Internship 3D Printer Operator information

What does an internship 3D printer operator do?

An Internship 3D Printer Operator assists with the setup, operation, and maintenance of 3D printing machines under supervision. They help prepare print files, load materials, monitor prints, and troubleshoot common issues. Interns also may be involved in post-processing tasks like cleaning or finishing printed parts and documenting the process. The role provides hands-on experience and learning opportunities in additive manufacturing technologies.

What types of projects and responsibilities can an internship 3D printer operator expect to handle during their placement?

As an Internship 3D Printer Operator, you can expect to assist with preparing 3D models for printing, operating and maintaining various types of 3D printers, and ensuring print quality through post-processing tasks such as cleaning and finishing parts. You'll likely support the engineering or design teams by troubleshooting print issues, managing print queues, and documenting results. This hands-on role provides exposure to a range of materials and technologies, offering valuable experience in a collaborative, project-driven environment.

What are the key skills and qualifications needed to thrive as an internship 3D printer operator, and why are they important?

To thrive as an Internship 3D Printer Operator, you need a basic understanding of 3D printing processes, materials, and safety protocols, often supported by relevant coursework or hands-on experience. Familiarity with 3D modeling software (such as Blender or SolidWorks), slicing software, and specific printer hardware is typically required. Attention to detail, problem-solving abilities, and strong communication skills help interns manage tasks and troubleshoot issues effectively. These skills ensure quality output, safe operations, and efficient teamwork in a technical environment.

What is the difference between Internship 3D Printer Operator vs 3D Printing Technician?

AspectInternship 3D Printer Operator3D Printing Technician
CredentialsTypically pursuing or recent graduate, no formal certification requiredRelevant certifications or technical training often preferred
Work EnvironmentEntry-level, supervised environment, often in educational or startup settingsMore specialized, may work in manufacturing or industrial settings
ResponsibilitiesAssisting with 3D printer setup, basic operation, and maintenanceOperating, troubleshooting, and maintaining 3D printers independently

The Internship 3D Printer Operator role is an entry-level position focused on learning and assisting with 3D printing tasks, often as part of an internship program. In contrast, a 3D Printing Technician has more hands-on responsibilities, requiring technical skills and experience to operate and maintain 3D printers independently. Both roles are common in industries utilizing 3D printing technology, but the technician position typically demands more expertise and certification.

Senior Mechanical Design Engineer

NanoCore Technologies

San Francisco, CA • On-site

$105K - $145K/yr

Full-time

Job description

Company Description
NanoCore Technologies is an early stage technology company developing a method of metal additive manufacturing an order of magnitude less complicated and less expensive than existing printers. Today, popular metal 3D printers cost half a million dollars or more and use complicated high-powered lasers and controlled atmospheres. NanoCore is taking an entirely different approach that utilizes proprietary materials science and machine design to make metal 3D printing easier, simpler and less expensive than previously imaginable. To put it simply, we believe our technology will fundamentally change how metal parts are made.
We are a dedicated team of engineers and scientists passionate about manufacturing innovation. We see technical challenges as opportunities, and through focus and teamwork we find creative solutions. Apply only if you are excited about getting your hands dirty. NanoCore is located in San Francisco, CA and is walking distance to BART & Caltrain and offers competitive salaries, benefits and stock options.
Job Description
You will combine experience in machine design with a solid mechanical engineering and analysis background to help NanoCore bring its first metal 3D printer to market. Under the supervision of the VP of Engineering, you will be responsible for leading major subsystems of a precision machine through the full design process--from definition to part design, planning and testing. You will produce electro-mechanical components within a high precision machine that must withstand the rigors of constant industrial usage. Tasks include:
  • Design and analysis of parts and electro-mechanical assemblies which will be integrated into motion controlled stages, including BOM, revision control, and sourcing.
  • Rapid prototyping to realize designs, plus experiment and fixture design to confirm part and subsystem operation using industry standard metrology tools.
  • Maintaining and advancing on-site machine tools and mechanical equipment, as applicable to NanoCore's metal printing process.
  • Presenting concepts, managing workflow, documenting progress, cooperating and contributing as part of the larger engineering team of mechanical, electrical, materials and software engineers.

Qualifications
• Demonstrated expertise in design of precision industrial and/or scientific equipment, deploying sensors and actuators to support a multidisciplinary design process.
• Proven history for "getting things done" and track record for moving products from design into full scale manufacturing, with 4-6 years minimum work experience as an ME in machine design.
• Demonstrated ability to solve a wide range of technical problems with creativity, where analysis of situations or data requires an evaluation of a variety of factors. Matlab/Python or EE skills a plus.
• Experience setting up, operating, and/or maintaining mills, lathes, CNC tools, and motion control systems. History of working hands-on with electrical, thermal, and/or airflow systems a plus.
• Bachelors or Masters in mechanical engineering or related field. Strong verbal and written communication skills, as demonstrated through interactions with peers across their organization.
Additional Information
All your information will be kept confidential according to EEO guidelines.
