that will produce high quality, functional parts, using an accurate and repeatable FFF print process, at low
cost per part.
TRAK 3ntr 3D Printers offer:
•An open materials platform enabling selection of a wide range of materials
•Complete flexibility in tailoring/tuning process settings and part characteristics
•Temperature controlled build chambers and printer plates
oNozzles up to 840° F (450°C)
oBed Up to 320° F (160° C)
oChamber up to 194° F (90° C)
•Generous build capacity/volume
oPrint Parts up to 24”x13”x19” for the A2
oPrint Parts up to 12”x7.5”x 8” for the A4
•Simultaneously prints 2 or 3 different print materials
•Integrated camera offering remote web monitoring
•Optional Material Management System to protect expensive environmentally sensitive materials
•KISSlicer software that converts STL files to printer ready g-code programs
•HEPA Filter
1.1 Printer Guide Overview
This Printer Guide covers the following topics:
•Initial printer installation, connection, set-up, and calibrations
•Operating the printer manually from the LCD front panel
•Everyday operating, print job set-up, & maintenance procedures
•Before you print
•Printing parts
•Calibrating the printer
•Maintaining the printer
•Troubleshooting machine/print problems
•Some basic information about print materials
Programming of the TRAK 3ntr 3D printers is not covered within this Printer Guide because programming
is performed with separate slicing software that outputs a printer program file (G-code). The TRAK 3ntr
is supplied with KISSlicer software and associated reference files necessary to make G-Code files for
printing, please consult the appropriate manuals for that software in order to create G-code files for
printing.
NOTE - Despite the best efforts for completeness, the scope and detail of the Printer Guide set-up,
calibration, operation, and maintenance manual contents can be somewhat limited. Where additional
information is required please consult the appropriate manual or contact your dealer.

2Safety
The safe set-up, calibration, and operation of your TRAK 3ntr 3D printer depends on its proper use and
precautions taken by each operator. If these activities are performed incorrectly, there are risks, not
limited to, electric shock, pinch/crush, burns, inhalation of fumes/debris that can cause serious injury or
death.
Read and follow this Quick Start Guide. Understand the printer operation and safety precautions before
setting up, calibrating, or operating the 3D printer.
•Always wear safety glasses, face mask, and safety shoes.
•Always stop the printer before opening the access door and reaching into the printer.
•Always allow the printer, printer surface plate and workpiece to cool adequately before reaching
into the printer.
•Have a qualified electrician make all electrical connections and cable wiring
•Never wear gloves, rings, watches, long sleeves, neckties, jewelry, or other loose items when
operating the printer.
2.1 Important Safety Notice
Your printer has been built with user safety as main concern, yet it must NOT be used by individuals with
reduced mental or physical abilities. This printer is not a toy, is meant to be used by fully responsible and
knowledgeable people and printing area must be kept locked in presence of children or people with
serious mental problems.
2.2 Safety Issues to be Considered
Risk of burns
Hot surfaces are involved into the printing process. To
minimize risks, be sure not to access any part inside the
printing area while printer is working. Once printing
process is finished, wait until printed part(s) cool down
to room temperature, or use protective gear (gloves) to
remove finished prints.
Risk of pinching:
Machine can suddenly start: even if the power of
actuators is low, the speed is high enough to hurt. Don't
access machine until printing process isn't completed -
or- the machine is remotely actuated (i.e.: using a print
server).
Risk of fire:
Don't turn on printer close to flammable substances.
Don't use any flammable substance to clean the
machine inner parts. Do not use printer without
supplied removable print tray. Do not use any spray
product inside printer. Allow correct printer ventilation:
don't obstruct air inlets and outlets, keeping them free
from dust and other contaminants.

5
TRAK Machine Tools
Southwestern Industries, Inc.
TRAK 3ntr 3D Printers –Printer & MMS Guide
Risk of toxic fumes:
Wrong temperature settings may cause toxic fumes
emissions. Be sure to follow guidelines and settings
from supplier of your filament. Use printer in a well
vented room. If possible, use machine smoke exhaust
port: our F1 filtering unit is available –contact us to
know more!
Electrocution Risk:
Do not use in presence of condensing moisture and/or
conductive dusts. Disconnect AC power cord before
accessing inner parts. Do not attempt any maintenance
work on electric or electromechanical parts. Should you
notice any electrical malfunctioning immediately stop
machine use and report.
Electromagnetic Interference
Electromagnetic compliance: this is a class A product. In
a domestic environment this product may cause radio
interference in which case the user may be required to
take adequate measures.
2.3 Safety Precautions
1) Do not operate this machine before the TRAK 3ntr Safety, Installation, Maintenance, Service and
Parts List Manual, and the Safety, Programming, Operating & Care Manual have been studied and
understood.
2) Do not run this machine without knowing the function of every control key, button, knob, or
handle. Ask your supervisor or a qualified instructor for help when needed.
3) Protect your eyes. Wear approved safety glasses (with side shields) at all times.
4) Allow the machine to cool before reaching into it for any reason. The printer bed, printer surface
plate, printed part, extruders/nozzles, and other printer interior components can reach very high
temperatures and cause serious burns.
5) Don't get caught in moving parts. Before operating this machine remove all jewelry including
watches and rings, neckties, and any loose-fitting clothing.
6) Keep your hair away from moving parts. Wear adequate safety headgear.
7) Protect your feet. Wear safety shoes with oil-resistant, anti-skid soles, and steel toes.
8) Take off gloves before you start the machine. Gloves are easily caught in moving parts.
9) Remove all tools (wrenches, check keys, etc.) from the machine before you start. Loose items
can become dangerous flying projectiles.
10) Never operate a 3D printer after consuming alcoholic beverages, or taking strong medication, or
while using non-prescription drugs.
11) Protect your hands. Stop the printer bed movement and extruder translation mechanism:
a. Before opening the printer access door
b. Before reaching into the machine for any reason
c. Before changing parts
d. Before removing the printer bed tray, printed parts, or filament debris
e. Before you make an adjustment to the extruder, nozzles or any interior mechanism.
12) Protect your eyes and the machine as well. Don't use a compressed air hose to remove the
debris or clean the machine.
13) Keep work area well lighted. Ask for additional light if needed.
14) Do not lean on the machine while it is running.

TRAK 3ntr 3D Printers –Printer & MMS Guide
15) Prevent slippage. Keep the work area dry and clean. Remove obstacles of any kind around the
machine.
16) Avoid getting pinched in places where the printer bed or extruder arm movement can cause a
crush or pinch injury
17) Do not operate the printer with the printer access door open or any of the windows or service
access panels removed.

5Initial Printer Installation, Set-Up & Calibration
Before your TRAK 3ntr A2/A4 printer is ready to 3D print parts, it must be properly installed, set-up, and
calibrated. Factory Trained personnel should have performed and completed this entire process after
delivery; however, the instructions are provided within this guide in the event the printer is to be
shipped/moved to a new location after the initial set-up.
Procedure instructions unique to the initial installation Set-Up & Calibration (not used elsewhere) are
contained within this section. Those procedure instructions common to both initial Set-Up and Calibration
and other printer use are only listed within this Section; however, the procedure instruction details reside
in the other sections of the guide with hyperlinks to allow easy access.
NOTE - Those new to the TRAK 3ntr A2/A4 printers may find using the separate, dedicated set-up
document TRAK3ntr A2 A4 Printer & MMS –Set-Up and Calibration Quick Start Guide faster and easier
than using this guide for new printer installations because it has all the procedures presented in a step-
step process for beginners.
5.1 Initial Printer Set-Up & Calibration Checklist
Follow the checklist when installing a new printer and applicable items any time the printer is physically
moved from its resting position on the printer stand/MMS Unit.
