The $30 off Flashforge AD5X promo code at the top of this page is the lead offer and is best if you are buying the Flashforge AD5X multicolor 3D printer specifically. That code applies to the AD5X model only and gives a straight $30 reduction on that product while stock lasts. If you are buying other items, the sitewide threshold codes and filament deals below will often be a better match.
Big printer purchases (single high value printer or combined high spend): If your cart contains a single printer or reaches at least $900, use the $30 off orders over $900 code, because it applies to any purchase that meets the $900 minimum. For slightly lower large purchases, the $20 off over $600 code applies at $600 and the $10 off over $300 code applies at $300. Example: on a $950 order, the $30 off threshold code reduces your total from $950 to $920, saving $30.
Buying the Flashforge AD5X specifically: Use the $30 off Flashforge AD5X voucher above, since it targets that model. That code is the headline even if a percentage deal could save more on other items. If the AD5X is the main item in a bigger $900+ cart, compare the AD5X-specific $30 saving against the $30 off $900 code; both subtract $30 so either works, but use the AD5X code if the promotion restricts to that model.
Filament and accessories purchases: For filaments and accessories, the 20% off all filaments and accessories coupon or the site sale of 20% off all filament (no code needed) are usually the better choice. Example: on a $120 filament and accessory order, 20% off takes $24 off, leaving $96. That beats a flat $10 off over $300 when you are only buying supplies under those thresholds.
When you want multiple spools: The buy 2 filaments for 1 sale is best if you need two separate filament spools that are included in the promotion. For two $30 spools on that deal you pay $30 and save $30 compared with buying both at full price. That sale runs to November 1, 2026 and requires adding two eligible products to the cart.
Low spend or first time signup: If your cart is under $300 and contains no filament, sign up for the newsletter only if you want future promotions; it does not provide an immediate checkout discount. The small threshold codes begin at $300, so they do not help micro purchases.
When choosing between codes for the same basket, calculate the final total under each applicable offer and pick the lower total. Only one code or promotion can be applied at checkout unless the terms say otherwise, so compare the flat $10/$20/$30 options against the 20% filament deals on the items they cover and take whichever leaves you with the lower invoice.
