3D Systems PSLA 270 Materials Guide

Direct answer: the current 3D Systems PSLA 270 page names ten compatible Figure 4 resins: Tough 75C FR Black, F3 Orange, HI TEMP 300-AMB, Rigid Composite White, Tough 60C White, Rigid Gray, Rigid White, FLEX-BLK 20, EGGSHELL-AMB 10 and PRO-BLK 10. Treat other Figure 4 resins as confirmation-required until 3D Systems identifies a current PSLA 270 profile and complete workflow. Treat third-party resin as unsupported or poor fit by default.

The list is only the first gate. Useful compatibility connects the exact resin SKU and lot to a released 3D Sprint profile, the correct vat and Material Delivery Module, layer settings, hand-pour or auto-fill handling, washing chemistry, drying and post-cure instructions. It also includes ventilation, PPE, waste handling and finished-part qualification. A resin does not become supported merely because it responds to the projector wavelength or belongs to the broader Figure 4 family.

PSLA 270 material compatibility at a glance

Material lane	Verdict	Decision boundary
Rigid Gray, Rigid White and PRO-BLK 10	Current exact-page compatible list	General rigid production routes; qualify the actual wall, load, cure, environment and assembly instead of transferring a brochure property.
Tough 60C White and Tough 75C FR Black	Current exact-page compatible list	Choose the exact impact, heat and flame context; the resin's classification does not certify a finished enclosure or assembly.
FLEX-BLK 20	Current exact-page compatible list	Flexible does not mean proven for every seal, bellows, hinge, fluid, outdoor exposure or repeated-compression duty.
HI TEMP 300-AMB	Current exact-page compatible list	A stated HDT is not a universal continuous-use temperature, loaded fixture life or mold-cycle promise.
Rigid Composite White	Current exact-page compatible list	Confirm mixing, vat condition, profile, washing and the real stiffness, wear and dimensional requirements.
EGGSHELL-AMB 10	Current exact-page compatible list	A sacrificial silicone-tooling route; validate shell drainage, removal, silicone chemistry, inhibition and final mold quality.
F3 Orange	Current exact-page compatible list	A high-visibility rigid route; color and surface positioning do not prove a mechanical, outdoor or safety application.
Other Figure 4, dental, medical, castable or biocompatible-capable resins	Confirmation required	Portfolio membership does not establish a current PSLA 270 profile, package, cure, contact classification or regulatory route.
Third-party, mixed, expired or unidentified resin	Unsupported or poor fit by default	Apparent cure does not establish exposure, vat compatibility, accuracy, properties, safety, warranty or repeatability.

The exact product-page list controls the first decision

The current PSLA 270 product page ties ten material cards directly to this machine. That is stronger evidence than a generic resin catalog because it names the printer and each resin together. The page also says the machine is designed for the Figure 4 range and uses broad phrases such as rigid, tough, durable, castable, heat-resistant and biocompatible-capable. Those category statements do not silently add every current or future Figure 4 formulation to the exact list.

The February 2026 PSLA 270 brochure supplies current manufacturer system context. Before purchasing resin or quoting a job, obtain the current regional SKU, supported 3D Sprint release and profile, approved layer choices, vat assignment, washing sequence and post-cure schedule. Material availability and workflow support can vary by country, packaging and software release.

Use the live list as a routing tool, not a promise that every geometry will work. The PSLA 270 has a 242 × 265 × 300 mm stated build volume and dual projector architecture, but part cross-section, orientation, support, resin behavior, recoating and thermal history still affect results. Printer envelope and projector power do not prove a resin profile.

Rigid, tough and flame-retardant are different decisions

Rigid Gray, Rigid White and PRO-BLK 10 are the broad rigid-production group. Start there for housings, fixtures, covers and appearance parts only after defining the actual load, temperature, impact, fastener stress, chemical contact and expected life. Manufacturer property tables describe specified specimens and conditions; they are not independent testing of a customer's thin wall, snap, boss or threaded feature.

Tough 60C White and Tough 75C FR Black answer different constraints. The current Tough 75C FR Black route is evidence for that named formulation and its stated test context. It does not make every black resin flame retardant or certify a finished electrical enclosure. Preserve thickness, conditioning, test method and traceability, then determine whether the complete part or assembly needs its own evaluation.

If impact margin is the real requirement, compare the named tough resin data in the relevant conditioned state. If flame performance governs, begin with the exact FR grade and applicable evidence. Do not select a resin simply because the name contains the highest temperature or strongest adjective.

Heat, composite and flexible labels need operating conditions

The official HI TEMP 300-AMB page provides manufacturer application and test context. Its heat-deflection statement is not automatically a continuous-use rating, electrical RTI, sterilization limit, mold life or proof for a loaded fixture. Define peak and continuous temperature, load, dwell, cycles, contact chemistry, dimensional allowance and acceptable aging, then validate the printed geometry after the prescribed wash and cure.

Rigid Composite White is filled, so material preparation, suspension, vat condition and cleaning can matter as much as its headline stiffness. Confirm the current PSLA 270 instructions rather than assuming the same handling used for an unfilled rigid resin. A composite label also does not establish wear resistance, dielectric behavior, machinability or a universal dimensional result.

FLEX-BLK 20 is the exact-page flexible option, but flexible is not synonymous with elastomer qualification. Seals, bellows, grommets and repeated-bend parts need hardness, elongation, tear path, compression set, fluid exposure, temperature, UV, cycle count and inspection criteria. For a different closed-workflow resin machine, compare the HeyGears Reflex 2 material guide; its resin and profiles do not transfer to the PSLA 270.

Eggshell, casting and regulated applications require downstream proof

Figure 4 EGGSHELL-AMB 10 is positioned as sacrificial tooling for silicone casting. The printed shell is only an intermediate. Compatibility includes drainage, cleaning, shell removal, silicone inhibition, venting, surface transfer and the silicone manufacturer's process. A printable shell does not guarantee final mold dimensions, surface or service life.

The current exact page does not list JCAST or another investment-casting resin among its ten material cards. Do not infer PSLA 270 support from another Figure 4 printer or a portfolio page. Obtain written exact-machine profile and workflow confirmation, then qualify investment, burnout, furnace ventilation, alloy, sprue and foundry practice separately.

The page's application language includes medical uses requiring biocompatibility and/or thermal resistance, but that is not a blanket finished-device claim. A specific resin needs the intended contact type and duration, current processing instructions, traceability and applicable biological evaluation. Printing on the PSLA 270 does not by itself make a part approved, sterile, implantable or suitable for patient contact.

Vat and Material Delivery Module ownership matter

The PSLA 270 is designed around a mobile cart carrying the vat, elevator, displacer, recoater and Material Delivery Module. That architecture is intended to make material changes practical without treating the resin-wetted hardware as generic. Assign and label vats and wetted components according to current 3D Systems instructions. A fast cart swap is not permission to mix residue, transfer an unknown resin or skip inspection.

Hand pouring and the auto-fill resin pump are two delivery modes, not proof that every resin is available or supported in every package. Confirm the exact bottle or supply format, fill procedure, mixing or conditioning requirement and MDM compatibility. Keep lot, opening date, storage, vat residence and exposure history where the process or customer requires it.

During a change, follow the manufacturer procedure for draining, covering, moving, storing and inspecting resin and the vat assembly. Do not improvise solvent flushing or combine leftovers. Cross-contamination can change cure, appearance, properties and downstream qualification even when a test exposure appears solid.

Washing, UV and facility safety boundaries

Uncured photopolymer, contaminated tools and wash liquid require chemical controls. Follow the current 3D Systems instructions and exact resin safety data sheet for gloves, eye and skin protection, ventilation, spill response, storage, incompatibilities and disposal. Keep food and drink away, cover resin when it is not being handled and never pour uncured residue or contaminated wash liquid into a sink.

Washing may introduce flammable or otherwise hazardous solvents. Keep containers closed, control ignition sources, use compatible electrical equipment and ventilation, and follow local fire and waste rules. UV post-curing adds optical, heat and electrical boundaries; use the approved cure unit and cycle with its guards and interlocks intact. GoodPrints is not the final chemical, fire, electrical, medical or facility-safety authority.

NIOSH additive-manufacturing guidance supports a hierarchy-of-controls approach that includes enclosure or local exhaust where appropriate, housekeeping, PPE and exposure assessment. It does not replace the printer manual, exact SDS, wash and cure instructions, an industrial hygienist, the fire authority or the responsible EHS organization.

Finished-part properties still need qualification

3D Systems' speed, accuracy, surface, stability and material claims are manufacturer claims with defined scope, not independent testing of every part. Preserve traceability for printer and projector state, software and profile version, resin SKU and lot, vat and MDM, layer settings, orientation, supports, wash, dry and cure. Inspect the real features that govern the job.

UV, humidity, temperature, chemicals, notches, fasteners, wall thickness and time can change useful behavior. Product-page statements about accelerated aging are not universal outdoor-service guarantees. Safety-critical, medical, electrical, flame-rated, pressure, food-contact and other regulated uses require their own standards and responsible approval.

For another 3D Systems projection workflow, the Figure 4 135 material router covers a different machine and its own validated list. For a larger-format resin decision, use the Formlabs Form 4L guide. For a lower-cost large resin platform, review the Elegoo Jupiter SE material guide. None of those machines transfers material support to the PSLA 270.

Buyer and owner decision

Choose the PSLA 270 when one or more of its ten current exact-page Figure 4 resins fits the application and the larger projector-SLA envelope, repeat production and managed vat-change workflow matter.
Choose the exact resin by the finished part's load and environment, then verify the current profile, supply format, vat/MDM assignment, wash and post-cure route before committing production.
Pause for written confirmation when the job depends on another Figure 4 resin, a regulated contact classification, an exact cartridge or pump route, or a workflow not named on the current page.
Choose a different platform when the required feedstock is filament, powder, pellet, metal, ceramic, paste or an unsupported third-party resin.
Outsource or prototype first when resin demand is intermittent or the organization does not own chemical handling, washing, curing, inspection and waste responsibility.

For a defined part, start with the custom-part material chooser, review the custom-printing service FAQ, request a scoped GoodPrints quote, or use the JC Print Farm route. A general quote does not replace regulated-device or safety qualification.

Bottom line

The current PSLA 270 page names ten compatible Figure 4 resins. That makes it a credible production-resin platform, but not an open vat where any Figure 4 or 405 nm resin is automatically supported. Treat exact resin and profile identity, vat and MDM, washing, drying, post-curing, ventilation, PPE, waste and finished-part evidence as one compatibility decision.
