Direct answer: 3D Systems' current material finder assigns 23 named resins to Figure 4 Standalone. The list spans rigid and tough plastics, clear parts, flexible and rubber-like parts, high-temperature and flame-retardant jobs, medical-capable routes, jewelry and investment-casting patterns, and sacrificial silicone tooling. That is a broad range, but it is not open-resin permission. A useful compatibility decision joins the exact resin SKU and lot to a released 3D Sprint profile, the manual-feed and tray workflow, washing, drying, UV post-curing, inspection and the finished part's real duty cycle.
Figure 4 Standalone is positioned for same-day prototyping and low-volume production. Its compact single-printer workflow uses manual material feed and separate cleaning, drying and curing units. That makes it more flexible than a dedicated automated cell for frequent material changes, but every switch still creates a contamination, tray, cleaning, waste and restart decision. Choose it when the 23-resin portfolio and low-volume workflow fit recurring parts; choose a production cell or outsource when scheduling, automated delivery, traceability or finishing capacity is the real constraint.
Figure 4 Standalone material compatibility at a glance
| Material lane | Current verdict | Decision boundary |
|---|---|---|
| PRO-BLK 10; Rigid Gray; Rigid White; Rigid Composite White; F3 Orange | Current exact-machine finder | Candidates for stiff prototypes, housings, fixtures and production parts; validate load, impact, environment, wall, fastener and cure conditions. |
| Tough 60C White; Tough 65C Black; Tough Clear; TOUGH-BLK 20; TOUGH-GRY 10; TOUGH-GRY 15 | Current exact-machine finder | Choose by actual impact, elongation, clarity, temperature and environmental requirements, not the word "tough" alone. |
| FLEX-BLK 20; RUBBER-65A BLK; RUBBER-BLK 10 | Current exact-machine finder | Flexible and rubber-like labels do not prove a seal, bellows, grip, bumper or repeated-flex duty cycle. |
| HI TEMP 300-AMB; High Temp 150C FR Black; Tough 75C FR Black; Tough FR V0 Black | Current exact-machine finder | Thermal and flame data have method, load, thickness and conditioning scope; they do not certify an arbitrary assembly. |
| MED-WHT 10; MED-AMB 10 | Current exact-machine finder | Medical-capable material routes; device contact, cleaning, sterilization, traceability and regulatory qualification still apply. |
| JCAST-GRN 20; JEWEL MASTER GRY | Current exact-machine finder | Pattern materials whose value depends on the complete investment, burnout, furnace, alloy and foundry process. |
| EGGSHELL-AMB 10 | Current exact-machine finder | A deliberately brittle sacrificial shell for silicone tooling, not a general end-use resin. |
| Other Figure 4, dental, third-party 405 nm, mixed, expired or unknown resin | Unsupported or poor fit by default | Portfolio membership or apparent cure does not establish a released profile, accuracy, tray life, properties, safety, support or repeatability. |
The live exact-machine finder owns the starting list
The current Figure 4 Standalone product page links buyers toward the manufacturer's material portfolio, and the live exact Standalone material-finder facet currently returns 23 records. That is the clean public inclusion rule. The broader 3D Systems materials portfolio contains materials for other Figure 4, dental, stereolithography and production systems; a company-wide listing is not an exact-machine release.
The June 2025 Figure 4 materials guide adds application, property and compatibility context. Use it to understand why one formulation may fit a requirement better than another, then confirm the current exact SKU, package, profile, regional release, wash chemistry and cure schedule in the order documentation. Manufacturer pages and finder facets can change, so a saved profile and procurement record matter more than a copied list when production evidence is required.
Manual feed does not mean arbitrary feedstock. Before a switch, identify the tray or membrane state, whether tools may be shared, how residual resin is recovered or discarded, the approved cleaning method, refill and mixing instructions, and the restart acceptance check. Keep old and new resin, wash liquids and tools from silently cross-contaminating each other. A resin appearing in the finder answers the platform question; the released instructions answer the operating question.
Rigid, composite and tough options solve different failures
PRO-BLK 10, Rigid Gray and Rigid White are the general rigid group. Rigid Composite White adds a filled-material decision, while F3 Orange adds a distinct formulation and visibility choice. They may be candidates for housings, covers, fixtures, prototypes and low-volume end-use parts, but "production-grade" is manufacturer positioning rather than proof for a thin wall, loaded thread, snap, clip or chemically exposed assembly. Define sustained and peak load, impact direction, notches, fastener preload, temperature, humidity, UV, fluid contact, cleaning and expected life.
Filled resin can introduce settling, mixing, tray inspection, cleaning and abrasion concerns that an unfilled resin does not. Follow the exact manufacturer's handling instructions rather than improvising agitation or scraping. F3 Orange should likewise be selected for its documented application and process fit, not merely because its color improves visibility. Color, pigmentation and fill can affect exposure and post-processing, which is why profiles are resin-specific.
The six tough materials are not interchangeable colors. Tough 60C White, Tough 65C Black and Tough Clear signal different thermal, appearance and property packages. TOUGH-BLK 20 and the two TOUGH-GRY grades have distinct roles. Preserve test method, specimen orientation, conditioning and cure scope when comparing values. For a clear part, define transmission, haze, surface finish, wall thickness, polishing or coating, UV aging and cleaning. A clear coupon after cure does not prove a durable window or light guide.
Flexible and rubber-like choices need geometry-level evidence
FLEX-BLK 20, RUBBER-65A BLK and RUBBER-BLK 10 occupy different stiffness, tear and rebound lanes. A part bending by hand is not enough evidence for a gasket, bellows, grip, strain relief, bumper or living hinge. Define hardness, minimum wall, bend radius, tear path, compression set, pressure, fluid, temperature, outdoor exposure and cycle count. Then print representative geometry with the released process and test it in the real mating assembly.
Seals need mating-surface finish, squeeze, pressure, dwell and leakage criteria. Flexures need bend radius and cycles. Bellows need trapped-resin drainage and cure access. Grips and wearables add skin-contact and cleaning questions. Washing and post-cure can affect the usable result, so compare materials only after each has completed its specified process. Do not transfer a hardness label into a seal-life claim.
If flexible parts are only occasional, the manual-feed Standalone workflow may be practical. If several materials recur daily, dedicated engines can reduce changeover and contamination burden. The Figure 4 Modular material router owns that scalable multi-engine decision, while the Figure 4 Production router covers a customized integrated production cell.
High-temperature and flame labels stay inside their scope
HI TEMP 300-AMB, High Temp 150C FR Black, Tough 75C FR Black and Tough FR V0 Black answer different questions. Heat-deflection temperature is measured under a stated load and method. It is not automatically a continuous-use rating, electrical RTI, sterilization limit, mold-life guarantee or safe loaded-fixture temperature. Define peak and continuous temperature, load at temperature, dwell, cycles, contact chemistry and allowable dimensional change.
Flame evidence depends on the exact resin, specimen thickness, conditioning and classification. A material result does not certify an arbitrary enclosure, connector, vehicle component or complete electrical product. Preserve resin and lot traceability, use the released profile and cure, and route the finished design through the applicable evaluation. Residual liquid, trapped wash solvent and cure shadows matter because the final part, not an uncured build, carries the duty.
A lower-cost compact printer does not remove facility requirements. Thermal, flame and production claims should be evaluated alongside wash and cure equipment, extraction, solvent storage, electrical service, fire controls, housekeeping and waste handling. If these controls are not wanted in-house, outsourcing is a valid material decision rather than a failure to use the machine.
Medical, casting and sacrificial tooling are process programs
MED-WHT 10 and MED-AMB 10 appear in the current exact-machine finder, but "medical-capable" is narrower than "every printed device is biocompatible." The exact resin and lot, profile, geometry, washing, dry state, cure, residue, contact type and duration, cleaning, sterilization, packaging, traceability and regulatory pathway remain part of the decision. The printer and material do not approve a device by themselves.
JCAST-GRN 20 and JEWEL MASTER GRY are pattern materials. Their success is decided downstream through sprue design, investment compatibility, burnout schedule, ash or expansion behavior, furnace ventilation, alloy, casting and inspection. A printed pattern is not proof of a sound casting. Treat manufacturer data as scoped process guidance and qualify the full foundry route with the responsible supplier and operator.
EGGSHELL-AMB 10 is deliberately brittle because it is intended as a sacrificial shell for silicone tooling. The relevant workflow includes drainage, cleaning, shell removal, silicone chemistry, inhibition risk, mold fill, venting, surface transfer and final silicone-part inspection. It is a poor choice for a durable direct-use part precisely because its useful job is to break away.
Manual feed makes changeover a controlled operation
The product page describes quick material changeover and a manual material feed, with separate units available for cleaning, drying and curing. Translate that promise into a written procedure. Record the machine, software and profile version, resin SKU and lot, container state, tray or membrane state, orientation, supports, layer setting, print record, wash chemistry and time, dry endpoint, cure unit and cycle, finishing and inspection. Keep the traveler with the part when repeatability matters.
Do not pour recovered material into a new container unless the current manufacturer procedure explicitly allows it and the identity and contamination controls are preserved. Respect shelf life, storage temperature, mixing and filtration instructions. Inspect the tray and platform between materials, use designated tools where required, and define a restart coupon or part check proportionate to the risk. "Quick" is not the same as "control-free."
Actual output depends on geometry, layer settings, nesting, resin, supports, failures, changeovers, washing, drying, curing, labor and inspection. The product page's speed and repeatability claims have stated test conditions; they are not a guaranteed customer throughput, tolerance or quote. Build the purchase decision from representative jobs and the complete post-processing bottleneck.
Resin, solvent, UV and facility safety boundaries
Uncured photopolymer, contaminated tools and wash liquid require chemical controls. Follow the current 3D Systems operating instructions and the exact resin safety data sheet for gloves, eye and skin protection, ventilation, storage, incompatibilities, spill response and disposal. Keep food and drink out of the work area, cover resin when it is not being handled, and do not send uncured residue or contaminated wash liquid to a sink.
Washing may introduce flammable or otherwise hazardous solvents. Use only approved chemistry and listed equipment, control ignition sources, store containers as required, and follow local fire-code and waste rules. UV post-curing adds optical, electrical and heat hazards; keep interlocks and shielding intact. Review ventilation, electrical service, fire controls, access, housekeeping and emergency response for the entire installation, not just the printer footprint.
The NIOSH safe-3D-printing guidance supports source control, ventilation and exposure reduction as a hierarchy. It does not replace the resin SDS, equipment manual, industrial-hygiene review, fire authority, electrical requirements or local environmental rules. GoodPrints is not the final safety authority for this installation.
Never handle uncured resin as though the cured part's marketing category applies to the liquid. Gloves need compatibility with the exact resin and wash chemistry plus a replacement schedule. Cure and wash waste, absorbents, filters, supports and failed parts may require controlled disposal. Medical, food-contact, electrical, flame-rated, pressure, lifting, vehicle-control and other regulated uses need responsible application and compliance approval.
Buyer and owner decision
- Choose Figure 4 Standalone when low-volume prototyping or production repeatedly fits the 23 current exact-machine resins and manual feed plus separate post-processing match the operating model.
- Choose by failure mode, then lock the exact SKU, profile, wash and cure process instead of picking the strongest-sounding material name.
- Pause for written confirmation when a quote depends on regional availability, a package format, a newly listed formulation, a regulated claim or a material absent from the exact finder.
- Choose Figure 4 Modular or Production when dedicated engines, automated delivery, scheduling and centralized finishing are more important than a compact manual-feed workflow.
- Consider the Figure 4 135 material route or Formlabs Form 4L guide when their released materials, build envelope and workflow better fit the job.
- Outsource first when demand is intermittent or the team does not want to own chemical handling, washing, drying, curing, ventilation, waste, records and part qualification.
For a defined part, use the material-selection checklist, review the custom-printing service FAQ, request a GoodPrints quote, or use the JC Print Farm route when external production fits better than owning the process.
Bottom line
The defensible current starting set is the 23 materials in the live Figure 4 Standalone finder. Use that list to shortlist a resin, then lock the exact SKU and lot, released 3D Sprint profile, manual-feed and tray procedure, changeover, washing, drying, cure, facility controls, traceability and finished-part evidence. Broader portfolio membership, 405 nm language and apparent cure are not substitutes for an exact-machine release.
