3D Printer Project

Objective

​

For the final project in my Mechanical Engineering Design course, we developed an advanced conceptual design for a 3D printer used in a small shop or office setting.

Project Description

​

To begin the project, my team conducted extensive research on the 3D printing market and analyzed the benefits of the current printer types. A set of Engineering Specifications was then established. With further consideration, we decided to focus on the SLA printer because of its high quality, resolution, and accuracy. A CAD model for visual presentation of the design was created as well as a detailed justification report. 

​

Design Description

​

A lead screw was chosen as the linear motion support for the print bed, allowing it to travel up and down during the printing process. Two smooth rods are also attached to the print bed to prevent axial movement. The print bed is constructed out of glass so the resin can be securely cured onto the build plate but the finished product can also be easily removed. Closed lubricated pillow-block mount bearings are used as support for rotational motion between the motors and motor shafts. This allows the bearings to be replaced easily, thus meeting the design objective of ease of maintenance. The overall design is made out of mostly stainless steel due to its corrosion resistance, low maintenance, long life cycle, and high strength.

My Role

​

In the team, my role was to help create parts of the SLA printer on Solidworks. As well, I contributed with research, cost calculation, and design justification. Working with a group allowed me to practice my organizational, time management, and communication skills, as I needed to complete my tasks on time and relay information back to others.
