In consumer electronics accessory overmoulding trials, the RCL-ENT-D65 multi-material set is built as two discrete resin volumes: VisiJet CR-CL 200 supplies the clear rigid shell, bezel, and snap-fit retention features, while VisiJet CE-NT is deposited at the peripheral gasket lip, button-return region, and corner impact interfaces. The MJP 2500 Plus build processor places material droplets in a voxel matrix rather than volumetrically mixing the two resins in a pre-printing reservoir, so the Shore D 65 designation is a digital-material hardness outcome, not a batch-mixed formulation ratio. The commercial supplier does not publish the exact dithering ratio between CR-CL 200 and CE-NT at the transition layer. Support wax is removed at the lower-temperature melt-out setting specified in the printer’s material handling document; the gasket channel is then air-jet cleaned to prevent wax entrapment. The rigid shell is measured according to ASTM D638-14 using Type V specimens when a flat zone can be cut from the build; the elastomer zones are checked with a Type D durometer under ASTM D2240-15 using a 15 s delay reading. EU-bound prototypes require substance declarations covering EU 2011/65/EU RoHS and REACH candidate-list contaminants, but documentation must be requested from the material supplier because photopolymer additive packages can shift by production lot. Terminal products in this segment are functional enclosure prototypes with integrated soft gaskets, produced in batches below 100 units. Published data on long-term UV yellowing of the CR-CL 200 shell in this specific composite remain limited; if outdoor evaluation is planned, accelerated weathering follows ASTM G154-16.
For hospital training-lab models that combine rigid bone-analogue surfaces with soft ligament and periosteal structures, RCL-ENT-D65 is prepared as a single multi-material build. The mandible, maxilla, or rib segments are printed in VisiJet CR-CL 200 at full rigid material density, while interosseous ligament and cartilage-like surfaces are assigned VisiJet CE-NT. The build processor can produce a graduated hardness zone at the insertion area by spatially varying the digital material composition between the two base resins; the supplier does not disclose the exact dithering pattern. The soft-tissue analogue is not intended for invasive patient contact and is not supplied as implant-grade photopolymer. When a training model enters a clinical environment, the finished part is assessed under ISO 10993-1:2018 for skin-contact duration and extraction risk, but a favorable result must be validated per batch because post-cure conditions and support residues influence biological response. Support wax removal requires the low-temperature melt-out sequence, as the elastomeric CE-NT regions can distort if the bath is run at the higher wax-only protocol. Thin soft-tissue walls below 0.8 mm may tear during support removal if they are undercut. The terminal product is a procedure-planning model or surgical teaching aid, not a regulatory-cleared implant. Production-scale experience indicates that vertical build orientation improves bone-surface detail but increases support consumption in soft-tissue undercuts; the build plane is typically split to reduce post-processing damage. Dimensional tolerance of the rigid bone analogue is monitored against the STL model using a tolerance band of ± 0.1 mm in critical anatomical landmarks, though published data for this specific composite in anatomical printing are limited.
Microfluidic and pneumatic manifold prototypes assign VisiJet CR-CL 200 to the channel body, barb fittings, and threaded ports, while VisiJet CE-NT forms the diaphragm, check-valve lip, or cap-seal face. The multi-material transition is placed at the diaphragm root; the CAD model maintains a minimum rigid wall of 1.0 mm around the elastomer insert to prevent tear propagation during repeated pressure cycling. Support removal for internal channels requires a two-stage process: the sacrificial wax is melted from the fluid path, then a mild solvent rinse is passed through the printed channel. The solvent selection must remain within the chemical resistance envelope of the CE-NT diaphragm; published data for this composite in aggressive solvents are limited, so bench immersion trials are performed with the specific fluid according to ASTM D471-16. Elastomer tensile and elongation are measured with ASTM D412-16 using die-cut specimens taken from a flat overflow coupon on the build plate. The Shore D 65 target at the diaphragm root is checked with ASTM D2240-15; if the measured value falls below Shore D 60 after support removal, the digital-material calibration in the build processor is adjusted before production. Terminal devices are pneumatic manifold prototypes used to validate valve sequencing and seal compression before committing to a silicone injection mould. The rigid channels are transparent enough for flow-visualization inspection after polishing; crack initiation at the rigid-elastomer interface is monitored under a binocular microscope at 5× magnification during burst-pressure trials, but no published burst-pressure rating is available for this specific material combination.
In end-of-arm tooling for collaborative robot systems, RCL-ENT-D65 is used to print gripper jaws with rigid VisiJet CR-CL 200 mounting flanges and VisiJet CE-NT contact pads. The elastomeric contact face protects polished workpiece surfaces from scoring; the rigid flange carries the pneumatically actuated jaw body. The primary operational limit is the interfacial peel resistance between the two photopolymer phases. When the gripper pad is loaded in shear, the rigid flange-to-elastomer interface behaves as a bonded joint, but during lateral release, peel forces concentrate at the pad edge. Interfacial adhesion is therefore tested according to ASTM D903-98 using a flexible-to-rigid T-peel configuration; the measured peel strength of the printed digital interface is often lower than the cohesive strength of either base resin, but exact values for RCL-ENT-D65 are not published in supplier literature. On the production floor, pad geometry is modified to increase mechanical interlocking: dovetail grooves in the CR-CL 200 flange at a 90° included angle force the CE-NT pad into compression rather than pure shear. Build orientation places the interface plane parallel to the print bed to avoid z-axis layer weaknesses. Support removal for air channels in the gripper is completed with the low-temperature wax melt-out, then the part is blown dry at 0.6 MPa pneumatic pressure to clear fine orifices. Terminal products are robot gripper jaw sets used on collaborative robot arms with integrated pneumatic feeds. Functional validation includes 10,000 open-close cycles with a rated workpiece mass not exceeding the gripper payload; creep of the CE-NT pad is measured at 23 °C ± 2 °C under ASTM D2990-17. The main limit in automated handling trials is the gradual compression set of the elastomer pad after sustained clamping; if the jaw is stored in the closed position for more than 72 h, the set-recovery time increases. Published data for this specific composite in automated handling applications remain limited.
Automotive sealing prototypes use VisiJet CR-CL 200 for bolt-bearing flanges and alignment ribs, with VisiJet CE-NT forming the sealing bead. The printed gasket is not intended for high-temperature engine applications; it is used to validate seal-compression profiles and bolt-force distribution before transfer to elastomer compound tooling. Compression set is the critical material property for this segment. The test specimen is prepared from a flat gasket coupon and measured according to ASTM D395-18, Method B, at 25% constant deflection and 23 °C ± 2 °C. The D65 digital material may exhibit higher compression set than a moulded thermoset rubber because the CE-NT phase is a UV-crosslinked elastomer with viscoelastic recovery. The processing window for the printed sealing bead is narrow: the bead height is controlled in the CAD model and the build processor assigns the elastomer volume only to the bead cross-section, avoiding elastomer bleed into the rigid flange. Support wax is removed at the lower-temperature protocol; high-temperature oven drying is not used because it can accelerate compression set in the CE-NT bead. Terminal products are low-pressure fluid-sealing prototypes used on HVAC flanges and wire-harness grommets. The automotive validation workflow includes leakage testing with a differential-pressure decay instrument; the gasket is compressed to a defined bead deflection and held for 60 s, then the pressure decay is compared with the tolerance band derived from the production EPDM gasket. No published long-term automotive fluid resistance data are available for RCL-ENT-D65; immersion testing is performed according to ASTM D471-16 in the target proprietary coolant. The D65 interface between rigid and elastomer phases must be located at least 1.5 mm from the sealing contact line to avoid a hard spot that creates local leakage.
Wearable product prototyping programs assign the VisiJet CR-CL 200 transparent shell to the rigid sensor housing and the VisiJet CE-NT phase to the strap hinge, skin-contact pad, or button membrane. The single-build multi-material print allows the optical clarity of the rigid housing to be retained while the elastomer absorbs flexure at the strap attachment. Build orientation places the clear housing face downward with the elastomer strap printed as an upward continuation; this orientation generates a visible textural boundary at the transition, but it preserves the optical face quality. The elastomer phase is printed with a layer resolution controlled by the MJP 2500 Plus material parameter set; thicker layers increase build speed but degrade the memory of the strap folds. Support wax removal for the hollow housing uses the low-temperature melt-out and an ultrasonic bath cycle; ultrasonic energy is kept below the supplier-recommended threshold for CE-NT to prevent cavitation erosion at the elastomer surface. Skin-contact compliance for the CE-NT pad is not assumed; when the prototype is used in extended wear studies, dermal irritation is assessed under the sponsor’s own protocol following the principles of ISO 10993-10:2010, but the resin is not marketed as a certified biocompatible elastomer. Mechanical validation uses ASTM D790-17 for the rigid shell flexural modulus and ASTM D412-16 for the strap elastomer tensile set. The terminal product is a functional wearable sensor prototype employed in short-duration human-factors tests and in wireless-connectivity validation. Published data for dynamic fatigue of the CE-NT strap under repetitive wrist motion are limited; hinge failures in field trials typically occur at the rigid-to-elastomer boundary if the strap thickness is below 1.2 mm.

The product designated 3D Systems VisiJet RCL-ENT-D65 Multi-Material Composites (VisiJet CR-CL 200** + VisiJet CE-NT) is a two-feedstock photopolymer build mode for 3D Systems MultiJet Printing platforms rather than a single homogenized resin. The material set is configured for dual-material co-deposition on the ProJet MJP 2500 Plus or equivalent MultiJet Printing platform with dual-cartridge capability. In this configuration, the rigid transparent phase VisiJet CR-CL 200** and the elastomeric natural phase VisiJet CE-NT are jetted in a fixed spatial ratio to produce a composite with a target Shore D hardness of 65 under ASTM D2240-15. The D65 designation is the primary material identity; it separates the composite from single-phase CR-CL 200**, which is specified at Shore D 80, and from single-phase CE-NT, which is specified in the Shore A 27 range. The result is an intermediate stiffness material in which the rigid phase contributes tensile modulus in the 1,500 MPa to 2,000 MPa range when measured according to ASTM D638-14, while the elastomer phase contributes elongation and energy-dissipating behavior. Published data for the fully blended RCL-ENT-D65 configuration is less extensive than for the two base materials, so tensile and flexural values should be checked against the current manufacturer’s datasheet for the specific printer mode and layer thickness.
The composite is formed at the printhead through sub-picoliter droplet deposition and subsequent UV curing, not through bulk compounding or twin-screw extrusion. Inkjet droplet placement interleaves the two materials according to a fixed coordinate map; after each layer is deposited, planarization and UV exposure lock the phase arrangement before the next layer is applied. Because CR-CL 200** and CE-NT differ in crosslink density after cure, the resulting solid contains discrete low-crosslink elastomeric domains distributed within a higher-crosslink rigid matrix. This spatial arrangement modifies crack propagation and impact energy distribution compared with either base material alone. Viscosity, surface tension, and cured film response are controlled within the manufacturer’s printhead qualification windows. The process does not create a molecularly homogeneous alloy; therefore, material data derived from bulk-mixed liquid resin would not represent the jetted component. Build orientation, layer thickness, and the ratio map all influence the final mechanical properties. For acceptance testing, tensile bars should be prepared in both flat and vertical orientations and tested according to ISO 527-2:2012 or ASTM D638-14, because photopolymer composites exhibit anisotropic behavior along the z-axis. Flexural specimens should be tested according to ISO 178:2019 or ASTM D790-17. These tests are used not to redefine the product but to establish process capability windows for a given production line.
Table 1 establishes the standard methods applicable to the composite and its base materials. The listing is not a substitute for full mechanical characterization, because the composite is defined through a Shore D65 target rather than a single tensile or flexural data point. Tensile and flexural data from the two base materials cannot be linearly mixed to predict composite response; the photopolymer architecture, interpenetration at phase boundaries, and UV cure dose affect load transfer between domains.

Incoming quality control should record material lot numbers, printer serial number, layer thickness, and ambient dew point for each build because the composite is generated at the voxel level and hardness may vary with machine state. Retaining a test coupon for tensile and hardness verification is recommended where the build is used as a master pattern or assembly fixture.
Single-phase VisiJet CR-CL 200** is an optically clear rigid photopolymer with a Shore D 80 durometer. Its datasheet tensile modulus is commonly cited near 1,860 MPa under ASTM D638-14, with elongation at break in the 10–15% range. Single-phase VisiJet CE-NT is a low-durometer elastomer published at Shore A 27 under ASTM D2240-15 and elongation at break near 200% under ASTM D638-14. The RCL-ENT-D65 composite occupies an intermediate position: the Shore D65 hardness indicates a macro-hardness closer to a semi-rigid thermoplastic than to a rubber, while the CE-NT phase provides strain accommodation that is absent in a monolithic high-modulus rigid network. Compared with a rigid single-phase build, the composite generally reduces brittle failure in thin-section snap-fit features; compared with pure CE-NT, it increases structural stiffness and reduces large-strain deformation. The comparison is not equivalent to a plasticized or impact-modified random copolymer because the elastomer phase is spatially discrete. Optical clarity is sacrificed relative to CR-CL 200**; the composite should not be specified for visible light transmission unless ASTM D1003 haze and transmittance data are available for the specific layer stack.
For functional prototypes and short-run fixtures that require snap-fit engagement, tactile grip surfaces, or repeated assembly and disassembly, the RCL-ENT-D65 build is selected where a rigid photopolymer would exceed its elongation limit and a pure elastomer would fail to maintain dimensional location. Applications should be evaluated with ISO 527-2:2012 tensile tests using specimen geometries matched to the minimum wall section. Thermal exposure should be assessed with ASTM D648-18 at 0.455 MPa rather than assuming service performance from Shore hardness alone. Parts produced in this composite have been used for assembly fixtures, enclosure prototypes with integrated snap features, and overmolded-like ergonomic tooling; however, published data for some of these application categories is limited. No long-term skin-contact or food-contact designation should be inferred unless the current 3D Systems regulatory datasheet explicitly lists the relevant certification. Chemical exposure in the end-use environment should be screened according to ASTM D543-21 before field deployment.
Strain-rate dependence must be characterized when the printed part is used as a snap-fit or living-hinge substitute. Photopolymer networks do not exhibit the same yielding and craze behavior as injection-molded polypropylene or ABS, and the D65 hardness does not predict retention force after repeated flexural cycling. Cyclic tests should follow the repeated loading provisions of ISO 527-2:2012 or flexural fatigue methods such as ASTM D7774-17. Build orientation is a control variable: a snap beam printed horizontally, vertically, and on-edge will exhibit different peak force and permanent set. Production-scale MultiJet builds have shown z-axis interlaminar surfaces as the dominant source of variability in recovery, so acceptance testing should include samples from multiple locations in the build envelope. If the intended use includes continuous strain above 2% to 5%, permanent set should be measured after a fixed number of cycles rather than inferred from single-pull elongation. The current datasheet for the composite may not include fatigue curves; published data for this specific configuration is limited, so prototype validation remains necessary for load-bearing designs.
During production-scale operation, jetting stability and final durometer are influenced by ambient humidity, printhead idle time, and material lot viscosity within manufacturer release windows. Support removal for MJP builds follows the platform-specific workflow, typically involving the dedicated support material and elevated-temperature aqueous bath processing; actual temperature and duration are specified by the printer and support material documentation. After support removal and cleaning, parts should be conditioned according to ASTM D618-21 or ISO 291:2008 before dimensional or mechanical verification. Surface hardness should be measured at 23 °C ± 2 °C and 50% ± 10% relative humidity unless otherwise specified by the test method. Batch-to-batch variation in CR-CL 200** and CE-NT base stocks can shift the final composite durometer by a few points within the D65 nominal class; process capability studies should therefore use a hardness range of ±2 Shore units rather than a single-point acceptance criterion. If the machine has experienced nozzle dropout or mixed-lot cartridges, the hardness map may vary across the build volume, and parts from suspect builds should be sampled by test coupon rather than by production part inference alone.
The composite is a thermoset photopolymer network and should not be treated as a thermoplastic for tolerance stack analysis. Dimensional checks should be made after conditioning and after any post-cure or support-removal heating. Thermal deflection is evaluated under ASTM D648-18 with a 0.455 MPa applied stress; typical photopolymer networks of this class show deflection temperatures below those of semicrystalline engineering thermoplastics. Creep and stress relaxation data for RCL-ENT-D65 are limited; long-term load-bearing components should be tested under the intended static load using ISO 899-2 creep or the applicable stress-relaxation method. The build process can produce anisotropic shrinkage, with the z-axis generally showing greater variability than the xy-plane. For close-tolerance assemblies, the production process window should be established by printing a multi-orientation qualification coupon set and measuring critical-to-function dimensions with a calibrated optical or contact metrology system. Tighter tolerances may require secondary machining, but the composite may not machine in the same manner as a homogeneous polymer because the elastomer domains can heat and smear under aggressive tool speeds. Published data for this specific configuration is limited; machining parameters should be validated on scrap parts.
Compared with other multi-material jetting systems that use shore-based digital rubber blends, the RCL-ENT-D65 composite is limited to the two specified base materials; it does not provide an open parameter set for arbitrary Shore gradients in a single build unless the platform is specifically configured for variable ratio mapping. Users coming from single-cartridge VisiJet MJP workflows should note that the D65 composite consumes both material positions and may require separate support material channels, reducing available build capacity for multi-material part flanks. The material is not a direct substitute for room-temperature vulcanizing silicone or cast polyurethane, because recovery, tear resistance, and compression set differ under ASTM D624 and ASTM D395 testing. Regulatory compliance must be verified against the current Safety Data Sheet and 3D Systems material certification. General statements about RoHS, REACH, or Proposition 65 cannot be assumed from the product name. The product designation should not be interpreted as an anatomical or medical claim; material suitability for anatomical models is determined by downstream sterilization and tissue-contact requirements. If electrical insulation certification or flame resistance is required, the relevant IEC 60112 and UL 94 tests must be run on the final thickness and orientation used in the field. The presence of uncured monomer residuals after post-processing may affect surface tack and chemical resistance; inert gas or oven post-cure procedures should follow the manufacturer’s documented instruction. Published data for this specific configuration is limited for long-term UV weathering, so outdoor service requires ASTM G154 or ISO 4892-2 screening.
