3DFacture has introduced a new professional SLA laser 3D printer they have created in the form of the Weaver which offers a 50 micron laser spot but is capable of printing detailed smooth finish objects. Watch the demonstration video below to learn more about the SLA 3D printer that is fitted with a F-theta lens now available to back via Kickstarter with pledges available from $1,099 or roughly £768.
If the Kickstarter campaign is successful and manufacturing progresses smoothly worldwide shipping is expected to take place during June 2018. 3DFracture explains more about the inclusion of the F-Theta lens. “A laser beam usually has a Gaussian intensity profile – intense in the center and reduces towards edge. Optical lenses are used to focus the beam from a few millimetres in diameter where it exits the fibre, down to a narrow waist where it intersects with the build plate. As we move away from this focal point, the beam’s cross-sectional area increases, reaching twice the minimum size at a distance along the beam called the Rayleigh length.”
The Weaver is capable of printing objects up to 150 x 150 x 190 mm in size and offers a resolution of 50 μm in the XY plane and 25 μm in the Z axis and uses a 405nm UV laser to cure photosensitive resin layer-by-layer.
