2. OUTLINE  Motivation  Introduction  Problem Statement  Assumptions  Proposed Solution  Results  Demonstration  Conclusion  Future Work 2

3. MOTIVATION  I wanted to attempt a different method of creating PCBs due to the large cost to have several manufactured.  I wanted a custom housing to place these PCBs in after I mill them with a CNC. 3

4. INTRODUCTION  I intended to create a machine that would be able to do the job of a CNC/3D printer hybrid that is on the market, but at a lower cost while still providing adequate performance.  This is a project that can easily become part of the networking, engineering, programming, and electronics fields. 4

5. PROBLEM STATEMENT There are several problems regarding the CNC/3D printers on the market today:  They are outrageously priced  whiteAnt 3D/CNC whiteAnt 3D/CNC  The print area is small for most machines in the $1000 price range; roughly 6in^3, give or take a few inches.  With a small print area comes the inability to print large parts. This leads to separating large components into smaller parts, which leads to decreased stability in the part. 5

6. ASSUMPTIONS  The project needs to remain functional and provide excellent performance while keeping the costs as low as possible.  This project is for individuals interested in CNC and/or 3D printing, whether it be how everything works mechanically, electronically, or both.  This project is intended to be a proof of concept that a CNC/3D printer hybrid is possible at a low cost. 6

7. WARNING!!!!  I am not liable if you waste your money or hurt yourself in the process of recreating this project. Do so at your own risk.  Thank You. 7

8. PROPOSED SOLUTION Lets tackle this project in several steps: 1. Electronic Setup 2. Machine Base Construction 3. 3-Dimensional Axis Movement 4. Motor Control 5. Swappable Components 6. 3D Printing Element Controls 8

9. ELECTRONIC SETUP 9

10. MACHINE BASE CONSTRUCTION 10

11. 3-DIMENSIONAL AXIS MOVEMENT 11 X-Axis Construction

12. 3-DIMENSIONAL AXIS MOVEMENT 12 X-Axis Complete, Starting Y-Axis Testing Y- Axis Movement

13. 3-DIMENSIONAL AXIS MOVEMENT 13 Y-Axis Complete, Currently Mounting the Z-Axis to the Y-Axis for vertical movement

14. 3-DIMENSIONAL AXIS MOVEMENT 14 Setting up the Z-Axis movement block. It must be offset since we use 1 slide for the Z-Axis

15. MOTOR CONTROL 15

16. SWAPPABLE COMPONENTS 16 Standard mount design to place on Z-Axis and attach drills or extruders. Made to easily swap components.

17. SWAPPABLE COMPONENTS 17 Adapter mount is on the left, and fully assembled attachment mount is below.

18. SWAPPABLE COMPONENTS 18 Dremel and extruder attached to their respective adapter mounts.

19. SWAPPABLE COMPONENTS 19 Dremel and extruder mounted to the CNC/3D printer machine.

20. 3D PRINTING ELEMENT CONTROL 20 Temperature controls were meant to be controlled by the Raspberry Pi. That feature will have to be resumed at a later date.

21. RESULTS  The axis movement is working wonderfully. There is very little play in the mechanical movement.  The adapters for the CNC and 3D printer are easily interchangeable.  The CNC portion of the project works wonderfully (the software just has a bit of a learning curve.)  The 3D printer portion should be easy to configure into Mach3 and get it going once the correct pin header arrives. 21

23. CONCLUSIONS  These results are a step forward in the right direction to make this an extremely useful tool for myself and my peers.  Even though the 3D printer portion wasn’t entirely completed due to a minor issue, I now know that this is entirely possible to accomplish.  Nearly 200+ hours have been put into this project thus far and I intend to put many more to make it even better. 23

24. FUTURE WORK  Create an enclosure for the electronics that will mount to the machine.  Control the CNC/Dremel tool with Mach3 instead of being a standalone unit.  Adding the 3D printer heat bed along with onboard temperature control  Adding quick connect/disconnects for the motors so they can easily be replaced or removed.  The possibilities are ENDLESS! 24
