One of two core structural elements in the MATRIX 3D Build System, beams are distinguished by their gold color. They come in variety of lengths and are available in two styles: L Beams and Flat Beams.
L-Beams: Used as primary structural
elements where strength is required.
Flat Beams: Good for low stress support
structures or as a spacer.
Joiners are the other basic element in the MATRIX building system and are important to creating well engineered structures. Joiners are silver and designed to fit inside L beams. There are 3 types of Joiners each with its own
designated role in creating different parts of a structure: Straight Joiners, 2D Joiners, and 3D Joiners.
Straight Joiner: Used to attach two
L-Beams together in a straight
2D Joiner: Used to attach two
L-Beams together at right angles.
3D Joiner: Used to attach L-Beams
along X, Y, and Z coordinates.
The following are examples of how L-Beams connect to each type of joiner. Note the hole pattern used for the screws. This assures that there is enough space for the nuts on the inside of the joiner.
There are two types of plates: Gusset Plates & Flanged Plates
Gusset Plates: Gussets can be attached
between two beams to add structural
integrity to your build. They also make great
hosts for controllers, sensors and battery
Flanged Plates: Flanged Plates come in two
varieties long and short. They’re good for
structural braces and gear boxes.
There are two types of fasteners in the MATRIX 3D Build System, Quick Connectors for quickly prototyping your designs and Hex Nuts for use when you want to commit to your build.
Quick Connector – Short: Use to
connect 2 pieces of metal
Quick Connector – Medium: Use
to connect three pieces of metal
Quick Connector – Long: Use to go t
hrough a LEGO® beam and a
Standard Hex Nut: Use in low
Hex Nut w/Toothed Washer: Use
in high stress instances.
Hex Nut w/Nylon Lock Insert: Best
used when attaching plastic to
