METHOD FOR BORING A CYLINDRICAL SAMPLE FROM 3D-PRINTED STRUCTURE
A method to support a structure for boring and subsequent characterization tests which includes selecting and preparing a casting material, placing the structure, with a structure height, into the casting material which possesses a base side and a casting material height, and allowing for the casting material to set, creating a cast sample with a shape. The method further includes inserting the cast sample into a boring apparatus, boring and extracting a cylindrical specimen from the cast sample, and performing characterization test on the extracted specimen.
1 . A method comprising:
selecting and preparing a casting material;
placing a structure, with a structure height, into the casting material which possesses a base side and a casting material height;
allowing for the casting material to set, creating a cast sample with a shape;
inserting the cast sample into a boring apparatus;
boring and extracting a cylindrical specimen from the cast sample; and
performing a characterization test on the extracted specimen.
2 . The method of claim 1 , further comprising:
selecting a mold for the casting material; and
pouring the casting material into the mold.
3 . The method of claim 1 , wherein the casting material height is greater than the structure height and a layer of casting material resides between the structure and the base side.
4 . The method of claim 1 , wherein the structure is a 3D-printed structure.
5 . The method of claim 1 , wherein the shape of the cast sample is an orthotope.
6 . The method of claim 1 , further comprising:
storing at least one of the cast sample and the extracted specimen in an aqueous solution.
7 . The method of claim 1 , wherein the casting material is gypsum cement.
8 . The method of claim 1 , wherein the boring apparatus comprises:
a drill press;
a boring drill bit;
a vise; and
buffer material.
9 . The method of claim 1 , wherein the extracted specimen is cylindrical with a diameter of 1 inch and a height of 2 inches.
10 . The method of claim 1 , wherein the characterization test is a standardized test defined by a testing or standardization body.
11 . A cast sample with an associated shape, comprising:
a non-uniform structure and a casting material, wherein the non-uniform structure is at least partially enveloped by the casting material and the casting material is disposed to protect the non-uniform structure from damage by compressive forces and the casting material does not slip when constricted by a vice by nature of its material or shape.
12 . The cast sample of claim 11 , wherein the non-uniform structure is a 3D-printed structure.
13 . The cast sample of claim 11 , wherein the associated shape of the cast sample is an orthotope.
14 . The cast sample of claim 11 , wherein the casting material is gypsum cement.
15 . A system for extracting a cylindrical core from a non-uniform structure, comprising:
a boring apparatus comprising:
a drill press,
a boring drill bit, and
a vise;
a cast sample with an associated shape, the cast sample comprising:
a non-uniform structure and a casting material, wherein the non-uniform structure is at least partially enveloped by the casting material and the casting material is disposed to protect the non-uniform structure from damage by compressive forces and the casting material does not slip when constricted by a vice by nature of its material or shape;
inserting the cast sample into the boring apparatus; and
boring and extracting a cylindrical specimen of the non-uniform structure from the cast sample using the boring drill bit.
16 . The boring apparatus of claim 15 , further comprising a buffer material.
17 . The system of claim 15 , wherein the non-uniform structure is a 3D-printed structure.
18 . The system of claim 15 , wherein the casting material is gypsum cement.
19 . The system of claim 15 , wherein the extracted cylindrical specimen has a diameter of 1 inch and a height of 2 inches.
20 . The system of claim 15 , further comprising performing a characterization test on the extracted cylindrical specimen.
