What your process engineer actually checks
What your process engineer actually checks
Formulated to print, then perform
A low-viscosity silicone extrudes cleanly through a DIW paste head and holds its bead, then cures at low temperature into a flexible part. The hardness is tunable across 20–80 Shore A, and cured parts hold up from −50 °C to 200 °C — soft where you need compliance, firm where you need structure.

About this product
Sygnis silicone for Direct Ink Writing (DIW) is a printable liquid silicone that extrudes cleanly through a paste head and cures at low temperature into a flexible part. Choose a hardness across 20–80 Shore A, and the cured silicone serves from −50 °C to 200 °C.
Why print silicone with DIW
A material that extrudes precisely and performs after cure.
Formulated to extrude cleanly
A low-viscosity silicone flows precisely through a DIW paste head and holds its bead, so you build fine, controlled geometry rather than fighting a stringy or slumping material.
Tunable 20–80 Shore A
Pick soft, compliant parts at the low end of the range or firmer, more structural ones at the high end — one process spanning cushioning, seals and load-bearing flexible components.
−50 °C to 200 °C in service
Cured parts stay functional from deep cold to sustained heat, so seals and flexible components hold up in engineering environments where a standard flexible resin would soften or turn brittle.
Bonds to many substrates
Adheres to aluminium, stainless steel, glass, plastic, rubber and ceramic — so you can print silicone directly onto an existing part (a gasket on a housing, a compliant layer over a rigid base) instead of printing and assembling separately.
How you print it
Load, extrude, cure — on a DIW / paste-extrusion system.
Step 01
Load the paste head
Load the silicone cartridge into your DIW / pneumatic paste-extrusion head, such as a Sygnis F-NIS system.
Step 02
Extrude the geometry
The head lays down the silicone bead-by-bead to build the part — or prints directly onto a substrate for an in-place seal or compliant layer.
Step 03
Low-temperature cure
Cure at low temperature to set the silicone into a flexible, durable part without stressing the substrate or geometry.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is this silicone and what printers is it for?
It is a printable liquid silicone for Direct Ink Writing (DIW), also called paste extrusion or robocasting. A paste head extrudes the silicone bead-by-bead to build up a part, which then cures into a flexible silicone component. It is used with Sygnis DIW systems and paste-extrusion heads, and with other DIW platforms — an Additive Plus engineer can confirm settings for your printer.
How hard are the printed parts?
The silicone covers a 20–80 Shore A hardness range, so you can choose soft, compliant parts (low Shore A) or firmer, more structural ones (high Shore A) depending on the application. Tell us the target hardness and geometry and we will confirm the right grade and print settings.
What temperatures can the cured silicone withstand?
Cured Sygnis DIW silicone has a service range of −50 °C to 200 °C, so printed seals, gaskets and flexible parts stay functional from deep cold to sustained heat. That makes it suitable for engineering environments where a standard flexible resin would soften or become brittle.
What does it bond to?
The silicone adheres to aluminium, stainless steel, glass, plastic, rubber and ceramic substrates. That lets you print silicone features directly onto an existing part or substrate — for example a gasket printed onto a housing, or a compliant layer over a rigid base — rather than printing and then assembling separately.
How does it cure?
The silicone is designed for low-temperature curing after printing, which keeps the process gentle on substrates and printed geometry. Exact cure temperature and time depend on the grade and part thickness — request the datasheet or ask a materials engineer for the cure schedule that matches your parts.
What can I make with it?
Typical applications include seals and gaskets, flexible and compliant parts, soft-robotics elements, damping and cushioning components, wearables, and silicone tooling or molds. Because it prints directly and bonds to many substrates, it also suits low-volume custom parts that would be hard to injection-mold.
How is it supplied and priced?
Sygnis DIW silicone is supplied per configuration — hardness grade and pack size to match your application — so it is quoted rather than sold at a fixed shelf price. Request a quote with your target hardness, volume and printer, and Additive Plus will confirm pricing, pack size and lead time.
