# SUNLU Standard Grey 3D Printer Resin, 4 kg

SUNLU Standard Grey 3D Printer Resin is a 4 kg UV-curing photopolymer resin for compatible LCD, DLP and SLA printers. Its claimed 365–405 nm wavelength range, low shrinkage and smooth, hard finish suit routine model printing and post-print colouring, while the bulk pack is best suited to buyers expecting regular use.

## At a glance

- Manufacturer claims low shrinkage for accurate part dimensions and shape.
- The listing describes a hard, smooth surface that is easy to colour after printing.
- The claimed 365–405 nm range covers LCD, DLP and SLA resin printers, subject to printer compatibility.
- The manufacturer says the resin can be cleaned with isopropyl alcohol or ethanol.

## Pros

- A 4 kg pack may suit frequent printing and reduce the need to replenish smaller quantities.
- Low shrinkage and a surface described as easy to colour are useful for dimension-conscious models and hand-finished prints.
- The listed 365–405 nm range supports use across multiple types of UV resin printer, where the printer's specifications match.

## Cons

- A 4 kg quantity is a substantial commitment for occasional users or those still choosing a resin.
- Cleaning is specified with alcohol solvents, so this is not presented as a water-washable resin.

## Before you buy

- The listing calls the pack 4 kg or 4000g, while the stated item and package weight is 4.6 kg. Treat 4 kg as the resin size and 4.6 kg as the listed packaged/item weight, not the resin quantity. Its 405 nm title wording is narrower than the feature's 365-405nm claim. Compatibility, low shrinkage, odour and finish are manufacturer claims, not independently verified results. Confirm the resin wavelength suits your printer.

## A good fit for

- Regular users of LCD, DLP or SLA resin printers whose equipment supports the stated wavelength range.
- Makers printing grey models that they plan to colour or finish after curing.
- Users who want a larger supply of standard photopolymer resin.

## Less suited to

- Occasional users unlikely to use a 4 kg pack.
- Buyers specifically seeking resin that can be washed with water.
- Anyone whose printer does not support the resin's specified curing wavelength.

## Customer feedback

The supplied evidence contains only a small aggregate rating sample, with all recorded ratings in the five-star category. That is encouraging but too limited to establish consistent print results or identify customer-reported strengths and drawbacks. No written customer feedback is provided, so buyers should weigh the listing's claimed finish and printer compatibility against their own printer requirements.

## Frequently asked questions

### Which printers is this resin intended for?
The listing names LCD, DLP and SLA printers and gives a 365-405nm printing wavelength. Check your printer's supported wavelength before purchasing.
### Is the pack 4 kg or 4.6 kg?
The listing describes the resin as 4 kg or 4000g, but gives 4.6 kg as the item weight and package weight. The figures refer to different stated quantities.
### How does the listing say to clean prints?
It names isopropyl alcohol or ethanol. It does not describe this resin as water-washable.
### What finish does the manufacturer claim?
The listing describes printed parts as hard and smooth, easy to colour, and claims low shrinkage. These are manufacturer claims rather than independently verified results.
