SUNLU Special Offer Discount Code "KANNY" Get 10% Off on Your Purchase

If you're shopping for 3D-printing filament, resin, dryers, or accessories, SUNLU is a brand worth considering. Its official store carries PLA, PLA+, PETG, TPU, ABS, specialty and engineering filaments, UV resins, filament dryers, and other 3D-printing equipment.

The promotional code featured in this article is KANNY, which is being advertised online as a 10% discount on eligible SUNLU purchases. Recent third-party listings specifically promote KANNY as a 10% SUNLU discount.

I could not independently confirm KANNY on SUNLU's official promotions page. SUNLU's currently published official promotion lists a different 5% code for qualifying in-stock filaments and resins, with a $50 minimum purchase and a one-use-per-customer restriction. So, as with any third-party promotional code, verify the actual discount shown at checkout before completing your purchase.

What Is SUNLU?

SUNLU specializes in 3D-printing consumables and related equipment. Its product lineup is broad enough to cover many stages of a typical 3D-printing workflow, from basic PLA filament to specialized materials and filament-drying equipment.

Its main categories include:

PLA and PLA+ filament
PETG filament
TPU flexible filament
ABS filament
Specialty and engineering materials
UV resin
Filament dryers
3D-printing accessories

For beginners, this variety makes it relatively easy to start with standard PLA and expand into different materials as printing requirements become more demanding.

Why Consider SUNLU?
Broad Filament Selection

SUNLU offers a substantial range of filament types and colors. Its official store currently has dedicated collections for PLA, PLA+, PETG, ABS, TPU, engineering filaments, specialty materials, and more.

PLA is generally a convenient starting point for beginners, while PETG can be useful for projects requiring different mechanical characteristics. TPU provides flexibility, while engineering materials target more demanding applications.

The important point is to choose the material according to your printer and project rather than simply choosing the cheapest spool.

Resin for Detailed Prints

SUNLU also sells UV resin for compatible resin 3D printers.

Resin printing can be particularly useful for miniatures, detailed models, prototypes, and projects where fine surface detail matters.

Different resin formulations have different characteristics, so printer compatibility, exposure settings, curing requirements, and intended use should always be considered.

Filament Dryers

Moisture is a common concern with 3D-printing filament.

SUNLU offers dedicated filament dryers designed to help users manage moisture before and during printing. Its store currently lists several dryer models and related collections.

For someone who prints frequently or works with moisture-sensitive materials, proper filament storage and drying can make a noticeable difference in print consistency.

Regular Deals

SUNLU frequently runs product promotions rather than relying solely on coupon codes.

Its current store features collections such as daily hot deals, summer flash deals, membership sales, engineering-filament flash sales, and bundle offers.

That means it's worth comparing the regular sale price with any promotional code before ordering.

How to Use the KANNY Discount Code

If you want to test the advertised promotion, add your desired SUNLU products to your cart and proceed to checkout.

Enter KANNY into the available discount-code field and apply it.

Before paying, review the complete order summary. Check:

Whether the code was accepted.
Whether the advertised discount appears.
Which products qualified.
Whether shipping charges have changed the final price.
Whether another promotion is already providing a larger saving.
The final amount you'll actually pay.

This final checkout amount is the most reliable confirmation that the promotion applies to your particular order.

SUNLU's Official Discount Options

SUNLU currently publishes its own promotional information.

Its official promotion page lists code 5OFFSLWIKI, offering 5% off qualifying in-stock filaments and resins with a $50 minimum purchase. The official terms also state that it can only be used once per customer and cannot be combined with other discounts.

The official store is also currently displaying SALE50 as a promotional code on its storefront.

This is why I wouldn't automatically assume that a 10% coupon is the best possible deal. Compare the final prices produced by the available offers.
