SUCCESS STORY / SMALL-BATCH RESIN PRINTING
Tiny part.
Serious geometry.
A custom wire holder small enough to sit on a coin. A batch big enough to move an idea into the customer's workflow.
THE CHALLENGE
The small component
that still has a job to do.
The brief was a tiny holder for very fine wire used in a device assembly and its gluing operation. Small overall size did not mean simple geometry: the supplied photographs show a slender body with narrow slots and repeated features packed into very little space.
For a custom component like this, the useful question is how to turn the required shape into a practical batch. TECHNAST produced the clear parts using resin 3D printing, bringing the detail of the individual component together with the repeatability of a digital manufacturing workflow.

THE PROCESS CHOICE
Why resin fits
work at this scale.
Resin printing builds parts by selectively curing a liquid photopolymer. It can reproduce fine features and complex shapes directly from a digital model, making it useful for custom components and modest production runs that do not justify dedicated mould tooling.
The process choice is only the start. Small features demand attention throughout preparation and finishing. Orientation influences printability and surface finish; supports need to be considered around functional surfaces. Washing must remove residual resin from openings, and curing must follow the selected material's requirements.
The right resin depends on the application: adhesive compatibility, heat, chemicals, loading and handling all matter. A fine-looking print is the starting point for checking the part against its actual job.

A small part.
A whole batch.
Real photographs of the completed parts make the outcome tangible: the same compact geometry, repeated across the production batch.
THE PROJECT OUTCOME
For this project, TECHNAST reports that the parts were produced in three days, providing approximately a year’s supply at the customer’s expected usage. A difficult little component had become a batch on hand, ready for the customer’s assembly workflow.
Turnaround and supply coverage refer to this order. Supply coverage describes expected consumption, not tested part lifespan; future lead times depend on the project.
