Description:

The 1X2 and 1X2 Tallcat are Reprap class 3D-printers that can be built with access to only a drill-press and hand-saw. The parts for the entire system can be made with one-dimensional tools, straight cuts and common materials.

This machine is made by: mrkimrobotics.com


Status Summary:

Working Status:
The 608 linear bearing system works well and is mature.
The shaft-couplers for leadscrews and axles work well.
The 1X2 vertex frame system has worked well.
The Scoop Extruder has printed continuously for many hours with no issue.
The flat belts themselves are strong, efficient and easy to construct.

Experimental Status:
Consistently countering "belt creep" with non-slipping elastic flat-belts in open-loop control as a function of speed remains an issue of study.


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.
  • 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.
  • One piece x-carriage design
  • One piece extruder design
  • One piece plotter design
  • 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 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.
