It comes as no surprise that the 3D printing industry is constantly evolving. Generation after generation, new toys are introduced to the scene — the highest technology is incorporated to ensure that the new product is even better than its predecessor. In this case, we’re going to see how Low Force Stereolithography (LFS) technology brings something special to the table.
The introduction of Formlabs’ new printers the Form 3 and the Form 3L have brought a created a whole different ball game. Thanks to their LFS technology, you can create highly advanced 3D prints that are better than ever before. Not only can you create fantastic parts, but they also cost effective and allow for production-ready applications with higher production volumes. Let’s take a closer look.
Before getting down to the basics, let’s talk about SLA 3D printing. We’ve already given you some information about this in previous posts, but there’s no harm in refreshing your memory.
As opposed to DLP 3D printers, where a digital projector screen is used to display an image of a layer across a built-in platform, a laser is incorporated in SLA 3D printers. The laser is aimed towards two mirror galvanometers so that the light falls on the right coordinates. The light is pointed upwards, to cure the solid isotropic parts of liquid photopolymer resin.
Moving on to LFS Low Force Stereolithography, it’s best described as SLA’s successor; in this case, it uses a flexible tank and linear illumination to transform liquid resin into new, pristine parts. The more flexible the tank, the lower the force.
In the long run, this not only ensures quality prints and also printer reliability. The detail simply needs to be seen to be believed. Besides the incorporation of state-of-the-art materials, these printers are also made in such a way that support removal is as easy as 1, 2, 3.
A Low Force Stereolithography LFS 3D Printer is made up of 3 main components:
For starters, these LFS printers work great for large format 3D prints. Furthermore, you can create the perfect balance of speed and detail through its adaptive print speed option.
Taking a look at some of the features, the laser spot found in these printers ensures precision and accuracy, while its parabolic mirror guarantees more uniformity across the built-in platform.
LFS printers are also easy to clean; since a flexible thank is incorporated, it allows for a soft release with minimal support. Additionally, there is also a user-replaceable LPU with garage mode to protect optics.
Lamborghini adopts 3D printing and prints more than 20,000 parts in 2020 Italian luxury car and SUV manufacturer Lamborghini is widely known for being ahead of the curve by implementing the latest technologies to the automobile market. Therefore, it came as no surprise when Lamborghini decided to 3D print car parts. By integrating 3D printing with traditional car-making methods, Lamborghini is creating timeless masterpieces - such as the Lamborghini Sián FKP 37 and the Sián Roadster - and showing everyone how it's done.
Artforge Studio Uses FabPro 1000 to Expand Capabilities with 3D Printed Jewellery The UK-based jewellery workshop Artforge Studio is quickly becoming the epitome of modern jewellery making. The Studio's owner, Simon Walker, has been a working goldsmith for over 30 years. However, recently, Walker introduced 3D Printing to his classic jewellery making process. The combination of 3D printing with traditional methods such as diamond mounting and silversmithing has taken Artforge Studio to the next level.
3D Printing for Product Design: the Full Details 3D printing is the future of product design. It can take a product from initial design brainstorm, to the implementation of final details in the creation of a product and straight down to the final marketing and sales phase. The benefits of 3D printing for product design are endless, and with the technology in its infancy, there are a myriad of other opportunities to be explored.
