3D Systems VisiJet RWT-RCL-R11 is a paired photopolymer cartridge set combining VisiJet CR-WT 200, an opaque white rigid build material, with VisiJet CR-CL 200, a transparent rigid build material, for simultaneous deposition in MultiJet Printing systems configured for multi-material operation. The part number stem RWT-RCL denotes the rigid white/rigid clear material pairing, while the suffix R11 identifies the two-cartridge packaging configuration. The product is specified for prototype builds in which both load-bearing white regions and optically inspectable clear regions are required in a single part without adhesive bonding or mechanical fastening.

Mechanical property data for the two materials are generated from printed coupons using ASTM D638-14, ASTM D790-17, ASTM D648-18, and ASTM D256-10. Because material jetting produces anisotropic strength fields, datasheet values should be treated as in-plane figures obtained from default X-Y build orientation. Through-thickness and interfacial strength values may fall below flat coupon results and should be measured before load-bearing deployment. Representative published ranges are summarized below.

VisiJet RWT-RCL-R11 material set architecture across the MJP 5600 platform

The paired cartridge architecture keeps the white and clear phases fluidically isolated until deposition. On a ProJet MJP 5600 configured for multi-material operation, the build envelope measures 518 × 381 × 300 mm and the printhead addressability is 1200 × 1200 × 900 dpi. The two materials are heated in separate reservoirs to bring viscosity into the jetting range, then deposited through individual printhead channels and planarized in the same layer pass. The white phase contains an inorganic pigment dispersed in a methacrylate-functional matrix; the clear phase is formulated for optical transmission after ultraviolet post-cure. The materials are not blended before jetting. They remain separate in the fluid path and combine only as adjacent voxels inside the build volume.

Cross-loading the RWT-RCL-R11 cartridge set into a platform not configured for the paired rigid white/rigid clear workflow is rejected by the machine firmware. Field documentation indicates that the main operational failure mode during unattended builds is cross-contamination of the clear reservoir through an interrupted waste-drain cycle or a fouled planarizer path. When pigment transfers into the clear phase, the resulting parts exhibit faint white haze that cannot be removed by standard post-cure or polishing. The machine’s purge routine reduces this risk, but it does not eliminate the need for periodic planarizer inspection under continuous multi-material production.

Because MultiJet Printing cures photopolymer voxels in sequential planar layers, tensile response is neither isotropic nor homogeneous. A tensile bar printed with its long axis in the X-Y plane returns values closest to the datasheet range. The same bar printed along the Z axis places interlayer photopolymerization boundaries directly across the load path. Published data for the Z-axis tensile strength of VisiJet CR-CL 200 are limited. At the white/clear interface, the two voxel populations are co-planarized and UV-cured in the same layer pass rather than joined by a secondary adhesive. This produces an interface that is closer to intralayer strength than to a solvent-bonded joint, but edge delamination can still occur if chamber temperature deviates outside the machine-controlled envelope or if partially cured resin accumulates on the planarizer blade.

What service temperature limit is imposed by the clear rigid phase?

Thermal deformation in the clear phase governs the continuous load-bearing envelope of the multi-material assembly. Under ASTM D648-18 at 0.455 MPa, the clear material reaches deflection in the 45–52 °C range, while the white phase may tolerate slightly higher temperatures. For sustained mechanical loads on clear load paths, the assembly should be classified below this range rather than averaged across the two materials. Unstressed optical windows may tolerate short excursions to 55 °C, but published data for this specific configuration are limited. At the white/clear transition, differential thermal expansion during post-cure oven ramp-down can generate interfacial shear stress. A controlled cooling profile reduces visible craze, whereas rapid removal from the UV chamber after post-cure has been associated with edge haze at the interface in multi-material builds.

Immersion exposure to aggressive solvents is a more significant operational boundary than humidity uptake. Ketone-based solvents and chlorinated solvents should be avoided because the methacrylate network swells and can craze, particularly at the white/clear interface where residual stress is concentrated. Brief wiping with isopropyl alcohol is used for surface cleaning, but prolonged immersion can reduce surface hardness. The material set is not marketed as a chemical-resistant engineering plastic. Components intended for repeated exposure to hydrocarbon streams, glycol coolants, or aqueous cleaning baths at elevated temperature require end-use qualification under the actual fluid and thermal cycle.

When the white/clear pair replaces bonded subassemblies in liquid-handling hardware

When the RWT-RCL-R11 pair is used for a single-build liquid-handling manifold, the design objective is usually to replace a two-part bonded polycarbonate or acrylic assembly with an integrated housing that includes transparent viewing windows. The clear phase permits visual confirmation of liquid level or suspended particulate, while the white phase provides contrast for image-based inspection and reduces transmitted light through non-window regions. Because no adhesive bondline exists at the material transition, the dimensional tolerance stack is not influenced by bondline thickness variation. However, internal channel roughness is governed by the layerwise deposition process and support-material removal. Flow-testing on actual printed geometry is required for pressure-drop correlation; published data for this specific configuration are limited.

Support removal requires accessible drain paths. Wax support material is melted from the part and followed by an ultrasonic or solvent-assisted rinse. Blind channels that retain support wax will exhibit optical occlusion and may also create localized pressure accumulation during thermal wax removal. In clear regions, any residual wax film left after rinse produces immediate visible haze. The manufacturer’s post-processing documents specify minimum channel diameters and drain-hole placement criteria for multi-material parts. Designs that violate these criteria often require sectioning or destructive inspection to verify clear-channel cleanliness.

Dimensional fidelity is bounded by planarizer condition and support-access geometry

Dimensional tolerance data for the pair are orientation-dependent. Shrinkage is higher in the Z axis than in the X-Y plane because of layer-by-layer photopolymerization contraction. Typical printed feature accuracy is consistent with a 32 µm layer thickness default on the ProJet MJP 5600, but the achievable linear tolerance on small features depends on support-access geometry, planarizer wear, and the thermal uniformity of the build chamber. Features below 1 mm in the clear phase may show reduced edge definition if the support material does not release cleanly. The white phase masks minor edge artifacts more effectively than the clear phase, which means that dimensional inspection of critical transparent features should include optical surface roughness measurement rather than touch-probe inspection alone.

Relative to single-material VisiJet CR-WT 200 or VisiJet CR-CL 200 cartridges, the RWT-RCL-R11 bundle does not alter the individual polymer chemistry. The material difference is the simultaneous availability of both phases in one build. Compared with elastomeric MultiJet materials, the CR-WT 200/CR-CL 200 pair exhibits higher tensile modulus and lower elongation at break, making it unsuitable for snap-fit closures requiring recoverable strain above 10%. Compared with high-temperature rigid build materials, the 45–52 °C heat deflection temperature of the clear phase restricts use in engine-compartment, autoclave, or steam-sterilization fixtures. Compared with machined clear acrylic or polycarbonate optics, CR-CL 200 has lower scratch resistance and requires surface finishing to approach the clarity of cast sheet. The multi-material set is therefore positioned for prototype assemblies and short-run inspection aids where integrated opaque and transparent rigid zones reduce assembly labor, not for replacement of production thermoplastics in long-duration load-bearing service.
