What Materials Can the Lynxter S300X Print?

Direct answer: the Lynxter S300X can print liquid elastomer systems or thermoplastic filament, but not from one universal stock setup. Lynxter currently sells an S300X - LIQ21 | LIQ11 configuration for silicone and related liquid-material workflows and a separate S300X - FIL11 | FIL11 IDEX configuration for thermoplastic filament. Choose the configuration first, then verify the exact toolheads, material grade, support process, cartridge or spool route, software profile and safety documentation on the quotation.

That distinction is the practical buyer decision. A liquid S300X is not made into a filament machine merely because the chassis shares a name, and the filament configuration does not gain silicone capability from a material-page temperature or viscosity claim. Lynxter promotes an open ecosystem, but open means a route for qualified integration and development, not that every third-party chemistry is plug-and-play.

S300X material compatibility at a glance

The configuration name is part of material compatibility

Lynxter's current product catalog presents two S300X products, not one blank machine with every toolhead included. The LIQ21/LIQ11 page is explicitly a silicone 3D-printing system and emphasizes IDEX support, industrial and medical-grade silicone workflows, and an open ecosystem. The FIL11/FIL11 page is explicitly an IDEX thermoplastic printer and highlights a heated chamber, an integrated dehydration unit, health-conscious design and high-performance materials.

That changes how a purchase request should be written. Do not request only an "S300X" and assume the material list will be resolved later. Name the required feedstock family, support strategy, toolhead pair, cartridge or spool format, software profile, build surface, environmental controls, post-processing and qualification duty. Ask Lynxter or its authorized channel to identify the exact ordered configuration and supported combination in writing.

The shared model name can also confuse owners comparing used or demonstration equipment. Photographs of the enclosure do not establish installed toolheads, pump hardware, dehydration equipment, seals, accessories, software entitlement or service status. Inventory the physical machine and documentation before valuing its material capability.

What the LIQ21 and LIQ11 configuration is for

Lynxter describes LIQ21 as a bi-component liquid toolhead and LIQ11 as a single-component liquid toolhead. Those names describe materially different delivery and cure workflows. A two-component silicone route depends on controlled delivery and mixing of its components; a single-component route has its own storage, extrusion and cure conditions. Neither should be reduced to a nozzle-temperature comparison.

The current liquid S300X product route focuses on real silicone printing and IDEX support. Lynxter's current material pages document SIL-001 and SIL-002 industrial silicone families, while its current catalog also includes other specialized silicone grades. Treat each grade as its own released system. Hardness, mix ratio, cure behavior, working time, adhesion, color, chemical resistance and application claims do not transfer from one silicone merely because both are printable.

PU-001 adds a polyurethane route, but it should not be called interchangeable with silicone. Component chemistry, cure, moisture sensitivity, cleaning, support compatibility, finished properties and safety data can differ. Require the current toolhead and printer pairing rather than inferring compatibility from the existence of a Lynxter material page.

IDEX support changes geometry, not material identity

The second carriage can deposit a support material while the first deposits the build material. Lynxter documents SUP-001 as a water-soluble support for silicone and SUP-002 as a manually removable support for polyurethane. That can open geometries that would otherwise collapse or trap support, but it does not make every build-material/support-material pair valid.

Confirm the exact pairing, toolhead assignment, interface gap, deposition sequence, cure timing and removal process. A soluble support still needs a controlled wash or dissolution route and waste plan. A breakaway support still needs access for removal without tearing soft walls or damaging the surface. Internal channels, sealed cavities and patient- or food-contact geometries can create removal and residue questions that a successful print does not answer.

Gel-supported or free-form silicone work is also a distinct process route. Treat gel identity, containment, recovery, cleaning and residue control as part of the material system. Do not generalize an application demonstration into a universal claim for every silicone, geometry or regulated use.

What the FIL11/FIL11 configuration is for

The current FIL11/FIL11 product page establishes the thermoplastic branch of the S300X family. Its useful buyer features are not just maximum temperatures: the heated chamber, integrated dehydration unit, IDEX modes and health-conscious design affect which filament workflows are practical and repeatable. Exact capability still follows the current material release, nozzle and profile rather than a temperature ceiling alone.

Lynxter's current thermoplastic material pages include PLA-001, PETG-001 and PA-001. The PETG grade is described as glass-fiber reinforced, and PA-001 as carbon-fiber-reinforced polyamide 6. Those descriptions create an abrasion boundary. Confirm that the installed nozzle and all wear-sensitive feed components are approved for the exact grade. A hardened-looking nozzle or a sufficiently high temperature is not proof of manufacturer support.

Drying is also material-specific. The integrated dehydration unit is relevant, but its presence does not establish a universal temperature, time or storage rule. Use the current material instructions and keep filament sealed after drying. Moisture history can affect extrusion stability, surface finish, dimensions and properties, particularly for nylon. Record spool identity, lot, drying cycle, exposure and reuse when repeatability matters.

IDEX can support duplicate, mirror, dual-material or support workflows, but every pairing needs compatible thermal, adhesion and purge behavior. Two independently printable filaments may still make a poor pair if their chamber, bed, shrinkage, interface or removal requirements conflict.

Open materials are development work

Lynxter promotes open material compatibility and collaboration on custom silicone formulations. That is valuable for organizations with a real development program, but "open" is not the same as "validated." A third-party liquid needs suitable viscosity or rheology, particle content, component ratio, cure mechanism, pot life, storage, cartridge or pump compatibility, seal compatibility, cleaning method and safety documentation. A third-party filament needs suitable diameter, stiffness, melt behavior, abrasion level, drying, chamber, surface and profile.

Define who owns the parameter set, toolhead wear, contamination, failed material, cleaning, software changes and warranty implications. Preserve material and process versions. A material that deposits once may still fail on repeatability, dimensional control, aging, fatigue, sealing, sterilization, chemical exposure or supplier change.

Development should have a release gate: representative geometry, agreed inspection, documented process window, material traceability, change control and a finished-part test plan. Manufacturer application examples remain scoped examples, not independent proof for a new design.

Safety, facility and chemical boundaries

Read the current Lynxter machine instructions and the safety data sheet for every build, support, cleaning and post-processing material. Liquid silicone, polyurethane components, support media, solvents and cleaning agents can require different gloves, eye protection, ventilation, spill response, storage and waste handling. Do not assume a cured elastomer's low-hazard reputation describes its uncured components.

Maintain guards, doors, interlocks, pressure limits, pumps, tubing, electrical protection and emergency controls. Keep ignition sources and incompatible chemicals controlled. Do not bypass enclosure or filtration features, improvise pressure vessels, service energized equipment or mix materials outside the documented process. Use trained personnel and lockout or service procedures where required.

Thermoplastic printing can release particles and volatile compounds, while reinforced filaments can add dust during trimming, sanding or machining. Use source control and ventilation appropriate to the material and task. NIOSH recommends engineering controls such as ventilation and high-efficiency filtration for additive manufacturing, but that general guidance does not replace Lynxter instructions, safety data sheets or a site-specific industrial-hygiene and fire review.

Medical-grade, food-grade, biocompatible, flame-resistant or chemically resistant material wording is always scoped. It does not make every printed geometry, surface condition, cleaning method or production workflow approved. Preserve the exact material certificate and test basis, then qualify the finished part under its governing use.

Finished-part qualification is separate from printability

A completed print proves deposition, not fitness for service. Record the machine configuration, toolhead, software and profile, material and support lots, component ratio or drying history, orientation, cure or thermal history, support removal, cleaning and post-processing. Requalify affected outputs after material, toolhead, cartridge, nozzle, software or supplier changes.

For soft parts, examine wall thickness, voids, seams, cure, tear initiation, compression set, fatigue, fluid exposure and cleaning. For reinforced thermoplastics, examine orientation, layer bonding, moisture, notches, fasteners, creep, heat, fatigue and abrasive wear. Pressure, lifting, structural, medical, food-contact, electrical and safety-critical parts require responsible engineering and any applicable standards.

Buyer and owner decision

• Choose S300X LIQ21/LIQ11 when real silicone or a documented liquid-elastomer workflow is the core job and the organization can own cartridges or pumps, mixing or cure, matching support, cleaning, chemistry safety and finished-part qualification.
• Choose S300X FIL11/FIL11 when IDEX thermoplastic printing, a heated chamber and integrated material conditioning match the job. Confirm exact grade, abrasive hardware, drying, chamber and surface requirements before ordering.
• Request a written configuration matrix when the business case depends on PU-001, a specialized silicone, a reinforced filament, a support pairing, a third-party material or an installed option not clear from the current product page.
• Treat open materials as a development program, with process ownership, safety review, traceability, change control and a release test plan.
• Choose another thermoplastic platform when the work centers on a different high-temperature filament ecosystem; compare the INTAMSYS FUNMAT PRO 410, AON3D Hylo and CreatBot PEEK-300 material boundaries.
• Choose continuous-fiber reinforcement when that process, rather than chopped-fiber filament or liquid elastomer, is the requirement; the Markforged FX20 material guide owns that different decision.

For an uncertain part, start with the custom-part material decision guide and the custom 3D printing service FAQ. For a defined job, request a GoodPrints quote; for repeat production or broader equipment access, use the JC Print Farm route.

Bottom line

The Lynxter S300X has a broad material story only after you separate its two current configurations. Buy LIQ21/LIQ11 for documented liquid silicone and related elastomer workflows; buy FIL11/FIL11 for thermoplastic filament. Then validate the exact material, support, toolhead, cartridge or spool, environment, safety controls and finished-part duty. Do not buy the shared chassis name and assume the chemistry will sort itself out.
