Is r/3dprinter growing?

How active is r/3dprinter?
We don't have a reliable posting-rate sample for r/3dprinter yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the crawl accumulates more.
Can I promote my product in r/3dprinter?
We don't have a promo-tolerance read for r/3dprinter yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
