INTRODUCTION
Use this guide to help you prepare your facility for the installation of the DMP Flex 350 production printer. Please refer back to
3D Systems InfoCenter for the most up-to-date version of the DMP Flex 350 Facility Guide (p/n: 15-D99).
As you satisfy the requirements for each section in this guide, you need to complete the Facility Requirements Checklist, to
be found in §16.2 of this document. The customer must complete this checklist and send it to 3D Systems when you are
ready to have your equipment installed.
All contact information for 3D Systems service and support is available in chapter 17.
1.1 Limitations of Warranty and Liability
This information is provided by 3D Systems for the convenience of its customers. It is believed to be reliable, but no
be obtained therefrom. The information is based in whole or in large part on laboratory work and does not necessarily indicate
fully responsible for determining which federal, state, or local laws or regulations, or industry practices are relevant to activities
in which it engages, as well as assuring that those laws, regulations, or standards are complied with under actual operating
conditions, and 3D Systems undertakes no responsibility in these areas. In no event will 3D Systems be responsible for damages
of any nature, including special or consequential damages, resulting from the use of or reliance upon this information.
The customer assumes all risk resulting from the use of this information. Customers use of the materials that follow is an
acknowledgment of its agreement to the foregoing. Any customer not wishing to be bound should return this material to 3D
Systems. Nothing contained herein is to be considered as permission, recommendation, nor as an inducement to practice any
patented invention without permission of the patent owner.
1.2 Intended Use
The 3D Systems Direct Metal Printer (DMP) line is designed for the manufacturing of high precision metal parts using 3D
systems approved powders. The printed part properties mentioned in the 3D systems materials datasheet are guaranteed for
corresponding parameters and the instructions as provided by 3D Systems are followed to their full extent where applicable.
1.2.1 Inert Gas Requirement
The printer, its print processes, and the materials intended for use with the printer are designed for operation with a chamber
of argon gas as the inert gas. Argon is a true inert gas that does not react with any metal material during printing, thus
materials are developed with argon as the inert gas.
Any use of an inert gas other than argon, such as nitrogen for example, is at the user’s own risk, and 3D Systems shall not be
responsible in any way for the performance, safety, or part quality when a printer is used with an inert gas other than argon. If
an inert gas other than argon is used, it is the user’s responsibility to ensure the combination of metal material and inert gas is
safe because some materials, for example titanium or aluminum, are reactive with some inert gases, such as nitrogen.
1.2.2 Oxygen Limits
The oxygen limit for running a job on a DMP Factory 350 should be below 225ppm (ppm sensor limit) and 1.98% (% sensor
limit). The DMP Factory 350 system may reach 25ppm during the build process if running with proper consumables as per DMP
Factory 350 Facility Guide & User guide.
