Materials Chemist Intern

Company Overview

\n

3D Architech is pioneering next-generation metal manufacturing infrastructures that push the boundaries of design at an unprecedented scale – at 10 micron and lower. Our proprietary, gel‑enabled metal manufacturing platform enables geometries, thermal performance, and materials combinations that are not achievable with conventional additive or subtractive processes. Our operation spans the USA, Japan, and Taiwan, bridging advanced materials R&D with scalable manufacturing for thermal management applications. As we expand our R&D operations in the US, we’re seeking talented engineers to drive our manufacturing technology and the development of application-specific products for cooling devices.

Job Summary: Materials Chemist Intern

\n

3D Architech is an early-stage deep-tech startup developing a proprietary gel-enabled metal manufacturing platform. In this internship, you will contribute to gel innovation—the most fundamental and upstream part of our manufacturing process—through hands-on work spanning polymer gel formulation, resin development, gel preparation, 3D printing, and materials characterization.

\n

You will work on technically deep and sometimes academic or fundamental challenges while learning to identify the shortest practical path to real-world impact. The goal is to develop a startup mindset that connects rigorous scientific reasoning with rapid experimentation, manufacturability, and the ability to scale successful materials and processes toward mass production as quickly as possible.

\n

\n

Working with the polymer gel R&D team, you will translate technical questions into well-designed experiments, generate and interpret data, and use the results to improve gel materials and the processes that connect resin preparation, printing, post-processing, and final product performance.

\n

This role is suited to someone who wants to combine wet-lab materials research with fast, business-driven development in an evolving startup environment.

Responsibilities:

\n

• \n
• Plan and execute wet-lab experiments safely, attentively, and with clear technical objectives.
• \n
• Prepare and evaluate polymer gels and photopolymerizable resins, including formulation, mixing, casting, washing, and related processing steps.
• \n
• Support gel-based 3D printing experiments and investigate relationships among resin composition, printing conditions, gel quality, and downstream manufacturing performance.
• \n
• Characterize gel, resin, and printed-material properties using appropriate mechanical, transport, thermal, imaging, or processing-based methods.
• \n
• Accurately document experimental procedures and data, analyze results critically, and communicate conclusions, uncertainties, and recommended next steps.
• \n
• Iterate quickly in response to new findings, identify practical improvements, and balance fundamental investigation with the shortest path to a scalable solution.
• \n
• Take ownership of assigned work, maintain reproducibility and data integrity, and deliver useful results on startup-relevant timelines.
