Description
The 1X2 is a Reprap class 3D-printer that can be built with access to only a drill-press and hand-saw. All the parts can be made with one-dimensional tools and straight cuts. Even with these limited requirements, it is designed to be easy to build and have a full set of features.


Features:

  • It has a printable area greater than all of its parts(including the rods).
  • Dual-head extruder and plotter(w/ hot and cold separation).
  • Simultaneous extrusion and plotting.
  • Quick-change plotter head.
  • Extremely narrow x-carriage design.
  • It uses only 608 bearings.
  • It uses only 5/16" bolts.
  • It uses all 1-unit length rods.
  • It uses all DIY belts.
  • Uses all DIY drive pulleys.
  • Uses all DIY couplers.
  • Full conveyor-belt y-axis(reduced parts, high accuracy, low weight, automated ejection, large build area).
  • Adjustable conveyor belt tension with bed height.
  • Conveyor-belt goes to both edges of the machine for end-to-end chaining of machines.
  • Hand-crank for conveyor belt.
  • A single block is capable of building all frame vertex points.
  • A single extended block is used for Nema17 motor mounts, 608 bearing axle supports and pillow-blocks.
  • The 5/16" holes fit both 8mm & 5/16" hardware.
  • Works with variable lengths. The design is not length specific, so you can build a range of
  • machine sizes, from full size to compact with the same pieces.
  • The frame is chainable, you can build a linked multiple segment Longcat machine.
  • It uses only 1"x2" wood for all parts.
  • It uses a 35/77 system, where all the parts are either 35mm or 77mm in length. The parts for the entire system can be cut to length in two fixture setup runs(with a few exceptions).
  • All cuts are 1-dimensional 90 degrees.

Scoop Extruder:

  • Adjustable tension with no pulleys or pusher blocks.
  • The "scoop" extruder uses the PTFE tube itself as the "idle pulley"
  • It uses the Makerbot Mk5 nozzle and hot-end tube.
  • Makergear style geared stepper.
  • Raysyu drive gear.
  • A Nophead style heater block.

Plotter Head: This single pivot floating head plotter arm works consistently over a very wide range of surfaces. The servo actuation provides fast on-off movements. The entire plotter arm and servo can be removed or switched with another pen without taking the pen out of position. The large 5/16" holding nut uses low force and acts as a knob that can be easily spun on/off by hand. The band clamp pen holder can hold just about any pen sized tool.
