[Endorobotics x Creallo] Realizing Complex Medical Robot Simulator Parts with 3D Printing

Due to the curved structure and intricate geometry, injection molding and conventional machining were not feasible. Creallo’s 3D printing made it possible.

Pioneering Non-Invasive Endoscopic Robotics: About Endorobotics

Endorobotics is a high-tech company specializing in non-invasive medical robotics for gastrointestinal endoscopic surgery. Its vision is to lead the endoscopy field through technological innovation. The company’s flagship products include Robopera, a robotic assistant for endoscopic surgery, and EndoCubot, a surgical simulator designed for physician training.

These products are used in highly sensitive clinical environments where precision and repeatability are paramount, demanding exceptional design accuracy and functional integrity from the earliest development stages.

Why Endorobotics Chose Creallo: An Intuitive Online Manufacturing Experience

We could estimate lead time even before the final design was complete, which helped significantly with scheduling.

— Junhyuk Kim, R&D Engineer, Endorobotics

Endorobotics first learned about Creallo through a personal referral. With a strong focus on short lead times and high manufacturing quality, the team thoroughly reviewed Creallo’s portfolio, system capabilities, and pricing before deciding to move forward.

Creallo’s AI-powered online manufacturing platform bridges the gap between design and production through:

• Instant quoting and lead time estimation
• Detailed pricing including post-processing options
• Early-stage design file analysis and manufacturability feedback

These tools proved especially useful for the fast-paced development needs of medical device startups.

Creallo’s AI-based quoting system allows startups to make quick decisions by offering real-time estimates even during early design phases.

From Complex Curved Surfaces to Final Quality Control: Precision Delivered

The curved geometry was too complex for injection molding — 3D printing was the only viable solution.

— Junhyuk Kim, R&D Engineer, Endorobotics

The component produced by Creallo was used in EndoCubot, a simulator designed to mimic internal organs for surgical training. Its geometry included complex internal structures and organic curves that could not be fabricated with traditional machining or molding techniques. Fast iterations and tight timelines — hallmarks of medical robot development — added further challenges.

Creallo mitigated risks and ensured delivery through:

• Real-time simulations and quoting
• Pre-checks for surface quality and support mark impact
• Continuous manufacturability feedback
• Fast, centralized online communication and project support

Even during the preliminary design phase, the ability to gauge lead times helped Endorobotics manage schedules with greater confidence. Creallo’s consistent project management and responsive digital workflow also contributed to smooth collaboration.

Because this component was to be used in a tradeshow demo, surface finish and glossy paint quality were especially critical — and the results exceeded our expectations.

— Junhyuk Kim, R&D Engineer, Endorobotics

Utilizing high-precision 3D printing and a wide selection of materials, Creallo faithfully reproduced the original design with surface finishes and glossy coatings that rivaled injection molding standards. Endorobotics was highly satisfied with the product’s texture, color accuracy, and overall quality — all of which proved valuable in both training and demonstration environments.

Endorobotics specifically requested precise part alignment and premium paint finishes. We worked closely with our production team to simulate assembly before delivery, ensuring the coating didn’t affect fit. This enabled us to deliver a final product ready for immediate use.

What’s Next: Scaling with Creallo’s Manufacturing Capabilities

Following the success of the first collaboration, Endorobotics has continued working with Creallo on further components. They are also exploring vacuum casting for low-volume production — a process known for cost-efficiency, surface quality, and design fidelity.

As a trusted precision manufacturing partner for medical robotics, CREALLO looks forward to deepening its collaboration with Endorobotics in the years ahead.

We’ve already requested additional components for upcoming projects and are considering vacuum casting in addition to 3D printing.

— Junhyuk Kim, R&D Engineer, Endorobotics

Vacuum casting strikes a balance between cost, surface finish, material variety, and accuracy — making it ideal for Endorobotics’ high-quality, small-batch needs.
