Abstract

Official abstract text for this publication.

A three dimensional biological scaffold structure that includes a biologically compatible material that forms walls of multiple pores. The pores have a range of pore sizes including a pore size of less than 50 μm and a pore size of greater than 100 μm and also including pores having one or more intermediate pore sizes between 50 μm and 100 μm. The pores occupy more than 50% of a volume of the scaffold structure.

First claim

Opening claim text (preview).

The invention claimed is: 1. A three dimensional scaffold structure, comprising: at least one freestanding overhang region, comprising: an elongated first portion comprising a biologically compatible material that forms walls of multiple pores that occupy more than 50% of a volume of the first portion, the first portion having a first end and a second end, the first end attached to a base and the first portion extending away from the base, at least a portion of the pores having a pore size of less than 50 μm; and an elongated second portion comprising the biologically compatible material that forms walls of multiple pores that occupy more than 50% of a volume of the second portion, the second portion having a first end and a second end, the first end of the second portion attached to the second end of the first portion, the second end of the second portion being free, the second portion overhanging the base and oriented at an angle between about 60 degrees and about 120 degrees with respect to the first portion, and at least a portion of the pores having a pore size of less than 50 μm. 2. The structure of claim 1 , wherein a ratio of a length of the second portion to a length of the first portion is at least 1. 3. The structures of claim 1 , wherein at least a portion of the pores of the first portion and the second portion have pore sizes greater than 100 μm and at least a portion of the pores of the first portion and the second portion have pore sizes between 50 μm and 100 μm. 4. The structure of claim 1 , wherein the structure comprises artifacts indicative of a printing process.
