Imagine a 3D printer that can create objects as large as a human adult in just a few hours. This is no longer a futuristic dream but a reality, thanks to a groundbreaking 3D printer that sets new records in speed and efficiency. This innovative device prints at an impressive rate of about seven millimeters per minute, potentially transforming 3D printing into a powerful manufacturing tool. The key to this advancement lies in improved thermostatic control, which has finally brought us the fast, precise, and versatile 3D printer we’ve been waiting for.
To appreciate this technological leap, let’s delve into the 3D printing process known as stereolithography, or SLA. SLA is a high-end 3D printing technology renowned for producing objects with smooth surfaces, intricate details, and high precision. It uses a light-reactive thermoset resin that solidifies when exposed to specific ultraviolet light wavelengths. The object is formed layer by layer, emerging vertically from a vat of resin.
Despite the impressive capabilities of SLA printers, scaling them up in size and speed has been a challenge. However, achieving both speed and size can revolutionize manufacturing, allowing for the production of both large and small parts efficiently.
Enter HARPS, which stands for High Area Rapid Printing. This machine’s success is attributed to its innovative design, particularly its thermostatic control of the large vat of liquid resin. A non-stick liquid, akin to Teflon, flows over the glass window through which light passes to form the part. This liquid prevents the printed part from sticking to the window, enabling continuous printing and efficient heat removal. Theoretically, this allows for the creation of objects of almost unlimited size.
HARPS is versatile, capable of working with at least three different materials: hard plastic, elastic rubber, and ceramic. This adaptability is crucial for various industries, including medical applications, dental products, footwear, automotive parts, and construction components. Essentially, HARPS can produce a wide array of items from polymer precursors.
What sets HARPS apart in the 3D printing world is its ability to print both large and small items, a feat previously unheard of. Typically, a printer’s size limits the tasks it can handle, often leading to long wait times for final products. HARPS, however, is reportedly the largest and highest throughput printer in its class, breaking these limitations.
The rapid development of this technology is truly exciting. We can expect commercial versions of these printers within 18 months, with the current Gen 3 printer already producing higher quality structures than those documented in existing scientific literature. This progress suggests a future where 3D printing is no longer constrained by previous limitations.

This specialized 3D printer has achieved a record-breaking throughput for modern 3D printing. It can create structures the size of a human adult in just a few hours, printing at a rate of about seven millimeters per minute. With this device, the team may have found a way to utilize the technology as an efficient manufacturing tool. This means we will finally have the fast, precise, and versatile 3D printing device that many have been anticipating. It just took some advancements in thermostatic control to get there.
Let’s rewind a bit. This particular 3D printing process is called stereolithography, or SLA. SLA printing is considered one of the higher-end 3D printing technologies because it produces objects with smooth, detailed features and high precision, using a variety of materials. The process works by using a light-reactive thermoset resin, which polymerizes when exposed to specific wavelengths of ultraviolet light. Layer by layer, the object is solidified while being pulled vertically from a vat of resin.
As impressive as these printers are, researchers have faced challenges in making the machines larger and faster. However, when you combine speed and size, it can significantly change manufacturing capabilities. The ability to produce large batches and large parts, in addition to small parts, is what this printer enables.
The machine is known as HARPS, which stands for High Area Rapid Printing. Its success relies on its innovative design, capable of thermostatic control of the large vat of liquid. This liquid, similar to Teflon, flows over the glass window that the light shines through to generate the part. The non-stick liquid prevents the part from adhering to the window, allowing for continuous printing, which enhances speed and removes heat as it is generated. In principle, this allows for almost unlimited size.
With HARPS’ fluorinated oil, it can work with at least three different types of materials: hard plastic, elastic rubber, or ceramic. This versatility is crucial for various industries, including medical applications, dental products, footwear, automotive parts, and construction components. Essentially, it can produce a wide range of items made from polymer precursors.
HARPS is also capable of printing both large and small items, which is unprecedented in the 3D printing world. Typically, the size of the printer dictates the tasks it can handle, often resulting in long wait times for final products. HARPS is reportedly the largest and highest throughput printer in its class.
Looking ahead, the pace of development for this technology is remarkable. We can expect commercial printers within 18 months, and we are currently on a Gen 3 printer that produces even higher quality structures than those in existing scientific papers. This rapid development is exciting. Until now, 3D printing has been somewhat limited, but with advancements like this, the team could be leading us toward a future without such constraints.
