Application of the week: Custom cases for electronic devices

Welcome back to our application spotlight series, where we explore real-world 3D printed parts that help industries move smarter, safer, and more efficiently. Each week, we highlight practical use cases that demonstrate the power of additive manufacturing to solve hands-on challenges.

This week, we’re featuring a custom 3D printed protective case designed to keep essential electronics safe in demanding warehouse environments, specifically at busy airport logistics hubs.

Protecting critical tech with flexible 3D printing

In airport warehouses, mobile devices are key tools for tracking inventory and managing daily operations. But frequent handling, fast-paced workflows, and hard concrete floors make accidental drops a constant risk.

To protect these devices, IMES3D developed custom bumpers using soft TPU, a flexible and impact-absorbing material. Designed specifically for each device’s dimensions, these bumpers provide a secure fit that cushions against damage without interfering with functionality.

Why soft TPU and 3D printing were the right solution

Soft TPU is ideal for protective applications thanks to its flexibility and durability. By using UltiMaker’s Factor 4, IMES3D was able to print the bumpers quickly and with precision, ensuring a snug fit around complex device geometries.

Here’s what makes this application stand out:

Impact-resistant and durable TPU’s rubber-like properties allow it to flex and absorb shocks, protecting delicate electronics even after repeated drops.

Custom-fit for every device Each case is tailored to the size and shape of specific devices used on-site—something that would be costly and time-consuming using traditional manufacturing methods.

Efficient, on-demand production No need for large inventories or waiting on external suppliers. Cases can be printed in-house as new devices are added to the fleet or existing ones are updated.

Optimized for rugged environments Whether it’s a handheld scanner or industrial tablet, these bumpers are designed to hold up in the high-pressure conditions of airport operations.

Designed for protection. Built for performance.

When durability, customization, and speed matter, 3D printing offers a practical advantage. With the UltiMaker Factor 4 and flexible filaments like TPU, manufacturers like IMES3D are delivering tailored protection for essential technology - ensuring that tools stay online, even when things hit the ground.
