- The leader of the Application Engineering team at Xometry
- Xometry is an online instant quoting platform for custom manufacturing projects, which utilize a professional network of thousands of manufacturers
- Greg’s team handles special case projects that require attention to material selection, design-for-manufacturing, and technical engineering resources
- Plays a vital role in vetting new technologies and materials to add to Xometry’s manufacturing portfolio
- Background is in product development using rapid prototyping, focusing on the various applications of industrial 3D printing and advanced manufacturing
Digital Manufacturing
- Uploading and interpreting customer’s files
- Can uploading to the cloud replace drawings?
- Drawings contain so much information that is necessary
- Is it too easy to just dump in a 3d model and not worry about the rest?
- Experienced vs Newbie customers – What kind of resources exist for both?
- Assemblies
- Tolerances and Stackup
Breaking tradition
- How is “digital manufacturing” replacing the more traditional customer/manufacturer relationships?
- Approvals and certifications?
- Inspections and reports?
- If a customer wishes to do a walk through or receive specific factory information is that available?
The Network of Partners
- How to handle capability?
- Quality?
- Lead times?

About the Hosts

Parker Dillmann
Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.
In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.
In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.
Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.

Stephen Kraig
Stephen Kraig began his electronics career by building musical oriented circuits in 2003. Stephen is an avid guitar player and, in his down time, manufactures audio electronics including guitar amplifiers, pedals, and pro audio gear. Stephen graduated with a BS in Electrical Engineering from Texas A&M University.
