The Beginning

Being interested in 3D printers since 2011 after purchasing a
BFB 3D Touch (Now 3D Systems with the latest model being the Cube Pro costing over £2000) I wanted to build a stable Large build platform 3D Printer for a fraction of the price.
Many Enthusiast's entries into the 3D printer market comes from the purchase of the Prusa i3 kit and in keeping with the good work of the Joseph Prusa design I felt it would be great if the design could be simple.
One of the many drawbacks I noticed was the overall finished look of the DIY kits; i set upon the task of creating a product that not only was affordable and easy to build but one which had style and form a look in keeping with the futuristic possibilities 3D printing brings.

Step 1: About the Printtable




Inspiration to create a 3D printer from an Ikea Lack table simply came from the fact that my BFB 3D touch printer had been placed on top of a lack table for the last 5 years. Whilst the lack table absorbed the vibration and forces applied from 5 years of printing the table showed no obvious signs of wear or distortion. Further investigation of the Lack range fuelled my ambition by the world having easy access to IKEA furniture chain, resulting in a worldwide common platform in which to build the range of large format printers.

It’s this Format which will bring the greatest benefits to Hackers, Builders and 3D printing enthusiasts all around the world encouraging people to build, share and adapt the design creating an entire collaboration of adaptions, improvement's and opportunities. This project was published on 3dhubs.com and as gained such amazing feedback and support with the community requesting a instructable, so here it is for all to use and hopefully you will find it easy to follow with help and support available at the newly created site especially for this project printtable.com
The Printtable project could not of been possible without the amazing help of my family, Louise (my daughter) for burning the candles at both ends creating fantastic renders, schematics for the build instructions and endless contributions to the design, Louise's husband Steve (Son-in Law) who spent hours on social media and websites promoting the Printtable project. My son James who spent most of his spare time just after finishing exams at university to create the website and endless hours (many through the night)piecing together 100s Gb of video footage to create the You Tube follow and build videos (if I had presented before I am sure without all the mistakes we could of done them quicker, Sorry my bad) and finally my wife who had the misfortune of listening to all the debates a family would naturally have when a project means so much to them and the missed nights of snuggling up before we sleep.
For them I want to give special thanks and this personal thank you, your help and support is appreciated and with an amazing family we can create amazing things. Thanks and love you all.
Thanks for reading and have fun creating your own Printtable.

Step 2: How to Access Information? / Creating a Community
At the time of writing this instructable we are still putting the finishing touches to the website Printtable.com.
With-in the site will be links to the you tube channel as well as additional information about the build, we will be giving away some of the build parts such as acrylic panel sets, rods, wiring  and starter kits to builders in competitions and will also provide a one stop shop for all the printable components and upgrades.
A forum for all to assist each other in all thing Printtable and 3d printing.
News articles, tips and tricks and expanding on the printtable plans with help of the community for the future.

Step 4: STL Files For Download

Download the STL files.
Some parts are printed in two halves and require placing together and a hot solder gun run along the joint to weld them together.
Please refer to schematic drawings and pre thread/drill holes which require fixing with M3/M4/M5 bolts or Grub Screws.
8mm and 10mm rod holes may want drilling out and it is recommended to use a masonry drill bit fro this purpose.
Note X Axis Puller wheel Holder as a smaller centre than Y Axis Pulley Holders.
Supports have been marked with position to be placed ensure the wider lip is positioned against the table legs and the thinner lip against the table top.
