In the EV power electronics enclosure prototyping workflow, VisiJet M2 EBK is used only for form-fit-tolerance verification before steel rule die cutting. The build is run on a ProJet MJP 2500/2500 Plus with a build volume of 294 × 211 × 144 mm and a layer thickness of 32 µm. The flange gasket model has a wall thickness of 1.2 mm to 1.5 mm. The channel fill ratio is maintained at 1.0:1.1 relative to the mating groove volume. The mating surface flatness is controlled to 0.05 mm per 100 mm. The printed flange thickness is measured at eight points. Variation must remain within ±0.10 mm. This ensures the compression deflection assumption holds. The printed flange is compressed to 15–25% deflection during fitment testing. Compression set is evaluated according to ASTM D395-18 Method B after 22 h at 70 °C. Test coupons are cut from the same build orientation as the production flange. The build orientation is XY plane with the compression face parallel to the print platen. This orientation minimizes the effect of layer boundaries on seal compression. Support wax is removed in an oven cycle held below 70 °C. The part is then cleaned in an ultrasonic bath containing isopropyl alcohol for 10–20 min. Drying is performed at 20–25 °C for 30 min. No thermal post-cure is applied. The terminal component is a form-fit-gauging fixture, not a production seal. Continuous contact with dielectric coolant or mineral oil is not evaluated. Published data for fluid resistance of this specific grade is limited. The prototype is used within a dry enclosure environment only. This is a critical boundary. No UL 94 V-0 rating is claimed for the material. The design validation workflow uses the printed gasket as a dimensional surrogate. It verifies groove fill, bolt compression, and lid deflection before injection mould tooling is cut.
Short-run substitution is limited to non-patient-contact training housings and engineering prototypes. The material is not supplied with an ISO 10993-1 biological evaluation master file. End-user exposure assessment is not provided by the resin manufacturer. For this application, the process begins with a 32 µm layer height on a MultiJet printer. The composition is single-component; no meter-mix or degassing step is required. Support wax is removed in an oven cycle held below 70 °C. The part is then washed in isopropyl alcohol in an ultrasonic bath for 10–20 min. After drying at 20–25 °C for 30 min, the Shore A durometer is checked with ASTM D2240-15e1 using a 6 mm-thick coupon. The result must fall within the manufacturer’s specified acceptance band before any mechanical test is performed. The snap-fit retention force is measured on a universal testing machine at 50 mm/min. Side-load deflection is applied at 1 mm/min to avoid dynamic overshoot. The terminal component is a surrogate housing for reusable surgical training devices. It is repeatedly snap-fitted and flexed. It is not sterilized by autoclave. Steam sterilization is not recommended because it can alter compression set and surface tack. The printed housing is used only in a controlled training environment. It must not enter a clinical setting. This is a defined operational boundary. The part is cleaned with a mild soap solution and air-dried. No alcohol-based hospital disinfectant is used. Published data on repeated disinfection compatibility for this grade is limited. The short-run build is compared with a production liquid silicone rubber moulding before any design freeze.
For consumer electronics soft-touch keypad membranes, the build is configured with web thicknesses between 0.5 mm and 0.7 mm. The support surface is placed on the non-cosmetic side of the membrane. This preserves the button crown surface. The layer line orientation is set to run parallel with the key travel axis. Total key travel is kept below 0.3 mm. The design ratio of key diameter to web thickness is 8:1 to 10:1. Actuation force is verified on a force-displacement tester fitted with a 5 mm hemispherical probe. Acceptance limits depend on the customer key switch requirement. The printed membrane is conditioned at 23 °C and 50% RH for 24 h before actuation testing. This conditioning reduces short-term moisture-driven stiffness variability. The membrane is not tested below 0 °C because impact strength data is not supplied. The resin system is supplied under a REACH 1907/2006 Article 33 declaration. The user must perform SVHC screening for the finished assembly. RoHS compliance is documented by the manufacturer under Directive 2011/65/EU Annex II; the printed part remains a homogeneous material only if no post-coating is added. If a hard coat is added, the compliance file must be re-evaluated. The terminal component is a membrane switch cover over a rigid polycarbonate base. The elastomer is bonded with an optically clear pressure-sensitive adhesive. The adhesive is specified by the end-user. This avoids silicone migration concerns in the final paint line. The printed membrane is not painted because solvent-borne coatings may swell the elastomer. This is a process boundary. The finished keypad is tested for 100,000 cycles at 2 Hz. Failure is defined as a crack longer than 0.5 mm at the dome root. The build is run as a single-piece membrane with integrated spacers. This reduces assembly variation. No separate die-cut gasket is required in the short-run consumer remote control development.
In fume extraction and air-assist duct prototypes, the material serves as a low-pressure bellows section with internal diameters from 12 mm to 40 mm. The wall is set at 1.0 mm to 1.2 mm. The convolute pitch-to-wall ratio is held between 3:1 and 5:1. Below 3:1, the convolutes are difficult to clean in support removal. Above 5:1, the bellows tends to collapse under its own weight. The part is printed in the Z-axis direction to maximize convolution uniformity. Support wax is drained through an open end. Cleaning uses a two-stage isopropyl alcohol rinse. The final rinse is heated to 35 °C for 15 min. A flow bench test is run at 200 Pa differential pressure. The bellows must not exhibit visible necking. The bellows is inspected under a 10× optical microscope at each convolute root. Any crack exceeding 0.2 mm rejects the part. The wall should be free of trapped support wax. Residual wax can close the air path. If residual wax is detected, the part is returned to the ultrasonic bath. This process is for functional airflow prototypes only. The material is not rated for flammability under UL 94. It is not suitable for plenum-rated building installations. It must not contact tobacco smoke or aggressive solvent vapors. Dimensional change after 24 h at 23 °C and 50% RH is checked with a calibrated shadowgraph. Wall thickness is measured at five points on each convolution. The terminal component is an intake duct segment for a benchtop spectrometer cooling path. It is replaced after 200 h of test operation or when surface cracks are detected. The geometry is then transferred to compression molding if the test passes. This is a real downstream hand-off.
When a cable strain relief boot is printed in the Z-direction, its tensile elongation at break can differ from the XY-direction coupon. Published orientation-specific data for this resin is limited. A pre-production build must include a full factorial set of three tensile coupons per orientation. The coupons are tested under ASTM D412-16 Die C. The acceptance rule is not a single-point value. The low orientation result must remain above 70% of the high orientation result. This protects against hidden anisotropic failure. The boot is designed with an inner sleeve wall of 1.0 mm for cable diameters from 5 mm to 8 mm. The strain relief length is 3.5 times the cable jacket diameter. The process prints the boot at 32 µm layers. The support material is removed from the internal cable pathway using a low-temperature melt cycle. The flex test uses a mandrel radius of 2.5 mm. This matches the anticipated enclosure bracket radius. The boot is attached to the cable with a cyanoacrylate fixture adhesive. The adhesive is allowed to cure for 24 h at 23 °C. The pull-out force is recorded after flex testing. It must remain above 50 N. That value is derived from the customer bracket retention specification. The terminal component is a flex test specimen. It is mounted in a two-station cable flex machine with a ±90° bend angle and 30 cycles per minute. The boot must endure 5,000 cycles without tearing at the entry radius. This test is aligned with the strain relief intent of IEC 62368-1. The part undergoes visual inspection at 500-cycle intervals. Cracks indicate failure. This application is only for functional testing, not safety certification. The environmental condition is 23 ± 2 °C. If the cable will be used outdoors, the material must be separately evaluated for UV stability. The datasheet does not list QUV or xenon arc data. This transparency is necessary. The final component is a silicone replacement boot for a battery-powered field instrument. The short-run build is used to validate cable pull-out force and bend fatigue before committing to liquid silicone rubber tooling.
A compliance screening matrix is applied before any of the preceding builds are released to the next process step. The matrix summarizes the standard or directive, the test condition, and the boundary that triggers rejection.
| Application cluster | Standard or directive | Test condition | Rejection trigger |
|---|---|---|---|
| EV enclosure gasket | ASTM D395-18 | 22 h at 70 °C | Compression set above 20% |
| Medical training housing | ASTM D2240-15e1 | 6 mm coupon at 23 °C | Shore A outside manufacturer tolerance |
| Consumer keypad | REACH 1907/2006 | SVHC screening | Candidate list substance above 0.1% w/w |
| Air duct bellows | UL 94 | Not rated | Plenum-rated use requested |
| Strain relief boot | ASTM D412-16 | Zero and 90° orientation coupons | Low orientation below 70% of high orientation |
Inside optical alignment fixtures, the printed elastomer is used as a damping pad under kinematic mounts. The pad is designed with a compression preload of 5–10% of its free thickness. Free thickness is 3 mm. The diameter is 12 mm. The load path is normal to the build plate. This avoids shear loading on layer interfaces. The process includes an initial cycling step. Each pad is compressed 20 times to 15% strain before installation. This stabilizes the stress-strain response. Vibration transmissibility is checked on an electrodynamic shaker using a 5–200 Hz random profile. The shaker input is a flat random profile from 5 Hz to 200 Hz. The vibration level is set to 0.01 g²/Hz. The transmissibility peak is compared with the metal-only fixture. A measurable reduction above 10% is considered useful. If no reduction is observed, the pad geometry is changed. The thickness is increased in 1 mm increments. The diameter is held constant. The design iteration is limited to three builds to control cost. Published damping data for this grade is limited. The design is treated as a spring-damper cushion rather than a vibration isolator. The mounting pad is bonded to an anodized aluminum base with a thin structural acrylic adhesive. The bond line is 0.10–0.15 mm. The assembled fixture is conditioned at 23 °C for 24 h before use. The terminal component is a laser bench foot pad. It protects the kinematic mount from bench-top fan and pump vibrations. The pad must not be exposed to acetone. Acetone causes cracking. The customer uses only isopropyl alcohol for cleaning. The paperless work instruction includes this solvent restriction. This component is not part of the optical path. No transmissive optical property is assessed. After 1,000 h, compression set is re-measured. The limit is 10% permanent set under the specified preload. If the pad exceeds that value, it is replaced. This is a standard maintenance interval for the lab fixture.
ATEX enclosure prototypes use the elastomer as a temporary ingress-sealing strip. This is not a certified ATEX component. The printed strip is inserted into a cast aluminum enclosure lid. The groove is 3.0 mm wide. The strip is printed with a cross-sectional width of 2.8 mm. The height is 2.0 mm. The closure compresses the strip to 25% of its height. The printed strip is wiped with isopropyl alcohol before installation. It is not wetted with lubricant because the groove corner may extrude the elastomer. The torque wrench is calibrated to ±5% of the target value. The closure is performed at 23 °C. High-temperature closure is not assessed. The lid is cycled 100 times with a torque wrench set to the enclosure manufacturer’s specification. After cycling, the strip is removed and measured at three points along each side. The recovery must exceed 90% of the original height. The material composition is single-component and does not require mixing. No volatile organic compound is released during printing. However, the liquid resin should be handled under local extraction. The support removal process has a maximum allowable temperature. Exceeding this temperature causes permanent deformation. The part is allowed to rest at 23 °C for 4 h before measurement. This is a process limit. The ingress trial uses a dust chamber with a 1 µm particle aerosol. The strip is not subjected to explosive gas. It is used only to check mechanical compression recovery. This limitation is important. The terminal component is a short-run cover seal for an explosive-atmosphere enclosure prototype. The material is not certified to ISO 80079-36. It is used only for mechanical fitment and ingress trial, not for ignition hazard assessment. If the enclosure requires an approved sealing element, the printed strip must be replaced with a certified ethylene propylene diene monomer gasket. This substitution boundary is stated in the engineering change note.

3D Systems VisiJet M2 EBK is a UV-curable elastomeric photopolymer engineered for MultiJet Printing on the ProJet MJP 2500 and ProJet MJP 2500 Plus additive manufacturing platforms. The uncured material is a black, low-viscosity liquid formulated for piezoelectric drop-on-demand jetting; layer thickness is typically 32 µm. After UV irradiation, the acrylate-functional oligomer network crosslinks into a rubbery solid with an opaque black cross-section. Manufacturer-published typical properties include a Shore A hardness of 30 per ASTM D2240, tensile strength of 1.0 MPa and elongation at break of 250 % per ASTM D412, and tear strength of 4.6 kN/m per ASTM D624. Solid density is approximately 1.0 g/cm³ per ASTM D792. The product is intended for functional elastomeric prototypes, short-run seals, gaskets, paint-masking fixtures, grips, vibration isolators, and connector boots. Unlike fused filament or laser-sintered flexible materials, M2 EBK builds with smooth sidewalls and supports fine internal channels through a sacrificial wax support system. The printed material is not a thermoplastic elastomer; after cure it does not melt and cannot be reprocessed thermally.
Continuous sealing performance is controlled by compression set, stress relaxation, and fluid resistance rather than tensile elongation alone. For VisiJet M2 EBK, published compression-set data under ASTM D395 Method B are limited; sealing qualification should therefore measure compression set at the actual service temperature, installed compression ratio, and recovery time. The material is best applied in static seals with peak compressive strain below 15 %. Higher compression ratios may accelerate stress relaxation and cause loss of sealing contact pressure after thermal cycling. Prolonged contact with polar solvents such as ketones, esters, and chlorinated hydrocarbons can soften the crosslinked network; hardness, mass change, and volume swell should be evaluated by ISO 1817 and ASTM D471. Non-polar hydrocarbon exposure may be less aggressive, but fuel and oil sealing should not be assumed without immersion testing. Service above 50 °C may increase compression set and reduce tear resistance, so applications above this threshold require continuous-load relaxation testing. Because the network is UV-crosslinked, extended outdoor exposure can increase crosslink density and reduce elongation at break.
| Property | Test method | Typical value |
|---|---|---|
| Hardness | ASTM D2240 | 30 Shore A |
| Tensile strength | ASTM D412 | 1.0 MPa |
| Elongation at break | ASTM D412 | 250 % |
| Tear strength | ASTM D624 | 4.6 kN/m |
| Liquid viscosity at 30 °C | ASTM D2196 | 12–16 mPa·s |
| Solid density | ASTM D792 | 1.0 g/cm³ |
Layer-wise UV cure introduces anisotropic mechanical response that is not reflected in bulk datasheet values generated from printed panels. Z-axis tensile elongation and tear strength can be lower than in-plane values because interlayer crosslink density is affected by oxygen inhibition, UV attenuation, and the time interval between successive layers. The magnitude of this reduction depends on build orientation, layer thickness, and post-cure; published data for this specific configuration is limited. When designing sealing ribs or flexural snap features, the flexing axis should be oriented in the XY plane, and sharp corners perpendicular to the Z-axis should be avoided. Thin ribs below 0.5 mm can tear during support removal or exhibit lower tear resistance. Corners with radii smaller than 0.5 mm can act as tear initiation sites under repeated extension. For dynamic flexing, strain per cycle should remain below 5 % if service life exceeds 10,000 cycles, and validation should follow ASTM D430 or an equivalent flex fatigue method. Batch-to-batch variation on production machines is controlled by sealed cartridge storage, resin recirculation before jetting, and maintenance of printhead temperature within the manufacturer’s specified range.
Cast urethane gaskets usually provide higher tear strength and lower piece cost at volume, but they require mold tooling and lead times measured in weeks. M2 EBK becomes a practical replacement when part quantities are below 100 units, when sealing geometry changes frequently, or when internal channels and undercuts cannot be molded in a single operation. The trade-off is lower tear strength and anisotropic elongation in the Z-axis. Cast urethane with Shore A 30–40 hardness may exhibit tear strength two to three times higher than the printed material, so load-bearing gaskets should be redesigned with thicker sidewalls and a compression stop. For vacuum workholding masks, leak tightness must be validated because microvoids and incomplete interlayer cure can create leakage paths. Compressibility and recovery should be measured per ASTM F36, and tear resistance per ASTM D624 before replacing a cast or die-cut part. In masking applications for plasma treatment or painting, the black color of EBK provides light blocking and simplifies visual inspection, but the user must confirm that no low-molecular-weight material migrates to the substrate. Surface energy testing per ASTM D2578 or extractables testing may be required for clean-release applications.
Compared with rigid ProJet MJP materials such as VisiJet M2R-CL, the EBK grade provides high elongation at the expense of modulus and creep resistance. It differs from the natural elastomeric grade in pigment loading and appearance; opacity and color stability should not be assumed to transfer from natural to black versions without reprinting a test coupon. The material cannot be directly compared with laser-sintered TPU powders because the UV-cured network is thermoset and does not exhibit a true melting transition. This difference becomes important when parts are exposed to high-humidity environments or detergent washing; swelling and hydrolysis resistance should be tested per ISO 62 and ISO 175. For electronic enclosures, cured parts may evolve volatile condensable species; if used inside sealed optical or electronic modules, outgassing should be evaluated per ASTM E595.
On the ProJet MJP 2500, the build chamber measures 294 mm × 192 mm × 150 mm, and parts are surrounded by sacrificial wax support material that must be removed after printing. Support removal is performed in a heated bath or oven; exceeding the recommended temperature or leaving thin elastomeric sections in the bath too long can produce surface tack, deformation, and loss of fine sealing ribs. Production failure modes observed on manufacturing lines include tearing of thin overhangs during manual wax removal, wax residue in blind holes, and softening of unsupported walls when bath temperature exceeds the material’s dimensional stability threshold. After support removal, parts may be rinsed with isopropyl alcohol or a manufacturer-approved solvent. Excessive solvent contact can extract low-molecular-weight species and increase surface hardness; immersion should be limited to 5 min unless validated for the specific geometry. Post-cure requirements should follow the manufacturer’s current processing bulletin; published data for additional thermal post-cure effects on EBK are limited. Dimensional inspection should follow ISO 291 conditioning at 23 °C and 50 % RH for 24 h before measurement. Batch-to-batch differences in support wax formulation can influence adhesion to the elastomer; first-article trials should include a tear-out test of blind holes and thin ribs.
Uncured resin may be classified as skin sensitizer under EC 1272/2008; handling should use nitrile gloves, chemical safety goggles, and local exhaust ventilation. Cartridges should be stored at 15–25 °C in sealed, light-excluding containers and used within the manufacturer’s stated shelf life, commonly 12 months from date of manufacture. Opened cartridges should be consumed within 30 days to prevent viscosity drift and pigment settling. Cured parts are not classified as hazardous, but grinding or machining can generate particulate that should be captured by local exhaust. The product is not intended for direct food contact or long-term implantation; no FDA clearance is implied. Compliance with 2011/65/EU RoHS Recast and REACH candidate list obligations should be confirmed from the supplier’s current material compliance documentation. The following control points are commonly requested for qualification:
| Control point | Relevant standard/regulation | Condition or note |
|---|---|---|
| Uncured resin flash point | ASTM D3278 / supplier SDS | Closed-cup method |
| Skin sensitization | EC 1272/2008 | Uncured resin |
| Cured part outgassing | ASTM E595 | Total mass loss and CVCM |
| Seal compressibility and recovery | ASTM F36 | Gasket and mask applications |
| Compression set | ASTM D395 Method B | Sealing load retention |
| Chemical immersion | ISO 1817 / ASTM D471 | Fluid compatibility |
On multi-machine production lines, the largest source of property drift is not the printer itself but the storage condition of partially used cartridges. Resin exposed to office lighting and humid air can absorb moisture, raising viscosity and changing jetting drop mass. Printhead temperature compensation cannot fully correct for viscosity above the specified range; the result is missing jets and non-uniform layer thickness at the edges of the build envelope. Production control plans should therefore log cartridge opening date, storage temperature, and relative humidity. If ambient relative humidity exceeds 60 %, pre-condition cartridges in a dry cabinet before use and minimize open time. The material should not be combined with amine-based additives or coatings because amine species can react with residual acrylate groups and accelerate surface crosslinking or tack. For parts that require painting or adhesive bonding, surface preparation should be validated by ASTM D3359 cross-cut adhesion or ISO 2409. The operational boundary for sustained mechanical loading is conservative; service life is best confirmed by functional testing on the actual assembly rather than by extrapolation from tensile data alone.
