3D Printing

A stylish Sci-Fi inspired case for your Meshtastic radio

Design engineer for several subsystems on HSE 240, a next generation high temperature industrial Fused Filament Fabrication 3D printer. Subsystems include dry filament storage, nozzle purging and cleaning, electrical systems cooling, frame & structure, cosmetic skins.

Was lead mechanical engineer for continuous improvement projects on HSE 180 and HSE 280 industrial 3D printers, including development of new hotends, nozzle cleaning and purge system, filament feed system, and safety improvements.

Here are all the standard procedures for unclogging nozzles, in order of difficulty/invasiveness.

Project lead for the Pulse E-Series, the 5th major iteration of the product line. Successfully launched in September 2020. Scheduled tasks and planned milestones. Coordinated research & development effort, testing, and training production staff.

PID is the control algorithm the printers use for holding temperature. The parameters for this algorithm control how fast the printer reaches the set temperature, and how well it holds that temperature once it gets there. Fortunately, the printer has an automatic way of tuning these values.

Developed filament flow sensor addon for 3D printers allowing for closed loop control of extrusion. Minimized part count by using a compliant mechanism. Maximized reliability and lifespan by using solid state hall effect sensor. Wrote I2C interface drivers for 3D printer firmwares Marlin (Arduino architecture) and Smoothieware (ARM architecture). CAD in Onshape, schematic and PCB layout in KiCAD.

The internet’s favorite hobbyist-level 3D printer comes to MatterHackers.

A plugin to show previews of STL files (3D printing models) in your file manager. Works on Linux and Windows. Written in Rust, using OpenGL.

Converting your cosplay from Pepakura to 3D printable models

Developed 3D printer addon allowing wireless connectivity, based on ESP8266 MCU. Did component sourcing, PCB design in KiCAD, case design in Solidworks, and wrote user facing documentation.

MatterHackers pros take an in-depth look at why this incredibly precise resin 3D printer is quickly becoming a crowd favorite.

MatterHackers’ in-house 3D Printer Technician, Mike Campos, is using 3D printing to develop an affordable prosthetic hand that can be controlled by muscle sensors.

There are a lot of reasons a printer could have trouble getting to or staying at the right temperature. Here is a breakdown of the possible scenarios and their solutions.

MatterHackers pros take an in-depth look at this fast-processing, 32-bit controller board that will help produce cleaner 3D printed parts.

Our engineers examine why the Ultimaker 3 is the perfect machine for print-to-production parts.

Contributed to development of the MatterControl T7X, a tablet-like 3D printer control device powered by Android. Did mechanical design of the body for injection molding. Automated flashing of Android ROM. Design of I/O breakout board in KiCAD.
