In the shell investment casting route for low-pressure turbine components, the CR-WT 200 fraction is assigned to the sacrificial pattern volume at 100% of the build head flow, while the CR-BK fraction is excluded from the castable geometry because its pigment package is not specified for burnout below 750°C. Pattern dimensions are controlled to ISO 8062-3:2023 for rough casting geometric tolerances, and as-built surface texture is checked against ASME B46.1-2019 before shell coating. Processors running MJP platforms with 32 µm layer thickness print the pattern, then remove support wax in a convection oven held at 35–40°C, which is below the observed deformation threshold of 45°C for thin trailing edges measuring 0.6 mm or less. The pattern is assembled onto a wax tree with 2–4° sprue convergence angles, coated with colloidal silica slurry to a shell thickness of 7–10 mm, and dewaxed in an autoclave at 150–165°C and 0.55–0.7 MPa before firing at 650–750°C to remove residual ash below 0.05 wt%. No external wax powder or reactive diluent is compounded into the castable fraction; addition of release agents above 0.5 wt% on the pattern surface has been shown on production lines to alter primary slurry adhesion and increase shell face coat porosity. Terminal components produced through this route include equiaxed nickel superalloy impellers, turbine stator segments, and fuel pump housings.
In dental and high-volume jewelry flask casting, flask cracking is initiated when the burnout ramp crosses 730°C while the sacrificial CR-WT 200 phase leaves ash residue exceeding 0.05 wt%. Final casting alloys are assessed under ISO 22674:2022 for dental metallic restorations, and skin-contact jewelry pieces are screened for nickel release under REACH Annex XVII entry 27; the castable pattern itself is not a finished device but must be selected from lot-controlled cartridges to keep ash variability within the required range. The formulation addition in this process uses CR-WT 200 at 100% by volume; the CR-BK fraction is not blended into the castable pattern because its higher pigment retention widens ash scatter across burnout cycles. The support-to-build volumetric ratio is set at 1.2:1 for high-density tree assemblies, and the pattern is printed at 32 µm layer thickness before support wax is removed at 35–40°C. Sprues are wax-welded at 2–3° convergence angles to prevent air entrapment during phosphate-bonded investment. Burnout is executed with a ramp of 2°C/min from 300°C to 730°C, followed by a hold of 1.5–3 h depending on flask diameter; production batches with flask diameters above 100 mm show thermal gradient cracking unless the hold time is extended because the outer investment expands before the inner core reaches uniform temperature. Centrifugal or vacuum casting machines then deliver molten alloy into the void left by the fully burned-out CR-WT 200. Terminal part types include molar crowns, three-unit bridge frameworks, and micro-set signet rings.

| Dental and jewelry flask casting | ISO 22674:2022, REACH Annex XVII entry 27 | Alloy mechanical evaluation; nickel release screening | Burnout hold 1.5–3 h at 730°C |

Electronics assembly fixtures printed from the CR-BK fraction require draft angles above 1.5° on tray cavities because ejection force rises rapidly below that threshold on production lines using ESD-safe workstations. Printed fixtures are assessed to ANSI/ESD S20.20-2021 and IEC 61340-5-1:2016; where surface resistivity must fall between 10^6 Ω/sq and 10^9 Ω/sq, processors apply a carbon-loaded coating after support removal, and the coating must be revalidated under ANSI/ESD STM11.11. The formulation ratio in this application uses CR-BK at 100% by volume for the load-bearing tray and CR-WT 200 at 15–25 vol% only where a non-marring pad is digitally bonded into the rigid nest; no solvent or external friction agent is added to the CR-BK phase because short-chain migration can shift surface resistivity after 72 h of ambient conditioning. The MJP process runs at 32 µm layer thickness, support wax is removed at 35–40°C, and cavity sidewalls are finished with abrasive vapor honing at 600 grit to reduce friction. Dimensional inspection over a 150 mm span is held to ±0.12 mm, and wall sections below 0.8 mm are avoided because observed bowing after support removal exceeds this tolerance. Terminal products include SMT stencil frames, PCB locating trays, and connector assembly nests.
When the print scheduler targets a Shore A 50 digital composite, the deformation field is partitioned between the CR-BK rigid phase and the CR-WT 200 elastomer phase, making interphase adhesion the controlling failure mode under repeated loading. Medical training models in this category are not patient-contacting and are not automatically subject to ISO 10993-1:2018; however, verification laboratories frequently require material contact evaluation under ISO 10993-5:2009 for cytotoxicity and ISO 10993-10:2021 for sensitization when the model enters clinical simulation environments. A starting digital ratio of 60% CR-BK / 40% CR-WT 200 by volume is used for cortical bone surrogate regions, while soft-tissue shells are printed at 100% CR-WT 200; exact ratios are adjusted against CT-derived Hounsfield data because published data for this specific configuration is limited. Multi-material jetting at 32 µm layer thickness is followed by support wax removal at 35°C, a 2 min ultrasonic isopropanol rinse, and forced-air drying at ambient temperature; autoclave sterilization at 134°C for 3 min must be validated because preliminary production evaluations observed interphase delamination after 50 cycles in some lots. Terminal products include orthopedic training femur models, vascular access manikins, and laparoscopic task trainers.
Interior automotive prototypes must satisfy flammability evaluation under FMVSS 302 or ISO 3795, and UV-stable surface validation is typically run under ISO 4892-2:2013 when the part is mounted near glazing. In this scenario the printed control knob uses a core-to-overmold volumetric ratio of 70% CR-BK / 30% CR-WT 200 by volume; the digital interlock is generated with micro-dovetail features having 0.2 mm engagement height and draft angles below 5° to prevent rotational slip. The MJP process runs at 32 µm layer thickness, support wax is removed at 35–40°C, and the sealing surface is wet-sanded with 600 grit before assembly. Thermal cycling from -40°C to 85°C for 100 cycles is applied to the assembled prototype, and torque retention above 0.02 N·m at the micro-dovetail interface is used as the acceptance criterion because production evaluations observed slipping below that value. Terminal products include climate control knobs, indicator bezels, and seat memory switch covers.
For vacuum casting master patterns, surface replication fidelity below 2 µm Ra becomes the controlling variable because silicone tooling reproduces stair-step artifacts and fracture lines at exactly the same scale. The master pattern is printed from CR-BK at 100% by volume; the CR-WT 200 fraction is held at 0% in the master because its elastomer phase can swell during polyurethane pouring and shift dimensional reference surfaces by more than 0.1 mm over 200 mm. Dimensional control follows DIN 16742:2013 for plastic moulded parts, and surface finish is specified as SPI A2 after progressive sanding from 400 grit to 1200 grit and application of a non-reactive clear coat. The printed master is processed at 16 µm or 32 µm layer thickness, support wax is removed at 35–40°C, and the master is placed in a vacuum chamber at 25–40°C for silicone tooling cure. Polyurethane cast parts are then produced under 0.08–0.1 MPa vacuum at 60–80°C; silicone degassing below 1.5 mbar is avoided because bubble nucleation at the master surface becomes difficult to eliminate. Terminal products include low-volume polyurethane bezels, gaskets, and functional shore-controlled prototypes.

3D Systems VisiJet RBK-RWT-L50 Multi-Material Composites is a paired build-material set for MultiJet Printing platforms, comprising two separate ultraviolet-curable rigid resins: VisiJet CR-BK black photopolymer and VisiJet CR-WT 200 white photopolymer. The kit designation does not denote a blended feedstock; the two resins are jetted from independent heated reservoirs and discrete piezoelectric printhead channels, then solidified by UV exposure in adjacent or interlocking voxel regions within one build envelope. This arrangement allows high-contrast black-and-white models, assembly study parts, inspection fixtures, and form-fit prototypes to be produced without secondary painting. The CR-WT 200 designation may carry a double-asterisk qualifier in regional product lists, indicating that firmware, regional availability, or machine configuration must be validated against the current 3D Systems compatibility matrix before uploading a job. Both resins are supplied in manufacturer-sealed cartridges and require a printer equipped with separate support-wax delivery. Single-channel platforms, aftermarket material kits, or machines loaded only with clear or castable feedstocks are not appropriate for this material pair.
The current 3D Systems datasheets for VisiJet CR-BK and VisiJet CR-WT 200 express tensile strength, tensile modulus, and elongation at break according to ASTM D638; flexural strength and flexural modulus according to ASTM D790; heat deflection temperature according to ASTM D648 at 0.455 MPa; and Shore D hardness according to ASTM D2240. Published representative property envelopes for this rigid photopolymer family typically place tensile modulus between 1.2 GPa and 1.8 GPa, tensile strength between 30 MPa and 45 MPa, and elongation at break between 8% and 20%. These figures are not guaranteed specification limits; orientation-dependent polymer anisotropy, post-cure duration, pigment dispersion, and laboratory conditioning can shift values by several percent. The black grade generally derives its opacity from a pigmented package that may alter cure depth and tensile modulus relative to the white grade. Exact current values must be taken from the current product datasheets, not from third-party summaries.
| Property | Test method | CR-BK envelope | CR-WT 200 envelope |
|---|---|---|---|
| Tensile strength | ASTM D638 | 30–45 MPa | 30–45 MPa |
| Tensile modulus | ASTM D638 | 1.2–1.8 GPa | 1.4–1.8 GPa |
| Elongation at break | ASTM D638 | 8–20% | 8–15% |
| Flexural strength | ASTM D790 | 50–65 MPa | 50–65 MPa |
| Heat deflection temperature | ASTM D648 at 0.455 MPa | 50–60 °C | 50–60 °C |
| Shore D hardness | ASTM D2240 | 78–82 | 78–82 |
Build orientation and part density matter more than nominal datasheet values in MJP. Tensile specimens harvested from vertical Z-axis builds often show reduced tensile strength compared to XY-plane builds because interlayer adhesion at typical MJP layer thicknesses of 32 µm or 16 µm, where ultra-high-resolution mode is available, remains the weakest plane. Datasheet coupons should be reproduced on the same printer, in the same orientation, and through the same support-wax removal cycle as the production part before accepting a design validation value.
Factory-sealed cartridges should be stored at 15–30 °C, away from UV and direct sunlight, and should not be frozen. If a cartridge is left on a heated printer dock beyond the manufacturer’s idle limit, viscosity drift can shift layer thickness and increase surface roughness. Return unused cartridges to sealed storage with the cap fully seated, because exposure to humid air can introduce moisture that causes interfacial adhesion loss in the next build. Open material should be consumed within the manufacturer’s specified pot life; users should not top off partially used cartridges with resin from another lot without documented compatibility.
When a single build contains both black and white regions, the process sequence begins with a pre-build warm-up and stirring cycle that reduces pigment settling in the black reservoir. The printer jets build material and a separate phase-change wax support from independent channels; black and white resin voxels are not mixed into a gray scale but are placed as discrete regions with a defined interface. The printed interface is a mechanical boundary, not a welded or interdiffused blend. Small gaps between color boundaries, insufficient edge clearance, or unsupported black islands inside white walls can leave wax-filled channels that must be cleaned thoroughly.
Support-wax removal is typically performed in an oven followed by ultrasonic cleaning; the oven setpoint must remain below the heat deflection temperature of the build material to prevent creep in thin walls. If the bath or oven exceeds 60 °C, localized distortion, surface tack, or support-wax reflow may occur. After wax removal, a UV post-cure step may be used to complete residual acrylate conversion; however, overexposure can yellow white surfaces or dull the black finish. Thin white walls below 1.0 mm may sag during wax oven cycles unless supported by ribs or oriented to minimize overhang.
The usable feature resolution and minimum wall thickness are governed by the printer’s layer slice and voxel placement, not by resin alone. Drilled or reamed holes below 0.8 mm diameter may close after support-wax removal because residual wax films remain in restricted bores; through-hole cleaning becomes unreliable at aspect ratios beyond 8:1. Black sections, because of pigment loading, may require slightly longer room-temperature rest after post-cure before dimensional inspection; residual conversion and thermal contraction are not instantaneous.
Abrasive finishing, tapping, and insert installation are possible if low cutting speeds and shallow passes are used. The black and white grades behave as brittle rigid resins, with low elongation and limited impact toughness compared to polycarbonate or ABS injection-molded parts. Solvent exposure should be assessed with the manufacturer’s chemical compatibility table; aggressive ketones, chlorinated solvents, and high-pH cleaners can degrade the acrylate network. Qualification for a production fixture or gauge should include small-batch tensile or flexural specimens printed in the intended orientation and measured according to ASTM D638 and ASTM D790, not only accepted from datasheet values.
On production floor equipment, cartridge conditioning errors and idle dwell time account for most start-of-day defects in this material set. Cartridges should be equilibrated to 18–28 °C before loading, and the machine’s reservoir stirring cycle should be run after extended idle periods to resuspend black pigment. Relative humidity above 70% during open cartridge handling can introduce water into the build material, increasing viscosity and producing streaks or voiding in the first layers. Operators commonly observe that black parts tolerate wax-oven air flow better than thin white walls because white resin may show thermal discoloration at closer proximity to heating elements.
Build trays should be cleaned of residual wax before stacking because wax carryover from one job to the next fills blind holes, microtext, and small alignment features in the next build. Two-material operation also creates a lot-control requirement: the black and white cartridges in a single RBK-RWT-L50 kit are not mechanically interchangeable with single-material consumables and should be installed only in designated channels. Mixing same-color resins from different lot numbers without documented compatibility can produce visible color streaks or localized soft spots due to pigment settling and oligomer lot variation.
This material pair is intended for opaque visual prototypes, jigs, fixtures, and low-temperature end-use components; it is not a substitute for high-temperature stereolithography resins or filled thermoplastics. Components exposed to continuous load above 50 °C may creep because the heat deflection temperature of the unfilled photopolymer is near the top of the wax-removal envelope. The material set is not certified for food-contact, implant, or drug-delivery use unless a separate manufacturer statement and regulatory document is provided for the specific application.
Compared with transparent VisiJet CR-CL resin, the black and white grades add opacity and color contrast but may show stronger orientation-dependent mechanical scatter because the pigment packages alter UV penetration during cure. Compared with VisiJet CE-NT natural elastomeric material, which delivers much lower Shore D hardness and higher elongation for gasket-like parts, the RBK-RWT-L50 pair is rigid and is selected when dimensional stability, snap-fit prototyping, or paint-free contrast is required rather than rubber-like compliance. Compared with VisiJet M2 CAST castable material used for investment casting patterns, the RBK-RWT-L50 pair has ash content and burnout behavior that is not intended for foundry wax-pattern replacement. Published data for this specific paired-material kit is limited to the individual resin datasheets; no independent interlaboratory study for the paired-materials configuration is publicly available.
