Tech Breakdown: Peopoly’s Moai SLA 3D Printer

The Peopoly Moai (Moh-eye) is a straightforward SLA printer which you’ll be able to construct your self in as little as 6 hours. The package prices beneath $1,300 and will get extremely detailed prints. Right here we’re going to try why the Moai is an superior resin printer that will not break the financial institution, and why it must be added to your 3D printing office.

What’s SLA?

SLA stands for Stereolithography, which is a very totally different course of from the Fused Filament Fabrication (FFF) printers you might be in all probability used to.

In contrast to FFF printers, which soften plastic and spit it out, SLA printers use a laser to harden gentle delicate resin. The resin is saved in a tank with a clear backside. Beneath is the laser, which shoots up into the tank. The article is printed the wrong way up, hanging from a platform which rises up out of the tank.


The benefit of SLA is the unbelievable element it might probably obtain. The extremely targeted laser on the Moai permits it to print particulars as small as 0.067 mm. That is an order of magnitude higher than the 0.400 mm nozzles customary on most FFF printers. The Moai also can print layers all the way down to 0.015 mm thick, which is one quarter the beneficial minimal on most FFF machines.

The Moai can capture even the smallest details, like on this ring.

In contrast to digital projector primarily based resin printers, whose accuracy is decided by the decision of their LCD, the Moai is an analog system. The laser is aimed by two mirrors mounted on galvanometers. The galvanometers are pushed by a sign from a 16 bit DAC. Which means that the theoretical most positioning accuracy is 2 microns.

Who’s Peopoly?

Peopoly (pronounced pee-opoly) is a brand new 3D printing firm based by two pals in 2015; Shu (Mark) Peng and Richard Li. Their objective was to create a laser SLA printer that was inexpensive sufficient for normal makers, not simply professionals. The corporate has operations in Los Angeles, CA and Hong Kong.

In March 2017 they launched a Kickstarter marketing campaign for the Moai. The marketing campaign was efficiently funded in April and so they started delivery printers to backers in July of the identical yr.

The Construct

The Moai takes about 6 hours to construct, from taking it out of the field to doing all of your first take a look at print. You may get your Moai and begin printing with it the identical day.

The key elements of every Moai are assembled on the manufacturing unit, calibrated, examined, after which taken aside and put within the field for you. The construct is straightforward since you are simply combining subassemblies. The package comes with all of the instruments you will want. No soldering or different specialised expertise are required. All of the troublesome work has already been completed for you.

Open Ecosystem

Many SLA printers require you to make use of resin made by the printer’s producer, however the Moai doesn’t. It lets you regulate all laser energy and publicity settings, which signifies that you should use any resin you need with it. We advocate getting the Peopoly resin to start out off with, because the default settings are tuned for that resin and it’ll work greatest when you find yourself attempting your printer for the primary time. Nevertheless after you have some expertise with the machine you may attempt any of the opposite resins we supply, just like the MakerJuice or the PhotoCentric resin. Simply do not forget that every resin is totally different, although, so you will want to do some experimentation to get the settings proper.

Peopoly resins additionally work in printers aside from the Moai. Particularly, their resin works properly with the Type 1. The Moai resin vat can also be interchangeable with the vat from the Type 1.

Prints with G-Code

One factor we notably like in regards to the Moai is that it prints utilizing common G-Code, identical to an FFF printer. Which means that it is going to work along with your favourite slicing program. In contrast to most SLA printers, you aren’t locked in to utilizing the software program supplied by the printer’s producer. Peopoly has a specifically tuned model of Cura that they advocate, however you may also use MatterControl or Slic3r.

All in all, the Peopoly Moai SLA resin 3D printer is an superior machine that will get extremely detailed prints, would not take lengthy to construct, and extra importantly, would not break the financial institution!
