Elegoo Labor Day Deals: Neptune 3 Pro for $169, Neptune 4 Plus for $309

Elegoo has slashed prices on two of its most popular 3D printers for Labor Day, and the deals are genuinely hard to ignore. The Neptune 3 Pro is down to $169, while the Neptune 4 Plus sits at $309. That is up to 35% off both machines, and the discounts expire in less than a day.

Neptune 3 Pro: A Starter Workhorse

The Neptune 3 Pro remains one of the best entry-level printers on the market. It has a direct drive extruder that handles TPU, PETG, and PLA without much fuss. Auto bed leveling and a heated flex PEI platform remove most of the hassle from first prints. Assembly takes under an hour and uses just seven screws, so you can go from unboxing to printing in a single afternoon.

Build volume is 225 x 225 x 280 mm, which is enough for most hobby projects. The quiet operation is a nice touch if you share a house with light sleepers. At $169, this is priced well below what major retailers usually charge for comparable machines.

Neptune 4 Plus: Big Prints, Big Value

If your projects run large, the Neptune 4 Plus is the better pick. Its 320 x 320 x 385 mm build volume lets you print cosplay armor, large props, or full-scale prototypes without splitting parts. The dual-gear direct drive extruder and the same oversized part cooling fan found on the Pro keep speeds high and surface finish clean.

This model also adds acceleration sensors, integrated Wi-Fi, and open-source firmware support. Those extras make it easier to tune and troubleshoot as you get deeper into the hobby. The $309 price is aggressive for a printer this size.

Which One Should You Grab?

Start with the Neptune 3 Pro if you are new to 3D printing and want something reliable that is easy to set up. Move to the Neptune 4 Plus if you already know you need a larger build area or plan to push the printer with faster speeds and bigger projects.

Both deals end quickly, so if you want either printer at these prices, you should decide soon.
