CNC Routers and Laser Cutters can be booked 48 hours in advance. During busy times i the Bartlett schedule these can be very busy with queues
outside the office to book from 8am, so get there early! CAD/CAM workshop times: 9.30am 8211; 4.30pm (Closed for lunch 1-2pm)
Cost of all machines for Slade students is £15 per hour, with the exception of the Slade CNC router which will be charged at cost (check in workshop for details).
DMC London, is the Bartlett’s new, state-of-the-art digital manufacturing (DM) centre. Bringing together two key technologies, and associated software solutions, the centre services all the DM requirements of the school, the wider needs of the UCL community, as well as, providing a highly valuable service to SMEs and micro-companies from within Greater London.
To access any of the technologies detailed below, it is first necessary to generate a 3D CAD file of your design and export this into .stl format. The majority of 3D CAD packages have this export facility.
The way you process your three dimensional data will depend on the 3D program you are using to model in. Different programs utilise different approaches to modelling, however, the following points need to be considered independently of your software type:
Ultimately the data you supply needs to be in .STL format. The three dimensional geometry created in your 3D program can be converted to this file format typically under the File8211;Export menu of most programs.
All geometry to be 3D printed must be in three-dimensions. Any two-dimensional geometry will not be processed or built by the 3D printer.
All three-dimensional geometry must consist of closed volumes. Further, all closed volumes must have a minimum of 1mm thickness. Single surfaces cannot be built.
Generally it is best to unify any parts that are attached in to one file, and surface normals should be correctly orientated.
Some issues can be fixed in our software, but some will need to be corrected first in the native software. With typical deadlines in mind, it is good practice to bring the model down to us as early as is possible to help identify any problematic data.
Once you have checked that your file consists of only three dimensional closed volumes you are ready to export your file.
Translate your model to the HOME axis of 0,0,0
Scale your file to final print output size
Change the units in your application to millimeters
Exporting an STL file usually involves the ‘Export’ or ‘Save As’ function. STL is the most common file format for use in 3D printing. Your three-dimensional design will be converted to a three-dimensional triangulated polygon mesh, made up entirely of triangles. STL stands for Standard Triangulation Language.
If your application does not export to STL the next preferred file formats are .3ds and .dwg. This format can be brought into almost any 3D CAD application and exported to STL from there.
Double check your .STL file to ensure it looks right and is to the correct size and scale
