Die Cutting Machine

Popular among hobbyists and budding artists, die cutting machines, also known as craft plotters or cutting machines, are versatile tools for making decals, stickers, signs and cards. They are used for cutting various materials such as metal, paper and fabric into a variety of shapes and designs.

Design Challenges

With the growing interest in DIY activities, a huge online community of designers and hobbyists exists to share and exchange designs. To offer more versatility and the ability to create custom designs out of metal, paper and fabric, a modern die cutting machine needs:

  • A PC interface to enable the instant transfer of designs created with graphics design software
  • The ability to connect to the cloud to access thousands of cutting patterns and download them directly into to the machine
  • The ability to quickly and precisely cut thicker, heavier and more varied materials instead of just card stock or fabrics 

Microchip offers all the key embedded hardware components required to develop a state-of-the-art die cutting machine.
