Direct answer: the current 3D Systems DMP Factory 350 page names LaserForm Ti Gr1, Ti Gr5, Ti Gr23, AlSi10Mg, AlSi7Mg0.6, Ni625, Ni718 and 316L, plus Certified Scalmalloy and Certified M789, as commonly used materials. Its exact-model brochure documents a broader single-laser list that also includes A6061-RAM2, CuCr2.4, tungsten, CuCr1Zr, HX, CuNi30 and C-103; it marks GRX-810 as evaluation-only through 3D Systems' Application Innovation Group in the United States.
There is an important current documentation conflict. The page calls the Factory 350 a single-laser machine, but its technical table says “2 x 500W” and labels the alloy list for dual-laser configurations. The exact-model brochure says “1 x 500W” and calls the same broad list single-laser options. Do not resolve that conflict from marketing copy: obtain written confirmation for the exact serial number, hardware configuration, setup, removable print module and released 3DXpert parameter set before approving a material.
DMP Factory 350 material compatibility at a glance
| Material lane | Verdict | Decision boundary |
|---|---|---|
| Ti Gr1, Ti Gr5 and Ti Gr23 | Current commonly used routes | The brochure assigns these to Setup A. Confirm exact powder, parameters, oxygen control and the regulated-use qualification. |
| AlSi10Mg and AlSi7Mg0.6 | Current commonly used routes | Both are documented; choose by the required material state and qualified property evidence, not by the word aluminum. |
| Ni625, Ni718 and 316L | Current commonly used routes | The alloy name does not approve pressure, flight, implant, food-contact or high-temperature service. |
| Scalmalloy and M789 | Current commonly used routes | Require the current certified powder identity, Setup B where applicable, heat treatment and acceptance plan. |
| A6061-RAM2, CuCr2.4, CuCr1Zr, HX, CuNi30 and C-103 | Exact-brochure route; configuration confirmation required | The brochure lists them for the single-laser Factory 350, but the live technical table is internally inconsistent. Get the released route in writing. |
| Certified Tungsten | Exact-brochure route; specialist controls required | Confirm Setup A, powder handling, parameter release, geometry limits, post-processing and exposure controls. |
| GRX-810 | Evaluation-only in the current brochure | Do not represent it as a normal production material route; the brochure limits it to evaluation through AIG Services in the United States. |
| Generic third-party, recycled or custom powder | Unsupported or poor fit by default | Nominal chemistry does not establish flow, particle distribution, oxygen history, parameters, safety or finished properties. |
| Polymers, bound-metal filament, wire, pellets, resin or paste | Different process | Choose equipment designed for that feedstock and its downstream workflow. |
The live page and brochure must be reconciled before purchase
The exact product page describes a midsize single-laser system, integrated powder handling and automatic sieving, a 275 × 275 × 420 mm build volume inclusive of the plate, a soft-blade recoater, glove-port access, a vacuum chamber intended to maintain less than 25 ppm oxygen and argon flow. Yet the same page's technical table says two 500 W fiber lasers and calls the broad alloy list “options for dual laser configurations.”
The linked DMP Factory 350 brochure instead specifies one 500 W fiber laser and labels the broad list for single-laser configurations. This is not a cosmetic wording issue: laser count, optical layout, setup, software release and parameter database can determine whether a material route is actually released. Ask the seller or 3D Systems to identify the exact model designation, serial/configuration, Setup A or B, RPM, powder part number, 3DXpert version and supported parameter set in the quote and acceptance record.
Do not transfer capabilities from the DMP Factory 350 Dual or the DMP Flex 350 Triple material route. Their names share a platform family, but that does not prove identical laser exposure, powder workflow, monitoring, options or qualification.
Titanium routes need oxygen, powder and application control
LaserForm Ti Gr1, Ti Gr5 and Ti Gr23 appear in the commonly used section and the exact brochure. The brochure marks them as Setup A. That establishes a current manufacturer route, not universal interchangeability. Gr1, Gr5 and Gr23 serve different chemistry and property requirements, and lower interstitial limits or biocompatibility positioning must be tied to the exact powder, build, heat treatment, surface state and applicable test record.
Titanium powder sharpens combustible-powder, contamination and oxygen-control risks. Receiving, storage, loading, sieving, sampling, depowdering, filter service, spill response and waste handling need the current safety data sheet, manufacturer procedure and site assessment. A part intended for medical, aerospace, pressure or other high-consequence service requires its governing qualification; a brochure's application examples are not approvals.
Aluminum routes are not one generic material choice
LaserForm AlSi10Mg and AlSi7Mg0.6 are current commonly used routes. Certified Scalmalloy is also named, while Certified A6061-RAM2 appears in the broader exact-brochure list. Choose among them from the drawing and service need: required material condition, strength, elongation, fatigue, corrosion, thermal performance, heat treatment, machining and joining. Do not copy a wrought, cast or differently processed grade's values onto the printed part.
A6061-RAM2 especially needs the configuration gate because it is not in the page's shorter commonly used section and the live technical table is mislabeled for a different laser configuration. Require the current powder identity, parameter release, post-treatment route and representative acceptance data. Similar base chemistry does not make it equivalent to conventional 6061.
Nickel, stainless and tool-steel routes need end-use evidence
LaserForm Ni625, Ni718 and 316L are commonly used on the exact page. Certified HX and M789 are also documented, with M789 in the commonly used group and HX in the broad brochure list. These names can make the system relevant to corrosion, heat and tooling work, but they do not establish fatigue life, creep, pressure-code compliance, sterilization, passivation or suitability for a specific chemical environment.
State the required as-built or post-processed condition. Support strategy, residual stress, stress relief, hot-isostatic pressing, heat treatment, machining, polishing and inspection may control the result. Put critical holes, sealing faces, threads, datums and internal channels on an explicit finishing and metrology plan. The manufacturer's repeatability and typical-accuracy figures are scoped system claims, not a tolerance guarantee for every alloy, feature and build location.
Copper alloys, tungsten and C-103 are specialist decisions
The exact-model brochure lists CuCr2.4, CuCr1Zr, CuNi30, Certified Tungsten and C-103. Their presence is useful evidence, but a buyer still needs the exact released build style and application route. Reflectivity, thermal transport, density, contamination, recoating, support removal and post-processing differ materially across these feedstocks. Laser power or melting point alone cannot prove compatibility.
Define conductivity, temperature, corrosion medium, radiation or shielding need, mass, surface, internal-channel cleanliness and inspection method before choosing a grade. Tungsten and refractory-alloy work may create demanding powder, machining and waste controls; copper-alloy performance depends on the specified condition. Manufacturer data remains a claim with defined samples and conditions, not independent testing of the customer's geometry.
Integrated powder management does not remove powder responsibility
The Factory 350's integrated handling and automatic sieving can reduce open transfers, but “integrated” does not mean exposure-free or qualification-free. Each powder change needs the approved cleaning, segregation and verification procedure, compatible conductive tooling, labeled containers and powder-history records. A removable print module can help changeover; it does not erase cross-contamination risk in shared handling, sieving, filters, accessories or the room.
Track supplier and lot, virgin and recovered fractions, exposure history, sieving, sampling, storage, oxygen or moisture controls, refresh rules and disposal according to the qualified route. Do not invent a universal recycle count from a powder-recyclability claim. The usable lifecycle belongs to the exact alloy, process, quality system and acceptance evidence.
Argon, laser, electrical, ventilation and fire boundaries
This is industrial metal-powder and Class 4 laser equipment inside an engineered enclosure, not a desktop appliance. Install and operate it under current 3D Systems site-preparation, operating, maintenance and safety instructions; local electrical, fire, ventilation and building rules; and a site-specific risk assessment. Preserve interlocks, guarding, grounding and bonding. Do not bypass the enclosure or improvise service work.
Fine metal powders can create inhalation, skin, eye, contamination, combustible-dust and reactive-metal hazards. Argon can displace oxygen. Soot, condensate, used filters and cleanup material remain process waste. Use manufacturer-approved closed handling, compatible conductive equipment and vacuuming, housekeeping, PPE, oxygen monitoring where required, and fire controls selected with the manufacturer and local fire authority. Water or an ordinary extinguisher can be wrong for some metal-powder fires.
Ventilation must control the tasks identified by the current SDS and risk assessment, including loading, sampling, depowdering, sieving, filter changes, cleanup and maintenance. NIOSH's safe 3D-printing guidance supplies a useful control framework, but it does not replace 3D Systems instructions, alloy-specific SDS documents, an industrial hygienist, the fire authority or the responsible safety organization.
Unsupported feedstocks and better-fit platforms
Do not treat the 3D Systems metal catalog or material finder as proof that every portfolio grade runs on the Factory 350. A material may belong to another DMP machine, setup, laser configuration or application package. Cobalt chrome, 17-4PH, maraging steel, precious metals and other grades remain confirmation-required unless current exact-machine documentation supplies the complete route.
Bound-metal filament belongs to a print, wash and sinter system such as the Markforged Metal X. Continuous-fiber composite belongs to equipment such as the Markforged FX10. High-temperature thermoplastic belongs to a polymer platform such as the AON3D Hylo. Choose by feedstock and complete workflow, not by the generic phrase “industrial 3D printer.”
Finished-part claims need their own qualification
Preserve traceability for the machine and RPM, calibration and maintenance state, software and parameter version, powder lot and history, build plate, atmosphere record, orientation, supports, heat treatment, HIP, machining, surface processing and inspection. Product-page application examples and material descriptions do not certify a customer's component.
Pressure, lifting, flight, vehicle-control, medical, dental, food-contact, electrical, fire-rated and other high-consequence uses require their applicable standards and responsible approval. Qualify representative parts and the real assembly. Internal porosity, lack of fusion, residual stress, surface condition, thin walls, channels, notches, threads and joining can govern sooner than a brochure value.
Buyer and owner decision
- Choose the DMP Factory 350 when a currently documented alloy and recurring part family justify a qualified LPBF cell, and the organization can own powder, argon, safety, post-processing, inspection and quality records.
- Start with a commonly used exact-page route and obtain the current datasheet, exact setup and released build style.
- Pause for written configuration confirmation because the live page and exact brochure disagree on laser count and the live table's configuration label.
- Treat GRX-810 as evaluation-only under the current brochure, not as an ordinary production material.
- Choose a different process for polymer, continuous fiber, bound-metal filament, wire, pellets, resin, paste or an unqualified custom powder.
- Outsource first when demand is intermittent or the team does not already own industrial powder handling, inert gas, fire controls, post-processing, metrology and quality responsibility.
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 is a better fit than owning this cell.
Bottom line
The DMP Factory 350 has a substantial current manufacturer-documented alloy route, led by titanium, aluminum, nickel, 316L, Scalmalloy and M789. The brochure adds several specialist grades, but the live page and brochure currently conflict about laser configuration. Make exact-machine, setup, RPM and parameter confirmation the first gate; then qualify powder, atmosphere, safety, post-processing and the finished part. Buy the system for a controlled production route, not for a theoretical list of metals its laser could melt.
