Common questions
I can't access STLSeller or STLAI after purchase. Check your email for purchase and account activation details. Each platform (STLFLIX, STLAI and STLSeller) may have a different password, so confirm registration was completed on all of them.
I'm a subscriber and the discount wasn't applied. Access the purchase through the official link https://platform.stlflix.com/live-bf26 and enter your subscriber email — the discount is applied automatically from there.
Where do I buy filament with the discount coupon? Filament purchases are made on Polymaker's own website, not on STLFLIX's store.
Is the printer included in the Lifetime purchase? No. The printer is the general giveaway prize; it isn't part of the Lifetime purchase.
I'm a subscriber of a different plan than Annual. Do I get a discount? Subscriber discount eligibility is checked automatically through the official link https://platform.stlflix.com/live-bf26, based on your registered email.
How do I cancel my Lifetime purchase? You can request cancellation from your account panel on the platform, or by contacting our support team. Refunds can be requested within 7 days of the purchase.
Is the Lifetime plan a 12-month subscription, or is it forever? It's a single purchase with permanent access. The amount can be paid in up to 12 installments, but once it's paid there's no recurring or monthly charge afterward.
