This work introduces dissolvable supports to single- and multi-material metals AM. The multi-material approach uses material choice to design a functionally graded material where corrosion is the functionality being varied. The single-material approach is the primary focus of this thesis, leveraging already common post-print heat treatments to locally alter the microstructure near the surface. By including a sensitizing agent in the ageing heat treatment, carbon is diffused into the part decreasing the corrosion resistance to a depth equal to at least half the support thickness. In a properly chosen electrolyte, this layer is easily chemically, or electrochemically removed. Stainless steel 316 (SS316) and Inconel 718 are both investigated to study this process using two popular alloys. The microstructure evolution and corrosion properties are investigated for both. For SS316, the effect of applied electrochemical potential is investigated to describe the varying corrosion phenomena induced, and the effect of potential choice on resultant roughness. In summary, a new approach to remove supports from metal AM parts is introduced to decrease costs and further the field of metals AM by expanding the design space.
Ctrl+P is an online store for 3D printed items, founded by four members with experience in computer-aided design (CAD) and financial management. They initially started with a broader scope but later focused on designing custom pool racks for the pool community. They conducted customer discovery with over 634 ASU students and landed an ongoing business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team has already made a profit and aims to be revenue-earning by the end of the project. The financial plan includes potential expenses for website development, printer filament, and 3D printers. Ctrl+P's brand mission is to print products desired by customers that consult Ctrl+P. The long-term goal of the team is to continue to gain customers and expand the business to a larger customer base.
This thesis paper outlines the Ctrl+P print store business, an honors thesis project conducted through the Founder’s Lab program at Arizona State University. The project is an online store for 3D printed items, operated by a team of four students with backgrounds in engineering and finance. Three team members have experience in computer-aided design (CAD) and can design products to print and sell, while the fourth member is responsible for the financial side of the business. The project began with a broader scope but later focused on the niche community of pool. In the spring semester, the team conducted customer discovery with over 600 ASU students; and in the fall semester, reached out to several pool halls to facilitate feedback on designs of custom pool racks. The team currently has a pending business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team's goal was to be revenue-earning by the end of the project, and they have already made a profit as a business.
Ctrl+P is a start-up business created through the founder's lab class at W.P. Carey. Our group created a 3D print shop that specializes in making products, such as customizable key chains and prominent landmarks, as well as custom 3D printed solutions for local businesses and companies.
