| Sydney has become one of the strongest fintech and hardware startup hubs in the world, but physical products still need to be prototyped before they can be pitched, tested, or sold. This guide explains how founders building payment devices and consumer hardware actually use 3D printing, from rough FDM concept models in the early days through to investor ready SLA parts and production ready designs at Series A. It covers material choice for products that get handled every day, what fintech hardware needs to consider around EMV and PCI DSS expectations, how to protect a design before it is patented, honest cost numbers across FDM, SLA, SLS, and injection molding, and when to move from prototype to full production. |
