# Human Heart Subject Area: Science Learning Objectives: Students will learn about the anatomy of a human heart. \ \ Materials Needed: One computer, one Micro or Micro+ 3D printer, and one 250ft 3D Ink filament spool (PLA or ABS-R3 recommended) per 2-5 students. Brief Description: Students will print three different cross sections of an anatomical human heart and identify the different components of the human heart. To Prepare: Students will need a computer that has the M3D software on it. We recommend one printer per every 2-5 students. The Micro or Micro+ 3D printer will need to be plugged into both the wall and the computer. Each printer will need to have a 250ft spool feeding into the external port. A spool holder is also recommended. If you need assistance with any of the above please see our guides at support.printm3d.com. Lesson Plan: 1\. Students will go online to and download the three models. 2\. Upload the models to M3D software and print them. 3\. Once all the models have finished printing, students can use them to examine and identify the different components of a human heart. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
