This specialized 3D printer just received a record-breaking throughput for modern 3D

It can create structures the size of a human adult in just a few hours.

That’s printing about 7 millimeters per minute.

With this device, the team may have just cracked the code on how to utilize the technology

This means we will finally have the fast, precise and versatile 3D printing device we have

It just took a little bit of thermostatic control to get there.

Firstly, this particular 3D printing process is called Stereolithography or SLA.

SLA printing is considered one of the higher-end 3D printing technologies because the objects

can have smooth detailed features, with obvious precision, and can be made with a variety

They work by using a light-reactive thermoset resin, which, when exposed to certain wavelengths

So layer by layer, the object is solidified while pulled out vertically from a vat of

As awesome as these printers are, researchers have had trouble making the machines larger and faster.

CHAD MIRKIN: So here's the interesting thing when you go fast and you go large, you can

really change the way we think about manufacturing.

If you really want to be able to make inroads, you want to be able to make large batches

and large parts in addition to small parts.

That's what this printer allows you to do.

Their machine is known as HARP—short for high-area rapid printing.

Its success hinges on its innovative design, one that’s capable of thermostatic control

CHAD MIRKIN: We have a liquid, think of it as liquid Teflon, that basically flows over

the glass window, that the light is shining through to generate the part that nonstick

liquid is keeping the part from adhering to the window, allowing you to continuously print,

which gives you speed, and it is removing the heat, as it's generated.

So we're almost unlimited in terms of size, and in principle.

With HARP’s fluorinated oil, it can do it with at least three different kinds:

hard plastic, elastic rubber, or ceramic.

CHAD MIRKIN: We can make all sorts of materials that are important in the medical industry,

we're talking about the dental industry to tennis shoes soles to car parts to airplane

We can make construction parts, really almost

anything that you can imagine and make out of polymer precursors and that's a lot of

And its special features don’t stop there.

HARP is also able to print both large and small items, which is unprecedented in the

Usually the size of the printer determines the tasks that it can handle and it varies

from waiting for hours to days for a final product.

All together, HARP is reportedly said to be the largest and highest throughput printer

CHAD MIRKIN: The amazing thing about this technology is the pace at which it's being

We're going to have commercial printers within 18 months.

We are now on a Gen three printer that actually prints even higher quality structures than

Pretty exciting and really rapid development.

Up until this point, 3D printing has been restricted practically, while remaining powerful

With a printer like this, the team could be spearheading a future without limitations.
