3D Printing Technician

About RhythmRx.ai:

RhythmRx Pvt Ltd is a fast-growing MedTech startup developing next-generation healthcare and acute care solutions. We are seeking a 3D Printing Technician (Prototyping Engineer) who can bridge the gap between design and fabrication. This role combines CAD modeling, design optimization, and digital fabrication with hands-on 3D printing operations, maintenance, and quality control.

Role Overview:

As a 3D Printing Technician (Prototyping Engineer), you will own the end-to-end prototyping workflow — from creating and optimizing 3D models, to preparing slicing files, to operating and maintaining 3D printers, to delivering high-quality prototypes and production-ready parts. You will play a key role in supporting R&D;, engineering, and production teams in bringing innovative medical device concepts to life.

Key Responsibilities:

• Create and modify 3D models using CAD software (e.g., SolidWorks, Fusion 360)

• Apply Design for Additive Manufacturing (DfAM) principles

• Set up, calibrate, and operate FDM, SLA, and SLS printers, including Bambu Lab Carbon

• Manage slicing workflows using Cura, PrusaSlicer, Simplify3D, and Bambu Studio

• Handle material preparation, storage, and selection (PLA, ABS, PETG, resins, powders)

• Conduct post-processing (support removal, sanding, smoothing, priming, painting)

• Perform maintenance and troubleshooting of 3D printers • Inspect prints for tolerances, accuracy, and surface finish

• Maintain records of print jobs, materials, and maintenance logs

• Collaborate with R&D; and engineering teams for rapid prototyping cycles

Required Qualifications:

• Bachelor's degree in Mechanical, Electrical, Production, or related engineering field

• Proficiency in CAD software (SolidWorks, Fusion 360 preferred)

• Experience with slicing and preparing 3D models for printing

• Hands-on experience with FDM/SLA/SLS printers (including Bambu Lab series)

• Knowledge of tolerances, mechanical systems, and DfAM principles

• Strong troubleshooting and problem-solving skills

• Attention to detail, teamwork, and adaptability

Preferred Qualifications

• Prior experience in additive manufacturing or prototyping labs

• Familiarity with post-processing techniques and finishing workflows

• Knowledge of medical device prototyping standards (a plus)

• Exposure to multiple printing materials and their properties

Why Join Us

• Hybrid role: Work across CAD design and hands-on 3D printing

• Be part of a cutting-edge MedTech startup shaping the future of healthcare

• Opportunity to influence the entire prototyping lifecycle

• Collaborative, innovation-driven work environment
