1. Introduction
1
Thank you for purchasing a KNP3D! At KNK USA we are committed to providing the very best customer
support for our products.
If you are new to 3D printing, remember that it’s not like using a regular printer. It’s not meant to be fast
and it’s not meant to be used as a production machine. 3D printing is a fabrication process and, with
each print, you are essentially “growing an object.” You will learn about the variables which affect each
print (such as temperature, speed, layer thickness) and you will learn how these variables work in
combination to produce amazing results!
So, let’s get started! Before attempting to operate your KNP3D, please read Chapters 1 –3. It’s
important to get the KNP3D set up properly, the plate leveled, and the proper settings loaded. Take note
of anything marked IMPORTANT or in red type throughout this manual.
1.01 User Manual Options
This is a preliminary user manual and will be greatly expanded in the future. Please check back
regularly for updates.
This user manual is published in three formats: an interactive online manual, a downloadable
interactive manual, and a PDF version. All three contain the same information; the format options are
for your convenience.
The following shows the functions of the various icons in the two interactive versions:
Turning Pages: To turn
pages, click on arrows, enter a page number, click or
swipe on the lower corners of the pages, or click on
triangles on right or left sides of pages.
Enable Full Screen: Click for Full Screen
mode. Press Esc or click on icon to return to regular
mode.
Print: Select pages to print to your printer. It is
recommended that you do not print the entire manual
as it is updated every six months or so.
Bookmark: Table of Contents opens and you can
click on any chapter, section, or subsection to
immediately access.
Thumbnails: Displays the thumbnail images for all
pages in the book.
Sound: Click to turn off or turn back on the
page flipping sound.
Zoom: Zoom in and out, as needed. You can
also double click on a page to zoom in or out. Note
that while zoomed in, moving the mouse automatically
scrolls the page up and down.

1.02 Safety
Please be aware of the following safety guidelines when working with the KNP3D:
Hot Elements: Do not touch the heated build plate or extruder nozzles while the KNP3D is printing.
At the end of the printing process, wait for the printer to cool down before touching the extruder head
or build plate. This can take around 15 to 20 minutes.
Fire Hazard: Do not place flammable materials near the KNP3D.
Pinch Points: Keep hands, long hair, jewelry, etc. away from the moving parts.
Risk to Children and Pets: Please supervise children around the printer while it is heating, as well as
printing. Also note that small printed items could pose a choking hazard to both children and pets,
especially when inadvertently dropped onto the floor.
Eye Protection: When removing support material on finished models, please use safety glasses to
protect your eyes.
Adequate Ventilation: When printing with ABS (acrylonitrile butadiene styrene) filament, a pungent
odor will be emitted. Please operate the KNP3D in a well-ventilated room but avoid any direct air
blowing on the printer as this can interfere with temperature control.
Movement and Touching: Do not move the KNP3D or touch any circuitry while it is plugged in.
Recommended Materials: Only use the recommended filament types sold at www.knp3d.com. If you
are interested in trying a different filament, please contact KNK USA first to determine if the KNP3D is
designed to print that material.
1.03 Warranty
IMPORTANT: If a KNP is damaged during the initial shipment to the customer, then your dealer
should be notified as soon as possible. If damages are reported later than three weeks after delivery,
then it will be the responsibility of the owner to ship the damaged KNP back to KNK USA for repair.
The one year parts and labor warranty covers parts for both accidental damage, as well as wear and
tear. If warranty work is required, the owner is responsible for shipping costs to and from KNK USA.
Discounted shipping will be provided by KNK USA.
KNP3D owners outside the USA should contact their dealer for procedures regarding warranty work
or shipping damage.
It is also recommended that you retain the original box with packing materials in case you ever need
to ship your KNP3D.
1.04 Support
If you need additional assistance after reading this manual, please visit our forum at
http://knkusa.com/forums/. Click on the KLIC-N-Print 3D category listed in the right side menu.
We are also available by filling out a contact form at: http://knp3d.com/contact-us/ or by calling 800-
268-3672.
If you purchased your KNP3D from one of our authorized resellers or distributors, please contact
them as your first line of support.

1.05 Unpacking
When unpacking the KNP3D we recommend placing the box on the floor.
Open the top of the box and remove the cartons that surround the printer.
Next, remove the printer by lifting it by the top metal frame. Do NOT remove the printer by lifting it
by the cables.
Take note that the two boxes at the bottom of the shipping box contain the power cable, USB
cable and the filament guides.
Place the KNP3D on a work surface. A 3D printer should be operated in a dust-free, non-humid
room with a temperature of 65°F (18°C) or warmer. If printing ABS filament, also make sure the
room has adequate ventilation.
Open the box that contains the KNP3D extruder and remove the box from the printer.
The build plate should now be visible. You’ll notice a thin layer of Kapton tape covering the build
plate. Do not remove this film. This is the surface material on which you’ll eventually be printing.
Next, the build plate needs to be raised.
This can be done by manually rotating the large threaded screw clockwise directly behind the
build plate.
Raise the build plate until you can easily access the two boxes beneath which contain spools of
filament. Carefully remove these as well as any remaining packaging.
