Abstract
The invention relates to a filter made from an open porous solid material which is made from droplets that are arranged at one another and bonded together at contact portions through hardening, wherein open pores are provided between the droplets.
Claims10
A filter, comprising:
- an open porous permeable or semi permeable solid material,
- wherein the open porous solid or semi permeable material is made from hardened droplets which are made from a droplet material and arranged at one another in a uniform pattern and bonded together at contact portions through the droplet material,
- wherein open pores are provided between the hardened droplets, and
- wherein the open pores are connected with one another and with an ambient.

A filter, comprising:
- an open porous permeable or semi permeable solid material,
- wherein the open porous or semi permeable solid material is made from hardened droplets which are made from a droplet material and arranged at one another in a uniform pattern and bonded together at contact portions through the droplet material,
- wherein open pores are provided between the hardened droplets,
- wherein the open pores are connected with one another and with an ambient,
- wherein the droplets include solid particles, and
- wherein a plastic material is removed from the droplets and the solid particles are bonded together at contact portions through heating below a melting temperature of the solid particles to form the open porous and permeable or semi permeable solid material.
