Amolen is a filament manufacturer, not a printer brand. If you already own a 3D printer, Amolen is one of the companies that supplies the plastic it eats. Everything is sold through a conventional online storefront at amolen.com, and the catalogue is organised by material and finish rather than by printer model.
The main categories are PLA Silk, PLA, Flexible, PETG, PLA Matte, Variety Packs and Accessories. Amolen leans towards specialty lines — Silk, Spiral, Multicolor, Shiny and Matte — rather than plain single-colour spools alone.
If you are new to this, the three material families on offer break down roughly as follows:
PLA is the standard starting material and the bulk of Amolen's range. The company states its standard PLA formula supports printing speeds up to 600 mm/s while holding dimensional accuracy and layer adhesion.
PETG sits alongside PLA as a separate catalogue category.
TPU, listed under Flexible, is the soft, rubbery option.
Finishes are a separate consideration from material. Silk and Shiny give a reflective surface, Matte removes the sheen, and Multicolor and Spiral shift colour along the length of the filament. Amolen also sells glow-in-the-dark filament: each glow spool contains 20% glow powder, and roughly 30 minutes under strong sunlight or UV light will charge it. There is a Glow variety pack of four 200 g spools in different colours, and a rainbow glow option that changes colour every 5 m.
One practical detail worth knowing before your first order: spools ship vacuum-sealed, because PLA absorbs moisture from the air. Keep that seal intact until you are ready to print.
Once you have chosen spools, the saving comes in at checkout. The code is GLOWUP, and it applies a 5% discount to your cart subtotal.
Despite the name, GLOWUP is not restricted to glow-in-the-dark filament. It works against the subtotal, so it covers whatever mix of PLA, PETG, Flexible or variety packs you have added.
The 5% is calculated on the subtotal before shipping and tax are added. That means the figure you see deducted will be based on the goods total, not the final amount charged to your card.
Open amolen.com and add your spools to the cart.
Go to the cart and proceed to checkout.
Find the discount code or gift card field near the order summary. On a phone, tap the 'show order summary' toggle first, otherwise the field is hidden.
Type GLOWUP in capitals, with no leading or trailing spaces. Copy-paste often drags a space along with it, so check before applying.
Apply the code and confirm that a discount line appears and reduces the subtotal by 5% before you pay.
If no discount line appears, the code has not been accepted, regardless of what the field looks like.
Amolen runs a Deals area covering multi-roll and bundle pricing, plus quantity offers advertised by the store: $6 off three spools, $18 off six, and $40 off ten. Whether GLOWUP can be combined with these depends on how they are implemented. If the quantity discounts are built into the listing prices, GLOWUP should still apply on top. If they are delivered as codes themselves, they will likely conflict, since storefronts of this type normally permit only one discount code per order. The cart page is the place to test this before committing.
Amolen also operates a loyalty and incentive programme that lets customers earn rewards on filament purchases, and it has at times offered free domestic US shipping as a limited-time promotion. Neither is guaranteed at any given moment.
Shipping costs, promotional periods and regional availability vary by country, so check the current shipping terms for your own address on the cart page rather than assuming. The single reliable test for the code is the discount line in the order summary: if the subtotal drops by 5%, GLOWUP has worked.
