This is a steel frame improved design for Anet A8 3D printer.
Version 1.1 code name Hayabusa is out, beginning January 2018, if you want to laser cut maybe you want newer version. -> https://www.thingiverse.com/thing:2736479
(For A6 Version go here: https://www.thingiverse.com/thing:2693658)
My self and Tommaso Collini (https://www.thingiverse.com/musta/about) we tried to implement easy solution to solve common issue we found on Anet A8 printer and most of cartesian printers. We believe Tatara frame is the best steel frame you can build.
In our design all parts are inter locked that ensure great stiffness and perfect geometry on all 3 dimensions.
What is special in our design:
- XY frame to make all build more rigid, this is a major improvement against all others Cartesian Steel frame that let you push printing speed to 150-180mm/sec, 20-25mm/sec2 jerk 1200 mm/sec2 print acceleration with good quality
- We add the option to add 6 LEVEL FOOT to level the printer
- Nyloc/Lock nuts compatible by design
- many small improvement that make the frame incredible rigid with virtual no resonance during printing.
- Damn heavy, more than 9Kg only for frame. Because we are not overseas seller's weight is not a problem but a feature:
-lower center of gravity
-weight leads to a higher inertia and therefore less high-frequency vibration
Steel is the material that gives the best ratio stiffness (young's modulus) vs cost/volume.
To achieve same stiffness with other materials you need to use, at least, a sheet 3 time thicker.
To be manufactured of carbon steel (requires painting) or stainless steel.
We strongly suggest the use of a material with a minimum Young Modulus of 196 GPa ( double check it before you get your frame cut).
Is designed for 3mm thickness (clearance is 3.2mm so maybe you can also use 1/8"-> 3.175mm but we did not try)
people who sell Tatara frame on internet don't give any % to the designers (us) then if you enjoy the Tatara frame ( or if you make money with it)
can be kind to TIP
All measurement are the same as Anet A8 and you have to change only the frame and maybe the screws (depend what length of screw you get on your original Anet A8).
The design will be under CC attribution share alike license 4.0 (https://creativecommons.org/licenses/by-sa/4.0/) as well the DXF laser cut draw.
The draw is done from scratch, by your humble servant.
The first prototype of the Tatara - Anet A8 Steel Frame as been tested by Steve DellaRosa.
Grazie mille Steve!!!
Since then more than hundreds users swap to Tatara A8 steel and push their 3D printing quality and speed to unknow frontiers.
Many users also decide to build a 3D printer from scratch using Tarara A8 Steel Frame.
This is to consider final version, if you decide to laser cut is at your own risk we don't give any guaranties.
ATTENTION: Maybe your laser cut service need to do the nesting and bridging for optimization.
We recommend laser cut service who can provide h7 tolerance cut, watch out some laser cut service do very very low grade cut.
You have 2 version of files: only essential pieces (are excluded: screen part, fix Y belt holder, Z end-stop holder) and standard version with all pieces.
with stock Mother Board and stock firmware Y 0 is 5mm inside the heated bed,
refer here to correct the problem:
3D printed (needed or not) parts can be found (on my buddy account) here: https://www.thingiverse.com/thing:2358104
Extra Precision Rods locker (Y and Z axis) for V1.00 can be found here:
Customizable spacer rear Y motor Holder to Nema 17 motor for Tatara steel frame V100 can be found here;

You can find the sheet with detailed screws numbering <-> part-list, here https://issuu.com/tatarasteelframe/docs/tatara_steel_a8_v100_-_parts_list
Or download the PDF file with the screws and nuts list.
V100b: final version before move to version 1.10, just clean up .DWG files
V100: small mod on X/Y Frame for cable pass through,
RC2 v04: mod Y front and back frame
### REMEMBER TO "Electrical Grounding" the steel frame !!!!!! ###
About the name: Tatara is the name of the forge where the steel for japanese sword is melted.

Find a good Laser cut service, tolerance are important.
