Rostock MAX's Cheapskate design uses t-slot aluminum extrusion as not only the structural member, but also the linear bearing surface.  To keep the bearings from wearing the aluminum's surface we CNC machine acetal bearing covers.  ALL Rostock MAX kits now come with our new EZStruder, set up for 1.75mm filament.  The hot-end platform as well as the Delta arms are all made from incredibly strong, lightweight injection molded reinforced plastic.  The same material is also used in the extruder body to keep everything super strong and light.  The wood kit's laser cut framework uses a new material introduced to 3D printers by us, melamine laminate.  It's easier to work with, and more durable than other laser cut plywoods that are popular.  The laser cut parts speed up assembly of the printer and help key the major parts together while you install the hardware.  The extruder features an integrated spool holder designed for 1lb. or 2.2lb (1kg.) spools. 

  Take a look at the standard features below:


• Over 1300 in² of build volume (11" Diameter by over 14 3/4" height) 

• Your model is stationary throughout the entire build process, less prone to print failures

• High quality Laer cut, Injection molded and CNC machined parts all made by us right here in the USA

• Comes set up for 1.75mm filament 

• Uses high torque NEMA 17 stepper motors

• Comes standard with a .5mm nozzle for easy printing, but can use our other sizes as well

• 450w PSU delivers more than enough power for the heated bed, hot end and accessories you could add

• RAMBo by UltiMachine electronics

• Positioning accuracy of .02mm (20 microns) *

• Speed in excess of 300mm/s in all motion, not just X/Y moves ***

• Tinker-friendly electronics and hardware.  Many extra places to add your own mods to both

• Filament spool holder incorporated into the machine (for 1lb or 1kg spools only)

• Easily upgradeable to dual-extrusion in the future.  RAMBo supports dual hotends and extruders stock


This kit includes the following:


• All Laser cut parts and pieces to build the entire machine

• T-SLot aluminum extrusion pre-cut to length

• All hardware (stainless where applicable) to build the entire machine

• NEW EZStruder extruder

• Our own Hot-end, set up for 1.75mm filament

• All 4 NEMA 17 stepper motors

• NOW INCLUDES LCD Controller, for standalone prints!

• RAMBo Electronics by UltiMachine, including 3 mechanical endstops and all wiring ****

• 450w ATX PC style power supply for powering the machine

• Onyx Heated Bed


Here's what you will need to complete the assembly:


• Appx. 15hrs. to fully assemble and wire the complete machine

• Standard Allen wrench set

• Needle nose or small pliers

• Wire crimping tool or solder and solder iron

• Standard and Phillips Screwdrivers

• High Temp RTV silicone for retaining heating resistors/thermistor in hot-end, or Hight Temp expoxy


The overall machine dimensions are approximately 18" in diameter by 42" tall

*   Positioning accuracy is calculated at .01875mm for one eight micro step using 15 tooth 2mm pitch GT2 timing belts.  Printing below .1mm layer heights has been done for over a year by many other printers, and may require you to calibrate and adjust the firmware settings.

*** Actual speed will be determined by size/shape of object along with accelaration/jerk settings in firmware

**** Stepper motors, hot end and heated bed will need wires ran to RAMBo, but connectors are included in the kit
