What’s Inside?

This SLS Process User’s Guide includes the

sections summarized below. General safety

guidelines are presented first. The rest of the

Guide is organized in two parts. The first part

covers SLS process procedures and the second

covers SLS equipment.

At the end of this guide, you will also find a

Glossary of SLS process terms and an Index. Click

on any red TLA (three-letter acronym) or

SLS process term in this section to display a

definition.

Safety Guidelines and Instructions

The Safety section tells you what you need to

know to avoid injury or equipment damage. Read

this section before you switch on power to any

SLS equipment or handle DuraForm material.

LTo verify that your facility was properly

prepared for SLS system installation, see the

sPro SLS Process Facility Guide and SLS Process

Facility Layout. For detailed material safety

information, see the DuraForm Material Safety

Data Sheets (MSDS’s). Printed copies of these

documents were included in your SLS powder

material shipment. You can also download

MSDS’s for SLS materials

from3D Systems’ website. (See Other Useful

Documents on page 7.)

SLS Process Procedures

The instructions in these four sections step you

through the SLS process in a general way. When

necessary, they refer you to detailed machine

operating and maintenance instructions in the

equipment section of this guide.

SLS Process - overview of the SLS process from

powder to parts.

Build Preparation - how to prepare 3-D parts for

building using the SLS system’s Build Setup

software; how to clean, power-up, and start-up

SLS equipment, and perform pre-build checks.

LA “build” is a 3-D printout of a build packet

containing STL files of one or more 3-D parts.

You create build packets in the Build Setup

application. See your Build Setup online Help

for detailed build packet setup instructions.

Build Parts – how to run builds on the SLS

system, and how to monitor, control, and modify

a build in progress.

LYou use the Sinter application to run a build.

See your Sinter application online Help for

detailed build instructions.

SLS process 4 ABOUT THIS GUIDE

user’s guide what’s inside?

Breakout Parts – how to remove and cool down

the part cake after a build, then use the BOS to

remove parts from the part cake. This section also

describes how to recycle or dispose of used part

cake powder.

SLS Equipment

This second half of the User’s Guide provides

detailed instructions for the functions you need

to perform on SLS equipment during SLS process

procedures. The process instructions in the first

part of the guide frequently reference equipment

instructions these sections.

SLS Equipment - overview of SLS equipment

featuresand functions. This section includes

illustrations that help you locate SLS equipment

components and controls and convenient menu

maps for the IRS and BOS operator panel

displays.

The four sections after the equipment overview

contain complete safety, operation,

maintenance, and troubleshooting instructions

for each SLS process machine. They focus on the

following:

IRS and IPC - loading powder from the IPC to the

IRS and transferring powder between the IRS,

SLS system, and BOS.

SLS® system - preparing for, and running builds

using the Sinter application and utilities, and

maintaining the SLS system between builds.

BOS - breaking parts out of the part cake and

managing waste and recycled part cake powder.

SLS process 10 SAFETY

user’s guide general safety guidelines

General Safety Guidelines

All SLS equipment is designed with safety in

mind. However, improper use, malfunctions, and

excessive exposure could cause injury.

Follow these general safety guidelines when

operating any SLS equipment:

Training and Instructions

`Do not operate any SLS equipment before

receiving proper training.

`Read and follow all operating instructions.

`Follow all safety rules in this section and heed

all hazard warnings in this guide.

`Do not try to do any equipment maintenance

procedures you were not trained to do.

•Operators are trained to operate the

system and perform all the necessary tasks

to print a part.

•Certified service personnel are those

who have completed the 3D Systems

service training package and are certified

to perform service tasks. Certification may

occur at various levels, and servicers

should only perform tasks they are

authorized and certified to complete.

Machine Handling

`Do not try to access, service, or adjust any

components inside any SLS equipment

enclosure.

`Do not try to open any panel or door while a

machine is running.

`Do not access any area of the machine near

the process chamber high-temperature-

material builds.

`Use special caution when handling a heated

RCM and when dealing with the heated, inert

environment inside the SLS system’s process

chamber. Take note of all thermal hazard

warning labels on the machines.

`Always disconnect the RCM cable before

moving the RCM out of the SLS system or

BOS.

`To prevent crush injuries to the body, use

extra caution when rolling the RCM into and

out of the SLS system and BOS, and when

closing the BOS overhead door. Take note of

all crush hazard warning labels on the

machines.
