Build logsA build log must include the machine model, material used, and at least one photo or a clear description of the result. Posts without these details may be moved to the "Questions" board.

Tool reviewsReviews should focus on your own experience with calibration, maintenance, and real output quality. We do not accept sponsored posts or affiliate-driven recommendations. If you received the tool for free, say so at the top.

Marketplace threadsUsed equipment listings must state the exact model, age, and asking price in the first post. No auction-style bidding. Meetups are arranged in person; the forum only helps coordinate time and place.

Expert Q&A sessionsModerated sessions run every other Saturday. Questions are collected in advance, and answers are posted as a summary thread. Off-topic comments during a live session will be removed.

Local meetupsMeetup organizers must confirm the venue and date before posting. If an event is cancelled, the thread is locked and a notice is added. We do not handle payments or registrations.

Content boundariesDiscussions about filament, wood, acrylic, and metal are welcome. We do not cover topics related to trading, betting, or any form of financial speculation. Keep the focus on making and fixing.
