FabLab

As an asset of the FIT Library, FabLab is a professional digital fabrication lab that handles 3D printing and laser cutting services for students, staff and faculty of FIT. It is currently equipped with 2 Stratasys uPrint+ 3D printers and 1 Universal Laser System VLS3.60 60 watt laser machine.  Class projects will need to be discussed by FabLab management before being accepted. All submitted work must be properly setup before we start any work.  Files that are not setup properly will not be corrected and will be returned to the customer for correction. If you have any questions, comments or concerns, please contact FabLab staff in Pomerantz D529A.

3D Printing

The 3D printer is capable of quickly creating durable and accurate 3D models out of ABS plastic. It reads STL (STereoLithography) files and builds models by extruding a bead of ABS plastic through a computer-controlled extrusion head, working layer by layer, from the bottom up (see video). It has a vertical layer resolution of .010 inches (.254mm), a minimum wall/feature thickness of .036 inches (.914 mm), and a maximum build size of 8” by 8” by 6”.

Acceptable Files

  • Only STL files will be accepted for 3D printing.
  • Most 3D CAD platforms (e.g. AutoCAD, SolidWorks, Rhino, etc) can natively export 3D files as STLs.
  • Maya can export STLs with the aid of a downloadable MEL script.
  • zBrush can export STLs with the aid of a downloadable plug-in.
  • Blender (open-source/free) can be used to convert OBJs and a few other common file formats to STLs.

Checking Files for Errors

All 3D file formats are prone to errors in geometry. The most common errors are inverted faces due to reversed normals, and holes in the mesh due to bad/open edges. Files with these errors will not print correctly and must be fixed by the client before a job can be submitted to our 3D printer.

Netfabb Basic is a free STL viewer which can open your 3D files and diagnose inverted normals/faces and bad edges.  A Netfabb Basic video tutorial is available here and it's also installed on the PCs in the Self-Service area of PrintFX. It can also be downloaded at http://www.netfabb.com/downloadcenter.php?basic=1

Cost

Use of the 3D Printer is $7 per cubic inch. You are responsible for paying for all build and support material. When dropping off your job, you must indicate on the order form whether you would like to be called with a cost estimate prior to printing your model. All jobs must be paid for with your FIT ID card before the job is released.

Procedures & Policies

  • All work must be setup according to our file prep guidelines. We will not correct any files that are setup incorrectly. They will be returned for correction.
  • Turnaround time currently is three days. All jobs must be paid for with your FIT ID card before the job is released.

Laser Cutting

The FIT Library FabLab is equipped with a Universal Systems VLS3.60 Laser Cutter. The VLS3.60 has a material processing platform of 24” x 12” x 9” and a 60 watt laser.

Accepted file types

Illustrator files: Vector Cutting, Vector Engraving, Raster Engraving. Photoshop files: Raster Engraving

JPEGs: Raster Engraving

FabLab staff will not resize, adjust, or manipulate your files. Files must adhere to the color, format and size requirements of the laser cutter program before being submitted. If any changes are required to successfully complete the job, the FabLab will not proceed until the client fixes the errors and resubmits the corrected file. The FabLab is not responsible for cutting or engraving errors if they are a result of an improperly prepared file.

Accepted materials: Only the following materials will be accepted for use with the laser cutter:

Bristol Board, Butter Board, Cardboard, Chipboard, Museum Board, Poster Board, Fine Art Paper, Cardstock, Illustration Board, Construction Paper, Matte Board, Marker Board,  Wood Veneer, Basswood, Plywood, Balsa Wood, Birch Wood, Cork, Leather,  Rubber, Glass (Etch only), Marble (Etch only), Acrylic Sheets (Paper-backed), Natural Fabrics, Hard Woods.  

Please see our separate acceptable materials list for local suppliers and online vendors. We reserve the right to refuse material if we deem it to be unsafe or inappropriate.

Testing material

For non-standard or specialty materials, we recommend supplying a separate piece of material (recommended at least 2”x4”) for the FabLab staff to test to determine the correct laser settings. This testing is covered by the $5.00 setup fee per material submitted. We will do our best to determine suitable settings, but depending on the results of the testing, the FabLab may not be able to perform your job exactly as submitted. We will not replace damaged testing material.

The client is allowed to keep any scrap material from their job. If the client does not supply a separate piece of testing material, the FabLab may use areas of the client’s scrap material to perform testing.

Procedures & Policies

Please come to the PrintFX service desk in Pomerantz D529A to complete a Laser Cutting Order Form. All jobs must be paid for with your FIT ID card before the job is released.

Turnaround time currently is three days. All jobs must be paid for with your FIT ID card before the job is released. Standard $5.00 minimum fee. After this initial setup fee (per material), the price for use of the laser (for Vector Cutting, Vector Engraving, and Raster Engraving) is $0.50 per minute.

Vector Cutting & Engraving

The laser cutter can cut or engrave along vector paths. The laser cutter program will “read” your Illustrator file, and depending on the Stroke Weight and Color of a vector, the laser will cut through or engrave (i.e. scorch/mark) the surface of your material. In order for your Illustrator file to be read by the laser cutter program, your files must be in RGB Color Mode.

Vector Cutting

Lines that you would like to be cut through your material should be Vector Paths in your Illustrator files, with a Stroke Weight of .001 pt and colored RGB Red (255-0-0, or #FF0000). Materials to be cut must be 1/8th inch or less. Depending on the density of the material, certain objects may not be able to be cut at all. Please see our approved materials list.  

Vector Engraving

Lines that you would like to engraved on the surface of your material should be Vector Paths in your Illustrator files, with a Stroke Weight of .001 pt and colored RGB Blue (0-0-255, or #0000FF). Depending on the density and surface texture of the material, certain objects may not be able to be engraved at all. Please see our approved materials list.

Raster Engraving

When Raster Engraving, the laser cutter travels in horizontal lines, moving down the image (like an inkjet printer), engraving (i.e scorching/marking) the surface of the material. Any type of image can be Raster Engraved. Images to be Raster Engraved should be grayscale or B&W. Black colors in the image will be engraved the deepest and colored darkest, and lighter shades of grey will be progressively engraved shallower and colored lighter.

Cutting, Engraving & Raster Engraving

The laser cutter can Vector Cut, Vector Engrave, and Raster Engrave all from one image. Import grayscale or B&W images (JPEG or PSD) into an Illustrator file, and follow the guidelines for Stroke Width and Stroke Color for vectors described here. The laser cutter program will automatically distinguish between vector paths meant to be cut, vector paths meant to be engraved, and grayscale or B&W artwork will be Raster Engraved.

Helpful Tips

Vector Cutting & Engraving: Depending on the physical properties of the material, the line being cut or engraved will have a variable “thickness.” This is determined by how the material reacts to being burned or scorched by the laser. Vector artwork should be designed with this in mind, as vector paths that are very close together in an Illustrator file may actually overlap or touch once cut (or engraved) onto the material.

Raster Engraving: Higher contrast images are desirable. Depending on the characteristics of the material being engraved, the range of dark to light tones (i.e. the depth being engraved) may be very limited --- in some cases only a two-tone, black & white color range is possible.
