Dear sir, madam, 

At Delft University of Technology, The Netherlands, we\'re making a lot of microfluidic PDMS chips by means of casting over a negative (silicone wafer).  This takes quite a bit of time and money.
We hope your 3D PDMS microchannel printer can be a solution.
Can you send me a quote for a suitable printer. (Model M50-405nm?). Our typical chip sizes are max 75x25x5mm, with channels as small as possible.
Additionally, if you could provide us with a sample of a PDMS microschannel chip, we can check the quality ourselves.

Kind regards,
