Sublym - Alternative To Soft-lithography

The Sublym100 is a great alternative to soft-lithography microfabrication, for easy and quick production of your microfluidic devices.

The SuBlym100 is a hot embossing machine, using heat and pressure to mold a variety of materials in a matter of minutes. More specifically, it has been optimized for Flexdym polymer molding in only 2 minutes, but can also be used to mold various other thermoplastics, including PMMA.

Do you require an alternative to soft-lithography microfabrication? Because the Sublym™ hot embossing machine is a great option for easy and quick production of microfluidic chips.

The Sublym™ is a hot embossing machine, using heat and pressure to mold a variety of materials in a matter of minutes, including Flexdym™, COC, PMMA and PS. Consequently, it serves as a great alternative to soft-lithography casting. More specifically, the Sublym100 has been optimized for Flexdym™ polymer molding in only 2 minutes, but it can also be used to mold various other thermoplastics, including PMMA.

Check out below additional advantages of the Sublym™:
  • Easy-to-use, with no extensive training is needed to operate it. The Sublym™ is the perfect equipment for accelerating projects.
  • An ultra-compact design, that’s not much bigger than a laptop. The Sublym™ is dramatically smaller than standard commercial hot embossing machines, weighing up to 500 kg.
  • A user-friendly system, that is only powered by electricity. You can plug-and-play in the smallest of spaces.
  • Dramatically cheaper than other microfabrication equipment. The Sublym™ makes microfluidics more accessible to everyone.
4 Easy steps to create Flexdym chips using the Sublym™:
  1. Cut a Flexdym™ sheet to the size of your device.
  2. Next, mold the sheet by placing the sheet, between your mold and the counter mold (included in the Sublym kit), inside the machine.
  3. Then, unmold the sheet and create inlet/outlet ports. Check out our metal punch pliers for this step.
  4. Finally, laminate sheet onto substrate. Flexdym™ can bond to various materials including, itself, glass, PDMS, PS, PC, COC, COP and PMMA.

A note to our Flex users: the Sublym also serves a great bonding aid for standardized Flexdym™ chip bonding.

This microfabrication countertop companion allows quick prototyping and production of microfluidic chips at a push of a button! What else could you need?

The Sublym vs. A Hot Press

Sublym hot embossing machine GIF

Sublym Machine


Optimized for Flexdym molding in only 1-2 minutes!


Compact & User-friendly design that requires little to no training.


Dramatically cheaper than most standard clean room equipment. This small investment is an opportunity for you to begin exploring microfluidics.

Classic Hot Press


Not optimized for Flexdym molding, therefore longer  molding time.


Less easy to use alternative for the Sublym.


Slightly more expensive than the Sublym100, but a standard piece of equipment which is generally installed in fabrication facilities.

Molds For Hot Embossing

Expoxy-resin mold | Eden Tech

Epoxy Resin Mold

One of the the best options for hot embossing, remains robust through repeated molding cycles. Our Epoxym kit enables the fabrication of epoxy mold replicas from Silicon wafers.

Glass Mold

Glass Mold

Etched glass molds are another robust option for hot embossing. 

Metal Mold

Metal Mold

Metal molds, such as those made from aluminium, are a robust option. 

Silicon Wafer

Silicon Wafer

The least ideal option for hot embossing are SU-8 & silicon wafers, due to their fragility and ease of breakage. However, when carefully handled and coated with non-stick spray, they may do the trick.

Brochures & Documents

Flexdym is our original and patented material, developed by our CEO Emmanuel Roy. Unlike other materials used in microfluidics device fabrication, Flexdym is the first material created specifically for microfluidics biomedical applications. Our Sublym hot embossing machine was then created to render device replication fast and easy. It is compact, user-friendly and affordable. Finally, our Epoxym kit produces robust mold replicas from silicon wafer molds. For more information on any of these products, check out our brochures below.

    Scientific Publications

    Flexdym users worldwide are publishing their microfluidics research in top peer reviewed journals including, Nature, Advanced Materials, Analytical Chemistry, Lab on Chip and more. The topics also vary from cell culture and point of care diagnostics, to flexible electronics, wearable devices and micromixers. For a copy of our publications contatc us below!
