A team at Northwestern University might have just cracked the code on how to utilize stereolithography printing systems as an efficient manufacturing tool using their machine, HARP (short for high-area rapid printing).
HARP is a specialized 3D printer, just received a record-breaking throughput for modern 3D printing. This 3D printer can create structures the size of a human adult in just a couple of hours.
With this new technology we will finally have the fast, precise and versatile 3D printing device we’ve been waiting for.
In the past, researchers have struggled to make SLA printing machines that are larger,faster and able to monitor their temperature to ensure the machine doesn’t emit a hazardous amount of heat.
Enter: Northwestern’s HARP.
HARP’s success hinges on its innovative design, one that’s capable of thermostatic control.
Find out more about how the team at NU came up with this solution and learn about HARP’s many additional special features in this Elements.

Why This 3D Light Printer Is a HUGE Game Changer - https://youtu.be/Yy-d5VVZlxQ
Rapid, large-volume, thermally controlled 3D printing using a mobile liquid interface
"We report a stereolithographic three-dimensional printing approach for polymeric components that uses a mobile liquid interface (a fluorinated oil) to reduce the adhesive forces between the interface and the printed object, thereby allowing for a continuous and rapid print process, regardless of polymeric precursor. "
Highest-throughput 3D printer is future of manufacturing
"Called HARP (high-area rapid printing), the new technology enables a record-breaking throughput that can manufacture products on demand. Over the last 30 years, most efforts in 3D printing have been aimed at pushing the limits of legacy technologies. Often, the pursuit of larger parts has come at the cost of speed, throughput and resolution. With HARP technology, this compromise is unnecessary, enabling it to compete with both the resolution and throughput of traditional manufacturing techniques."
3-D printer can build meter-tall objects in just a few hours
"The researchers used their device to build a 38 cm x 61 cm x 76 cm lattice structure out of urethane acrylate resin, taking just 105 minutes to complete the build. That is the highest throughput achieved by any stereolithography system, Mirkin says."
