Prototyping of portable medicine containers with embossed braille using an affordable desktop 3D printer

Abstract

Purpose

Prototyping with affordable 3D printers empowers small businesses to create prototypes within a day and carry out multiple iterations of design, size, shape or assembly based on analytical results, bringing better products to market faster. This paper aims to turn the ideas into proofs of concept, advance these concepts to realistic prototypes and investigate the quality of printed prototypes prior to large-scale production.

Design/methodology/approach

The experimental approach focuses on the prototyping of portable medicine containers by Fused Deposition Modeling (FDM), modifying the prototypes by adding auxiliary braille flags that indicate patient initials and dosing information, and performing the moisture permeation study as well as the stability study for model drug products (i.e. ibuprofen tablets, guaifenesin tablets, dextromethorphan HBr soft gel capsules).

Findings

The study shows that an affordable 3D printer helps to create functional and visual prototypes that give a realistic depiction of the design and offer physical objects that could be investigated for product quality and feasibility.

Originality/value

To the best of the authors’ knowledge, this study was the first attempt to use a desktop FDM-based 3D printer to prototype portable medicine containers in a blister packet appearance with auxiliary braille flags that help validate early concepts and facilitate the conversation on refining product features in a rapid and affordable manner.
