Prototypes need to meet well-defined product requirements. To avoid production delays, engineers want prototypes that are as close as possible to production quality. The final components must also meet requirements for rapid production to support faster manufacturing and efficient assembly.

The Limitations of Micro Injection Molding

Traditionally, manufacturers have relied on micro injection molding to produce electronic components. However, molding requires tooling which can be expensive and has long turn around times. As a result, molding can lead to extended project budgets and timelines. For example, tooling can take as long as 10 – 12 weeks to produce. If there are any design changes, tooling may then need to be discarded and new tooling needs to be ordered and paid for.

The Advantages of Prototyping Electronic Components

3D printing eliminates the need for tooling, reducing the time and cost between design iterations and test cycles. However, it is important to choose the right 3D printing technology to avoid tradeoffs between production speed, part precision, and surface quality. Micro DLP technology can rapidly print small electronic components with the required precision. Using Micro DLP technology to prototype electronic components matches the resolution, size, and tolerance of parts produced through injection molding.

Micro DLP technology relies on photopolymer resins with reliable thermal and mechanical properties. Electronic components prototyped with these resins are stable when exposed to high temperatures. With the resin’s thermal and mechanical properties, Micro DLP-printed electronic components can connect reliably and support efficient assembly.

Additive Manufacturing’s Support for Miniaturization

With the right additive manufacturing process, electronics designers can achieve the precision of micro injection molding without high cost and long timelines. Micro DLP technology provides the precision and resolution needed as electronic components become smaller.
