3D Printing

- Thursday nights are 3D Thursdays! Visit us from 7 p.m. onwards on Thursday nights.. Whether you just want to learn how to print, have some objects or designs in mind for printing, or just want to use our printers, feel free to drop in and give it a try. If you do have specific models in mind, it would be a good idea to check if they are printable first, as some models will print better than others. Please direct model enquiries to info@hackmanhattan.com.

We have several 3D printers in use at the space:

- Guan loaned his Prusa Mendel V2, to the space. It can print in PLA or ABS, but we prefer you use PLA if possible. There are instructions on how to use it here

- Rob bought an Ultimaker and loaned it to the space. This printer works very well, producing nice prints and is reliable.

- The excellent Brook Drumm of Printrbot donated a number of Printrbots to the space, which can be used by visitors. One of the Printrbot Jr printers is hosted on a Raspberry Pi running Octoprint, with CuraEngine slicer integration. Login to it using the IP address printed on the side of the printer, and upload an STL!

- We built and modified several Wallace Repraps.

- We also run classes on how to build your very own Printrbot Simple 3D Printer.

- We have a list of 3D printing resources and 3D Projects that have been done at HM.

- There are several ways to do 3D Scanning of objects at HM.


Ultimaker

The following attachment contains the ini file with optimal settings to be used with the ultimaker original at HM.

Procedures

Plug the power brick attached to the fans under the ultimaker before you start printing. Failure to do so will result in broken print jobs. Before the sd card slot seems to unseat during long prints with frequent vibrations, a raspberry pi with Octoprint was connected to the ultimaker. Load the gcode from octoprint to start the print job.

Default x,y steps: 78.74 78.74 New values: 79.50 79.53

Octoprint

CTC

The black 3d printer located on the left of the ultimaker. It can only print using .x3g files. The space desktop has an installation of Simplify3D that's able to generate the files. The printer files should be transferred via SD Card.
