Additional opening hours for students

In addition to our opening hours for the Open Lab every Wednesday from 14 p.m. to 20 p.m., this summer term we also have times when the Lab is open specifically for students.
As of now, students can also work in the Fab Lab on Tuesdays and Thursdays during the following times:

Tuesdays from 13 p.m. to 16 p.m.

Thursdays from 14 p.m. to 17 p.m.

These extended opening hours are directed towards students of the University of Siegen in order to offer additional times to work on their projects. Individuals not affiliated with the university are welcome to come to the Open Lab on Wednesdays as usual.

The same recommendations apply here as for the Open Lab:

  • no more than 20 guests in the lab
  • 3G recommended (genesen, geimpft, getestet = recovered, vaccinated, tested)
  • the mask is kindly requested to be worn at all times
    (Exception: drinking and eating in certain areas).

Reopening of the Fab Lab

Finally, we are back with good news! The Fab Lab will re-open at the beginning of the summer semester. We are thus happy to announce the date for the next Open Lab:Wednesday, April 06.

However, given the still very high number of corona cases, we have a few recommendations for visitors to the Lab:

Within the Lab we recommend to maintain the3G rule(genesen, geimpft, getestet = recovered, vaccinated, tested). Furthermore, it is recommended to wear a mask at all times. Of course, the mask may be removed for drinking, but we would kindly ask you to put it back on immediately afterwards. For this reason, open drinks (e.g. coffee/tea cups) are currently viewed with caution, as experience has shown that these lead to “Kaffeeklatsch” 😉
Instead of eating right at your workplace, we would like to ask you to consume your foodat the open (!) windows in the lobby at Startpunkt to ensure the safety of everyone staying here.

The number of visitors in the Fab Lab is limited to a maximum of 20 guests.

In summary:

  • maximum 20 guests in the lab
  • 3G recommended (genesen, geimpft, getestet = recovered, vaccinated, tested)
  • wearing the mask all the time is kindly requested
    (Exception: drinking and eating in certain areas).

Project: 3D Copy Shop A Wooden Codel Was Created from a Plaster Face Cast

A Contribution from Eri

  • A photo series was created from a plaster face mask.
  • A point cloud from the photo series was created with Linux/Colmap.
  • The points were cleaned up and processed with Meshlab
  • The milling paths were generated with Pycam.
  • The toolpath files were created with a tool developed in-house.


simplified so that the GCode can be run with the Fablab CNC software as well as NCcad.

Face1_Punkte
  • The workpiece: a 1 1⁄2 year old, dried piece of end-grain wood, pre-drilled for “spaxing” onto the sacrificial plate.
  • Cutter: 6 mm cylinder for “roughing” and 6 mm spherical head for “finishing”.

About The Manufacturing Process

The feed rate for milling could be increased significantly. The cutter length was not sufficiently taken into account during the creation. This is how the saying of the day came about: “One more delivery is possible”. Before any collisions occurred, it was stopped. After remodelling and x-times finishing (Proxxon), the following emerged:

This project was kindly supported by the University of Siegen. Many thanks for this, especially to Daniel for his collaboration and Helga for text drafting and layout.

Remark:
Only a very slow Linux notebook (Ubu 19.04) is available on site. (possibly faster with SSD or cloud computing ??)
Network access for updates planned.
Friday afternoons are aggravating and not so well suited for such projects with public traffic and the limited time of the staff.
Other spax screws are missing or have not been found.
The cutter selection is limited.
Unsolved : Chatter marks.

The Lab is now also open on Wednesdays and Saturdays

We can now offer you new opening hours for the Lab! Friday remains in place. We are also open on Wednesdays and Saturdays. We would also like to take this opportunity to remind you of our safety briefings twice a month and our plenary once a month. The 3D Printing Happy Hour merges into the Wednesday appointment and no longer exists in its own right.

The opening hours are valid until we move out of the Herrengarten.

New Opening Hours

  • Wednesdays: 13:00 – 17:00
  • Fridays: 14:00 – 20:00
  • Saturdays: 12:00 – 18:00

At these times, work can be done freely in the Fab Lab. All interested parties are welcome to attend. We are looking forward to your visit! If you want to work in the Fab Lab, you must have taken part in an appropriate safety course beforehand.

Important: We may have to cancel opening hours from time to time due to other events or teaching at the Lab. But then we’ll announce it beforehand! So before you go to the Lab, check here on this page to see if it’s really open.

Safety Instructions

Safety instructions are held at 4 p.m. every first and third Thursday of the month. Registration is not necessary. Read more here.

Plenary

On the last Thursday of the month we have our plenary for everyone at 5pm. More Information here.
Just come by.

Happy Making,
your Fab-Lab-Team
