Sygnis F-NIS 23151 DIW 3D Printer
Direct Ink Writing (DIW) Simple and intuitive semi-liquid 3D printing.
Sygnis F-NIS 23151 Direct Ink Writing (DIW) 3D Printer
The Sygnis F-NIS 23151 is a Direct Ink Writing (DIW) 3D printer developed for laboratories, universities and industrial R&D teams working with their own pastes, gels and semi-liquid materials. Built around a fully enclosed platform with pneumatic extrusion, it provides a practical system for material development, proof-of-concept work and prototyping with formulations that cannot be processed using conventional filament-based 3D printing.
The F-NIS supports materials including silicones, ceramic and zeolite pastes, UV-curable resins, conductive pastes and other custom formulations. It uses standard Luer Lock dispensing hardware and works with Simplify3D or PrusaSlicer, with the supplied SYGNIS post-processor adapting standard G-code for pneumatic material deposition and compatible curing functions.
Five configurations are available: Versions A, B, C, D and E. The range progresses from single-material pneumatic extrusion through UV curing, heated cartridges, cooled-platform printing and independent multi-material deposition.
Five Configurations, One Upgradeable DIW Platform
Start with the extrusion capability required for your current research and expand the system as your material development changes. F-NIS configurations can be upgraded to higher-class parameters without replacing the complete printer.
Controlled Extrusion for Semi-Liquid Materials
The F-NIS uses direct pneumatic pressure on disposable Luer Lock cartridges rather than a screw or mechanical plunger passing through the material. This simplifies material changeovers and helps reduce cross-contamination when testing different formulations.
A single-head configuration supports a stated material viscosity range of 20–1000 Pa·s, allowing the same extrusion system to process materials ranging from relatively thin gels to dense pastes. Standard Luer Lock compatibility also gives researchers access to a broad selection of nozzle sizes without relying on a proprietary dispensing interface.
- Nozzle diameter range: 0.11–1.60 mm
- Operating pressure: up to 4 bar
- Material flow: 0.5–1.5 ml/min
- Working area: 230 × 150 × 150 mm
- Working chamber: fully enclosed
Sygnis F-NIS Versions A to E
The five F-NIS configurations are designed around different material processing requirements. Versions A to C provide a progressive route from standard pneumatic extrusion to UV curing and heated cartridges, while Versions D and E introduce temperature-controlled build surfaces and more advanced multi-material processing.
F-NIS Version A
Standard pneumatic DIW configuration.
Version A uses a single pneumatic head with 30 ml or 55 ml cartridges and a heated tempered-glass platform capable of reaching 120°C. It is intended for one-component pastes and semi-liquid materials that do not require UV curing or cartridge heating.
F-NIS Version B
Pneumatic extrusion with in-process UV curing.
Version B adds a dual-wavelength 365 nm / 405 nm UV module. The UV diodes are controlled through the SYGNIS post-processor, allowing compatible materials to be cured during the printing process rather than only after the part has been completed.
F-NIS Version C
UV curing with heated 10 ml cartridge support.
Version C adds a 10 ml cartridge extrusion system with heating up to 60°C, alongside support for 30 ml and 55 ml cartridges. This provides additional process control for formulations whose flow behaviour benefits from controlled heating.
F-NIS Version D
Cooled-platform printing from -15°C to ambient temperature.
Version D combines heated-cartridge and UV capabilities with a cooled aluminium working platform. The platform can operate from -15°C up to ambient temperature, supporting materials that may gel, cure or slump when processed at normal room temperature.
F-NIS Version E
Two-head configuration for multi-material DIW.
Version E is designed for two-material workflows. It provides two heads, independent pneumatic control and independent heating up to 60°C for the supported cartridges, together with a shared 365 / 405 nm UV curing module.
This makes Version E suitable for applications such as two-component pastes, multi-material structures and flexible electronics where, for example, a conductive track and dielectric material need to be deposited within the same printing process.
Heating, Cooling and UV Curing
Temperature control is a major part of the F-NIS platform. Versions A, B, C and E use a tempered-glass build platform heated up to 120°C, while Versions C, D and E also support 10 ml cartridge heating up to 60°C. Version D replaces the heated glass platform with a cooled aluminium platform operating from -15°C to ambient temperature.
Versions B through E also include 365 nm and 405 nm UV capability. The UV system is controlled by the SYGNIS post-processor, enabling curing to be incorporated directly into the print sequence for compatible photosensitive materials.
Software and DIW Workflow
The F-NIS can be prepared using familiar slicing software including Simplify3D and PrusaSlicer. SYGNIS supplies a dedicated post-processor that adapts the generated G-code to the behaviour of the pneumatic extrusion system and controls additional functions such as UV curing where fitted.
This allows laboratories to work with established slicing workflows while retaining the additional process control required for semi-liquid and paste-based materials. Print files can be handled by USB or SD card.
Typical F-NIS Applications
Materials Research & Development
Develop and evaluate new semi-liquid formulations, gels, silicones, functional pastes and other materials where conventional filament or resin printing systems are unsuitable.
Flexible Electronics
Deposit conductive tracks, dielectric layers and other functional materials, with Version E providing independent multi-material control for more complex electronic structures.
Ceramics & Functional Pastes
Process ceramic, zeolite and other high-viscosity pastes for technical components, proof-of-concept parts and laboratory-scale material development.
Pneumatic Control and Optional Compressor
The F-NIS operates using pneumatic extrusion at pressures of up to 4 bar. SYGNIS also offers a matched compressor designed for use with the printer, removing the need for laboratories to source and match their own pneumatic supply.
The available F-NIS compressor provides a 6 bar supply, a 3.5 litre tank, automatic start and stop at approximately 3–4 bar, a stated operating noise level of 45 dB and a weight of 7.1 kg.
