Buy the one accessory that fixes your workflow.

You do not need a drawer full of upgrades. Start with the material, drying or resin post-processing tool that matches the kind of printing you actually do.

For most FDM printers

eSUN PLA+

A sensible first spool for learning, calibration prints and everyday models. Start with one reliable color before buying a whole shelf of filament.

See eSUN PLA+ on Amazon

For moisture-sensitive filament

SUNLU S2 dryer

Useful when PETG, ABS, nylon or long prints become inconsistent because the filament has absorbed moisture. It is not required for every PLA spool.

See SUNLU S2 on Amazon

For Mars and Saturn resin users

ELEGOO Mercury XS

A dedicated wash-and-cure setup makes resin post-processing more repeatable. Choose it only if you are ready for gloves, ventilation and responsible resin handling.

See Mercury XS on Amazon

For resin printers only

ELEGOO ABS-Like 3.0+

A general-purpose resin option when you want a less brittle result than basic standard resin. Follow the product safety information and local disposal rules.

Before buying a replacement

Compatibility comes before the discount.

For hotends and nozzles

Match the exact printer model.
Check nozzle diameter and material.
Confirm connector, voltage and mounting style.
Do not treat a generic “0.4 mm nozzle” as universal.

For resin equipment

Match the printer’s build area and workflow.
Use gloves, eye protection and ventilation.
Never pour uncured resin or contaminated wash water down a drain.
Follow the resin safety data sheet and local disposal rules.
