Can you promote in r/3dprintentrepreneurs?
A community about how to start and grow businesses using 3D Printing. 3D Print on Demand, Etsy, Shopify, Shows, Tiktok, Portals, and even how to sell Models.
The short answer
Be helpful and solution-focused first; if you mention your product or service, do so briefly and transparently and only when directly relevant to the question or discussion.
What works here
- sharing business tactics, launches, and case studies
- relevant tool or service mentions when they add value
- engaging constructively and answering questions
What gets posts removed
- purely promotional posts or blatant advertising
- off-topic posts about which printer to buy
- negative or non-constructive commentary
