Form 3 is a 3D resin printer that uses enhanced SLA technology. Formlabs, manufacturer more than known in the world of 3D printing, has reinvented its SLA technology to obtain impeccable prints in all the fabrications. Form 3 is characterized by prototypes on a larger scale with a printing volume of 145x145x185 mm and by the manufacture of industrial quality end pieces at a really affordable price.
The new LFS (Low Force Stereolithography) printing technology uses linear lighting and a flexible tank to convert liquid resin into solid parts. The part responsible for lighting is the LPU (Light Processing Unit), a single module that contains all the parts (lenses, mirrors and lasers) that are needed to solidify the resin during the manufacture of a piece with a laser power of 250 mW and a precision in an XY plane of 25 μm. This new system offers clear and clean features thanks to the high-power laser passing through a filter and guarantees a concentrated laser point. The parabolic mirror ensures that the projection of the laser on the manufacturing plane is always perpendicular, which ensures maximum print quality and the exact reproduction of the design to be manufactured. But here the advantages of the LPU do not end, a new high frequency galvanometer offers precise control over the laser and a high speed, reducing printing times. The operation of this module can be clearly seen in the following video.
Continuing with more technological advances, the Form 3 has a large number of integrated sensors that constantly monitor the impressions. These sensors also help to keep all fabrications stable and inform the user of the status of the printer through alerts. Within the LPU module there are optical sensors that constantly correct the amplitude, the power and even detect the presence of dust, something fatal for the operation of the laser. A new resin level sensor quickly and reliably detects all materials, which speeds up the change of resin. Like Form 2, has an automated heating system that maintains uniformly the temperature of the resin to promote its curing. Finally, a new sensor, located in the area of the build platform, ensures that printing starts smoothly.
Formlabs is always thinking about facilitating the work to its users. In models of previous 3D printers, for example the Form 2, it is very easy to change the resin tank and the build platform. At higher with Form 3, Formlabs has been overcome by designing a large number of elements that can be replaced by the user, the LPU module as the rollers and the optical window. This drastically reduces repair time.
With the 3D resin printer Form 3 you can create models easily and quickly. Simply enter the CAD file in STL or OBJ format the PreForm lamination software. This software automatically prepares the supports and allows you to send the impressions to Form 3 over Wi-Fi very easily. Once the printing is finished, the supports are removed and the pieces are transferred to the washing center (Form Wash) and then to the curing center (Form Cure). At the end of these simple steps, the pieces would be ready for use.
As a summary of everything seen above we can say that Form 3 is a 3D resin printer ready for use from the first minute and with everything necessary to obtain quality parts quickly and easily, even if you do not have prior knowledge on resin 3D printers.
