1. Product developers served; average revenue per developer
The two most crucial elements for Proto Labs' earnings are the number of product developers it serves in a given quarter and spending per developer. Ideally, investors will want to see both of these figures rising on an annual basis as it indicates that not only is acceptance for its rapid manufacturing and 3D printing services growing in the marketplace, but also that existing developers becoming more loyal to Proto Labs' manufacturing services platform.

For perspective, Proto Labs served 12,414 product developers in the fourth quarter, 21% more than the year before, and revenue per product developer increased by 8.4% to $5,942.

2. International growth
Although it's been a challenging environment for many industrial-facing companies to drive meaningful growth internationally, Proto Labs has been a notable exception.

Even after accounting for unfavorable currency translations due to the strong U.S. dollar, Proto Labs' first-quarter revenue in Japan rose 54% year over year, while it increased 22% in Europe.

3. Operating profit margin
