Thank you for downloading our Printable Dynetics Human
Landing System model! The following pages will guide you
through the printing and assembly steps.
Remember that dierent 3D printers may need dierent settings
to successfully print more complex parts.
If you experience diculty printing, a variety of resources and
communities on Reddit, Thingiverse, and Facebook can provide
useful information.
Introduction

Material
This model prints best using quality PLA lament, such as
Prusament, Taulman, ColorFabb, and Paramount. Other lament
brands that have also been successfully used include eSun,
HATCHBOX, SUNLU, and AmazonBasics.
PETG is also a viable material, though slightly more challenging.
The printed models shown here are printed in several colors of
PETG.
All model parts are assembled using small amounts of
cyanoacrylate (CA) glue or super-glue.
NOTE: If children will be involved, substitute a child-safe glue.
Print Settings
(Use these settings unless otherwise noted)
Recommended:
• 0.4 mm or smaller nozzle
• 3 perimeter layers
• 30% rectilinear or cubic inll
• Printed with supports
These settings should work on a wide variety of fused lament
printers (e.g. Creality, Prusa, Ultimaker).
The colorful model (shown at bottom on page 7) is printed at
50% model scale. Smaller prints will be especially challenging on
a fused lament printer due to feature size.
A 100% model scale gray model (shown at top on page 7) will t
within the print volume of a Prusa i3 MK3s, the printer used to
make the models shown here.

There are 21 Dynetics HLS parts, plus 16 printed alignment
dowels.
Several elements have been split into multiple parts to simplify
the printing steps.
Depending on your printer, it is possible to set up a single print
that creates several parts at once. For example, all 16 printed
alignment dowels can be arranged into one print.
Similar parts can be printed in pairs when two are needed, since
the settings for those parts are the same.
The red, blue, gold, and teal colored parts in the expanded view
shown here can generally be printed with the same settings.
The following steps will guide you through printing each
element of the Dynetics HLS.

The frame is the most challenging part to print. Once you have
printed this part, you can be condent that you can print all of
the other parts, too.
There are two frame les to choose from:
• One le includes pre-designed supports (the red elements)
for certain parts of the frame. This version can work well for
printing at 50% model scale.
The supports are intended to replace slicer-generated
supports in the “cage”areas on either side of the main
arch. The resulting print can be much more easily freed
from the model supports.
• One le does not include supports. Use this for 100% model
scale prints, or if you prefer to let your slicer generate
supports globally.
It is recommended to use slicer-generated supports for the
center section, as shown by the highlighted section (bottom on
page 11).

The legs are the second-most challenging element to print.
Print two copies of the legs le. Each copy will have two landing
legs joined by some structure.
Recommended print settings:
• 3 perimeter layers
• 100% inll
• Printed without supports
• Printed with a “brim”at the base to reduce part warping and
to eliminate detaching from the build plate during printing

There are two versions of the aft end of the Crew Module:
• One version reads, “Dynetics HLS.”This version prints at any
scale, and is suitable for 50% model scale.
• One version reads, “Dynetics Human Landing System” and is
suitable for 100% model scale. The smaller letters may not
print properly at small print scales.
