The trademarks on clothes are 3D printed and transferred using PVC or TPU soft glue. The 3D soft glue I have seen is like the one made by Super Shadow 3D printing below. The effect is good.
The application fields of 3D soft glue are also very wide, such as: clothes, shoe uppers, hats, school bags, wallets, handbags, anti-counterfeiting trademarks, hang tags, watch straps, mouse stickers, etc.
