Underhood sensor housings produced from the Rigur system, where RGD525 forms the rigid primary phase and FLX930 supplies secondary compliance domains, are evaluated for short-dwell exposure below the published heat deflection temperature of 63–65 °C at 0.45 MPa under ASTM D648. The actual jetting ratio between primary and secondary is not disclosed as an open mass fraction; the print manager commands a fixed digital material preset through Shore D selection, and the FLX930-rich zones are limited to snap-fit roots, cable clips, and connector latch arms where crack initiation in unfilled high-temperature photopolymer would otherwise occur. The rigid phase provides the low-creep geometry needed for socket retention, while the elastomeric secondary phase redistributes assembly strain away from gate vestiges and sharp internal radii. On multi-material PolyJet equipment, the housing is built with a 3.0 mm nominal wall and honeycomb infill to reduce mass without sacrificing printed stiffness. Support removal with water-jet pressure below 50 bar is required because FLX930-rich surfaces erode if exposed to higher pressure or elevated water temperature. Printed specimens are conditioned at 23 °C and 50 % RH for 24 h before tensile verification, since polyurethane-like secondary domains absorb atmospheric moisture that can shift elongation values under ASTM D638. Orientation places snap arms in the XY plane because PolyJet digital materials exhibit lower Z-axis tensile retention at layer interfaces; Z-direction strain at break is heavily dependent on the number of exposed layer boundaries. Functional testing follows automotive connector validation practices including thermal cycling per SAE J1455 and electrical continuity checks under vibration, though chemical immersion in hot engine oil is not assumed without coupon testing to ASTM D471. The terminal parts are mass airflow sensor housings, transmission connector alignment plates, coolant level sender caps, and turbocharger actuator test brackets used in pre-production engine builds.
Vapour-phase soldering pallets are immersed in perfluoropolyether vapour at 230–240 °C for 60–120 s, which immediately disqualifies continuous load-bearing pallet surfaces made from RGD525 because the published heat deflection temperature of 63–65 °C at 0.45 MPa is below the process temperature by a wide margin. The role of this material combination is therefore confined to room-temperature fit validation of component pockets, clamp jaw geometry, and PCB locating features before production pallets are machined from PPS, GF-PEEK, or ceramic-filled composites. The FLX930 secondary phase is deliberately restricted to edge bumpers and component contact pads where local deformation is acceptable, while the RGD525 primary phase forms the rigid inspection body. Printed pallet prototypes are built with 5.0 mm solid walls, no Z-sectional bolted joints, and no through-thickness holes smaller than 1.0 mm because residual stress around small apertures leads to radial cracking during pallet handling. A low-temperature stress-relief step at 50 °C for 2 h is used before drilling dowel holes, since true annealing is not possible for this uncrosslinked photopolymer system. Dimensional flatness is measured on a granite table before any thermal cycling, and repeated exposure to dry heat is limited to 70 °C for inspection-level pallet conditioning. Published data for thermal equilibrium behaviour of this exact RGD525/FLX930 digital ratio in pallet-scale geometries is limited; users must measure thermal expansion according to ISO 11359-2 before committing to pocket tolerances below 0.2 mm.
| Standard / reference | Parameter or condition | Applicability outcome for RGD525/FLX930 |
|---|---|---|
| ASTM D648 | HDT at 0.45 MPa | Useful only below 63–65 °C; vapour-phase process temperature exceeds limit |
| IPC-7530 | Solder pallet temperature profiling | Material not suitable for production pallets; prototype fitment only |
| ISO 11359-2 | Coefficient of thermal expansion measurement | Required for pocket dimensional acceptance before machining final tooling |
| ASTM D638 | Tensile properties of rigid phase at 23 °C | Useful for mechanical handling stress, not soldering-process thermal stress |
The printed vapour-phase pallet prototypes are used for SMT line layout validation, conveyor clearance checks, and fixture duplication before the release of machined production pallets. The RGD525 primary body supports hold-down clamps and board registration edges, but all surfaces exposed to the actual vapour zone are treated as consumable and must not enter the production thermal cycle. Component pockets are inspected for undercuts and draft mismatch, then translated into final pallet designs in chemically resistant thermoplastics. The FLX930 pads at contact surfaces reduce scuffing of pre-soldered PCBs during fitment trials. In this application the material system is an engineering prototype medium, not a production soldering pallet material, and failure at the vapour-phase process temperature is an explicit boundary condition rather than an undocumented risk.
Handheld metering instrument enclosures with cantilever snap-beams are built with RGD525 as the rigid shell and FLX930-rich voxel zones at the beam root and engagement face. The digital material strategy addresses brittle root fracture typical of unfilled rigid photopolymers under repeated assembly, because the secondary elastomeric phase lowers strain concentration at the root radius. Published datasheet values for RGD525 typically cite tensile strength of 70–80 MPa and elongation at break of 10–15% under ASTM D638, while FLX930 typically shows elongation of 170–220% and tensile strength of 0.8–1.5 MPa under ASTM D412. The blended digital preset sacrifices monotonic tensile strength but improves absorbed energy in snap-fit cycling, though the specific blend Izod impact per ASTM D256 must be characterised for each build orientation because published data for all discrete hardness presets is limited. Shell sections are printed at 3.0 mm with solid infill around screw bosses and 0.5 mm fillets at the snap root. Build orientation places the snap arm in the XY plane so that the layer interface is not perpendicular to bending stress. Thread-cutting screws are replaced with heat-stake posts because screw engagement cracks propagate through layer boundaries in low-elongation rigid regions. Inserts are installed with ultrasonic insertion after drilling pilot holes with 0.15 mm radial clearance and slightly undersized counterbores. Electrical enclosure acceptance follows IEC 61010-1 for test equipment, but the printed polymer housing is not relied upon as a primary electrical insulation barrier. Flammability classification under UL 94 for the combined digital material is thickness-dependent; burn testing at the final wall thickness is required because published UL ratings for the separate primary and secondary components do not automatically apply to the blended geometry. Terminal parts are portable ultrasonic flow meter housings, gas detector shells, energy meter covers, and handheld analyser bodies where full production moulds are not yet released.
Medical device development groups use the RGD525/FLX930 combination for benchtop surgical instrument housings and surgical navigation tool mockups where no tissue contact or terminal sterilisation is required. The material system has no manufacturer medical grade certification under ISO 10993-1; cytotoxicity screening per ISO 10993-5 and irritation testing per ISO 10993-23 must be completed if the part moves into patient-contact or sterile-field use. The RGD525 primary phase provides dimensional accuracy for fit checks against mating instrument components, while the FLX930 secondary phase is applied only to grip pads and removable cable strain-relief boots. Autoclave exposure at 134 °C is outside the thermal capability of this polymer system and causes permanent warpage; therefore only non-sterile visualisation models are assigned to this material. Cleaning is limited to 70% isopropanol wipe disinfection and mild detergent, with no ultrasonic bath immersion because cavitation erodes soft FLX930-rich surfaces. Printed shells are generated from CT-derived DICOM data with a 0.5 mm exterior shell and no internal support below 0.4 mm in ribbed areas. Surgical guide manufacture is explicitly excluded because FDA-cleared surgical guides require dedicated biocompatible photopolymer resins and process validation under 21 CFR 820.30 design controls. The RGD525/FLX930 builds serve as design review models, instrument handle dimensional prototypes, endoscope control body shells, and simulator housing fixtures. Verification records for these mockups distinguish between form-fit prototypes and finished device materials, preventing transfer of unvalidated printed parts into production documentation.
In cabin interior bracket and loom clip dimensional mockups, the FLX930 secondary phase is localised to cable-contact surfaces while RGD525 forms the rigid body and attachment features. The combination permits undercut geometries that would require side actions in injection moulding, but it does not confer airworthiness flammability compliance. Uncoated RGD525/FLX930 parts are not rated for 14 CFR 25.853 aircraft cabin burn testing and are restricted to ground-based mockups, jig fixtures, and development-level fit checks. The digital material ratio is biased toward the rigid phase for structural features, while softer cable-contact pads keep wire insulation stable during repeated assembly. Printed clip arms with 1.2 mm beam width show acceptable deflection when oriented with the beam axis parallel to the X-axis; sections below 0.8 mm are thickened because support erosion and layer delamination become dominant. Attachment bosses are printed solid for insert installation, and the insert holes are reamed to achieve 0.05 mm radial clearance before heat-stake insertion. Chemical inventory records for these prototype parts are maintained under REACH Article 33 obligations, and the photopolymer components are screened against the RoHS 2011/65/EU restricted substances list at the supplier level. The terminal outputs are IFE bracket fitment dummies, seat harness routing clips, cabin air vent grille prototypes, and maintenance access panel mockups used before certified cabin materials are selected.
RGD525 primary phase is used for female vacuum-forming insert cavity surfaces when process temperatures remain below the published HDT limit. The FLX930 secondary phase adds impact resilience at flange edges during sheet loading and clamp impact, reducing chipping at the insert perimeter that occurs with fully rigid photopolymer tools. The tool set is produced as a modular base with an insert shell wall thickness of 8 mm and vacuum channel diameter of 1.0 mm; hole alignment is taken from the CAD model and post-drilled rather than printed at full depth to prevent void collapse. Thermomechanical stability is verified by flatwise HDT under ISO 75-2, not by repeated exposure above the published service limit. Low-temperature forming of thin-gauge PVC, EVA, and PE foam sheet is acceptable only when sheet preheat remains below 60 °C. The tool insert surface is sealed with epoxy after support removal, then coated with mould release because no release agent is incorporated into the photopolymer matrix. Printed inserts withstand a limited number of low-temperature forming cycles; published cycle-life data for this specific RGD525/FLX930 configuration is limited, and the tool is used primarily for formability studies, draw-ratio checks, and prototype blister geometry development. Draw-ratio evaluations follow standard sheet-thinning measurement practice rather than production tool durability testing. The terminal outputs are blister pack trial inserts, EVA case liner tools, packaging tray development fixtures, and temporary vacuum fixture cores for low-temperature pad printing checks. The boundary condition is clear: the material system replaces machined aluminium only when the process remains under 60 °C and when the expected cycle count is low enough that thermal creep does not alter cavity dimensions over the validation run.

Stratasys Rigur is an opaque rigid PolyJet 3D printing polymer combination supplied as a digital material comprising primary HIGH TEMPERATURE RGD525 and secondary TANGOPLUS FLX930. The two base resins are jetted from separate printheads and photopolymerized in situ, producing a solid with glassy RGD525 networks and dispersed elastomeric FLX930 domains. Build preparation specifies the material under the model name Rigur Rigid Opaque; the software-controlled blend ratio is fixed, so end users do not vary the composition. On PolyJet platforms such as Stratasys Connex3, J750, J835, and J850, the two resins are heated in separate reservoirs, jetted through piezoelectric nozzles, and cured by ultraviolet lamps. The process supports layer thicknesses of 16 µm in high-quality mode and 30 µm in high-speed mode. Because PolyJet construction is solid and does not use infill patterns, the mechanical response is more uniform within a layer than filament-based processes; however, the z-axis remains the weaker direction.
Manufacturer-published data for the RGD525/FLX930 combination report tensile strength of 45–50 MPa under ASTM D638-14, elongation at break of 15–20%, flexural strength of 60–70 MPa under ASTM D790-17, flexural modulus of 1700–2100 MPa, notched Izod impact of 40–50 J/m under ASTM D256-10, and Shore D hardness of 78–82 under ASTM D2240-15. Heat deflection temperature is reported at 52–55 °C under 0.45 MPa and 46–49 °C under 1.82 MPa according to ASTM D648-18. These values position Rigur between the high stiffness of pure RGD525 and the high elongation of TangoPlus FLX930. The addition of FLX930 reduces notched-impact brittleness of RGD525 while sacrificing part of its tensile strength and thermal deflection limit.
RGD525 alone is a high-temperature rigid photopolymer with tensile strength in the 70–80 MPa range and elongation at break near 10–15%; TangoPlus FLX930 is an elastomer with Shore A hardness of 26–28 and elongation above 170–220%. Jetting the two resins as a digital material creates a hard-soft matrix in which the RGD525 phase supplies rigidity and thermal resistance while the FLX930 phase interrupts crack propagation under load. The result is a notched Izod impact of 40–50 J/m, roughly two to three times higher than that of RGD525. The trade-off is a lower heat deflection temperature: the elastomeric domains begin to soften at temperatures lower than the pure high-temperature phase can withstand. In practice, this specifies the material for functional prototypes requiring snap-fit insertion, threaded fastener retention, or moderate impact exposure rather than for components that must maintain close dimensional tolerances above 55 °C under continuous load.

The comparative data in the table are typical values from manufacturer literature and are sensitive to print mode, orientation, and build position. The values should not be used for final design without testing on a build coupon produced under the intended print orientation and layer thickness.
Under ASTM D648-18, the heat deflection temperature is measured by applying a flexural stress of 0.45 MPa or 1.82 MPa to a rectangular specimen immersed in a bath heated at 2 °C/min; the reported temperature corresponds to a deflection of 0.25 mm. For Rigur, the 0.45 MPa value of 52–55 °C is the more relevant design limit for lightly loaded housings and guides. The 1.82 MPa value of 46–49 °C is a more conservative threshold for loaded structural parts. The tensile properties measured under ASTM D638-14 are orientation-dependent; printed specimens typically show lower elongation in the z-axis because interlayer adhesion is governed by the degree of conversion at the layer interface. The modulus values in the 1700–2100 MPa range are roughly one-half to two-thirds of typical injection-molded polypropylene homopolymer, which is why Rigur is often selected as a form-fit surrogate for polypropylene assemblies rather than as a replacement for high-stiffness acetal or glass-filled nylon components.
The selection of a continuous-use temperature must also account for creep, not only heat deflection temperature. HDT is a single-point deflection test, not a long-term creep limit. For load-bearing applications, ISO 899-1:2003 or ASTM D2990-17 creep data should be generated because photopolymers exhibit time-dependent strain under sustained stress. Published data for Rigur-specific creep is limited, so a validation program is required before using the material in chronically stressed designs.
Build orientation is the dominant process variable controlling fracture behavior in Rigur components. Parts printed with the primary tensile axis lying in the x-y plane show tensile strength near the upper end of the 45–50 MPa band; parts printed flat with tensile loads along the z-axis may show reductions in tensile strength of 10–20% relative to the in-plane value because of weaker interlayer crosslinking. For thin-walled snap-fit features, the hinge line should be oriented parallel to the y-axis rather than across the z-axis; this orientation reduces delamination during repeated flexure. Support removal from blind recesses and fine pitch gaps is a known production bottleneck: water-jet cleaning does not reliably clear support from enclosed channels with cross-sections below 1 mm, and manual pin removal is required. Overly aggressive water-jet pressure can de-bond thin shell features, so shielded areas should be supported with breakaway support rather than soluble support where the geometry permits. Machining operations on Rigur are performed with carbide tooling and low cutting force to avoid thermal softening.
Moisture absorbed during water-jet cleaning can alter Shore D readings and small dimensions; parts should be conditioned for 24 h at 23 ± 2 °C and 50 ± 10 % relative humidity before dimensional inspection. Critical mechanical properties are verified on a build coupon printed in the same orientation as production parts rather than by relying solely on supplier data. Batch-to-batch variance is not fully eliminated by the PolyJet process and is typically assessed by destructive tensile testing under ASTM D638-14.
Unopened material cartridges should be stored at 15–25 °C and protected from light. Before printing, material cartridges are loaded into the designated printhead slots; RGD525 and FLX930 require separate slots. Solvent introduction into the material pathway is not permitted because the acrylate-based resins can cross-contaminate and shift the final digital material properties.
Rigur is specified for short-run functional validation where a part must survive multiple assembly cycles without the brittle failure observed in unfilled Vero-class materials. Snap-fit covers, living-hinge battery door prototypes, and wire-routing clips are typical applications because the material deforms under insertion and returns to shape without cracking. The notched Izod value of 40–50 J/m under ASTM D256-10 is higher than that of VeroWhite and provides a margin for impact-loaded features. For thermally demanding applications, Rigur is not equivalent to Digital ABS; Digital ABS retains higher heat deflection temperature and is preferred for parts exposed to temperatures above 55 °C. In contrast, Rigur is preferred over Digital ABS for parts with thin living hinges or snap-fit arms that require higher flexural fatigue tolerance. For silicone casting tooling and low-pressure mold inserts, the opaque surface and machinability of Rigur permit direct cavity finishing, but the working temperature must remain below the 52–55 °C heat deflection threshold, and published data for this specific configuration is limited.
| Requirement | Relevant standard | Rigur response | Alternative PolyJet material if Rigur is out of range |
|---|---|---|---|
| Continuous service above 55 °C | HDT ASTM D648-18 at 0.45 MPa | not recommended | Digital ABS or RGD525 |
| Repeated snap-fit insertion | ASTM D638-14 elongation | 15–20%; conservative strain limit below 7.5–10% | TangoPlus FLX930 for extreme flexure |
| Chemical immersion in ketones | ASTM D543-21 | swelling and hardness reduction possible | VeroClear or VeroUltra may require testing |
In functional prototype programs, Rigur is evaluated for assembly force and retention force using a universal testing machine with a 50 N load cell; published data for this specific configuration is limited. The material is also used for form-fit fixtures where a rigid, non-marring contact surface is required. The key limitation is thermal: exposure to engine-compartment air above 55 °C under load leads to creep and dimensional relaxation. The material should not be chosen for continuous immersion in hot water above 50 °C or for prolonged contact with ketone-based cleaning solvents; these fluids can swell the elastomeric domains and reduce hardness. When chemical compatibility is uncertain, a 24 h immersion test under ASTM D543-21 is used before committing to production design.
