Printing Silicones on the Sygnis F-NIS and Sygpast – DIW Guide
Print your own silicone — the Sygnis F-NIS 23151 and Sygpast are open DIW platforms for one- and two-component silicones you formulate or buy.
- One-component, moisture-curing and UV-curing silicones on the F-NIS
- UV 365/405 nm, 60 °C heated cartridge, cooled platform or two heads by version
- Two-component silicones and supported soft parts on the Sygpast
- K2 silicone in the box for calibration · you source the production material
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.
A materials engineer on the line
Not a ticket queue. We run DIW and paste extrusion in-house, so nozzle, flow and cure advice for your printer comes from the floor.
- One-component silicones that are semi-liquid or paste-like — dosed straight from a tube into the cartridge
- UV-curing silicone and acrylic systems — with the UV 365/405 nm module (F-NIS Version B and up)
- Moisture-curing silicones — acetoxy, oxime, alcohol-based and acidic cure
- Filled silicones, such as carbon- or silver-filled
- Two-component materials — on the Sygpast with its SLE2 head
- A standard K2 silicone ships with every F-NIS for commissioning and calibration
Which silicones the Sygnis printers print
The F-NIS 23151 and the Sygpast are Direct Ink Writing (DIW) printers: air pressure pushes a material from a syringe cartridge through a Luer Lock nozzle, and the bead holds its shape on the platform. Sygnis built the F-NIS to print ceramics, silicones and other one-component pastes; silicone seals are one of the applications named in its user manual. Because extrusion is pneumatic, there is no screw or melt to design around — silicone dosed from an ordinary tube fills the cartridge directly.
Sygnis’s materials document gives silicone printed parts for seals, gaskets and vacuum suction cups printed directly onto aluminum, stainless steel, glass, plastic, rubber and ceramic, with operating temperatures from −50 °C to 200 °C and hardness from 20 to 80 Shore A. These figures describe the silicones used, not the printer: hardness, temperature range and adhesion come from the silicone you choose.
Silicone classes and the version that prints them
| Silicone | Printer |
| One-component, room-temperature semi-liquid | F-NIS A and up |
| Carbon- or silver-filled silicone | F-NIS A and up (Sygnis material analysis) |
| UV-curing systems — acrylic, epoxy, acrylic-urethane | F-NIS B and up, cured between layers at 365 or 405 nm |
| Moisture-curing — acetoxy, oxime, alcohol-based, acidic | F-NIS A and up; cures in air after printing |
| Silicone whose flow depends on temperature | F-NIS C, D or E — 10 ml cartridge heated to 60 °C |
| Material that must stay below room temperature on the platform | F-NIS D — platform from −15 °C to ambient |
| Two silicones, or silicone plus another paste, in one part | F-NIS E — two heads, separate heating and pressure |
| Two-component silicone, or soft parts that need supports | Sygpast — SLE2 two-component head, FFF supports, UV and IR curing |
Process parameters from the Sygnis documents
| Pressure | up to 4 bar (400 kPa); calibration starts at 0.100 MPa |
| Material flow | 0.5–1.5 ml/min |
| Nozzles | Luer Lock, 0.10–1.50 mm; calibration files use 0.41 mm |
| Resolution | Z 0.1 mm · XY 0.2 mm |
| Cartridges | 30 / 55 ml; 10 ml heated to 60 °C on C, D, E |
| Platform | tempered glass to 120 °C (A, B, C, E); cooled −15 °C to ambient (D) |
| UV | 365 and 405 nm; exposure time, power, layer spacing and height set in the post-processor |
| Work field | F-NIS 230 × 150 × 150 mm · Sygpast 250 × 250 × 250 mm |

Getting a new silicone to print
Where the printer stops — and what you bring
The printer does not come with production silicone. You source or formulate the material, and its datasheet — cure, hardness, temperature range, biocompatibility, food contact — is the supplier’s, not Sygnis’s or ours. The K2 silicone in the box is for commissioning and calibration only. The F-NIS prints one-component materials; for two-component silicones mixed at the head, or soft parts that need supports, take the Sygpast. Very stiff pastes may need more than the standard 4 bar; Sygnis has built higher-pressure versions (6, 8 or 10 bar) as custom modifications, quoted case by case. For ceramic slurries see printing ceramic pastes on the F-NIS and Sygpast.
