PμSL
Projection Micro Stereolithography (SLA)
Based on the principles of stereolithography (SLA), this technique allows for rapid photo polymerization of an entire layer of resin with a flash of UV light at micro-scale resolution allowing us to achieve ultra-high accuracy, precision and resolution that cannot be attained with other technologies.

RESOLUTION

How small a part or feature can be printed

ACCURACY

How close does the part or feature match the intended size

PRECISION

How repeatable is the printing process
We have been following the advancements of 3D printing very closely over the years. Until recently, there has not been a rapid process that could produce micro parts, with micro features and micron tolerances that our customers expect from a prototype. We believe high-precision 3D printing like this can be very complementary to serving the needs of our customers.

We are very excited to own the 1st S130 Micro Stereolithography 3D printer in Europe. The S130 machine from BMF has a good compensation between printing resolution and processing speed, which provides us a fantastic tool in production of customized geometries with a volume of centimetres at a few micron resolution. The arrival of this machine will help boost our current research 3D print electronic as well as biomedical directions.
Dr. Yinfeng

The parts say it all. The first time you see a part from a BMF printer you will be amazed. 3D printing, until now, has never been able to produce parts of such precision, and accuracy. Being able to capture thin walls and fine features at this scale and resolution, with unmatched reliability, is unprecedented from any 3D printing technology. This will absolutely usher in new industries, that have previously ignored 3D printing, to the world of rapid design iteration.
