures and solidifies the pattern traced on the resin and joins it to the layer below.After the pattern has been traced, the SLA’s elevator platform descends by a distance equal to the thickness of a single layer, typically 0.05 mm to 0.15 mm (0.002″ to 0.006″). Then, a resin-filled blade sweeps across the cross section of the part, re-coating it with fresh material. On this new liquid surface, the subsequent layer pattern is traced, joining the previous layer. 

The complete three dimensional object is formed by this project. Stereo lithography requires the use of supporting structures which serve to attach the part to the elevator platform and to hold the object because it floats in the basin filled with liquid resin. These are removed manually after the object is finished.This technique was invented in 1986 by Charles Hull, who also at the time founded the company, 3D Systems.Other technologies using Vat Photo polymerisation are the new ultra fast Continuous Liquid Interface Production or CLIP and marginally used older Film Transfer Imaging and Solid Ground Curing And Inkminded is Best Embroidery printing clothing company in USA.
