FabLab

As an asset of the FIT Library, FabLab is a professional digital fabrication lab that handles 3D printing, laser cutting and vinyl cutting services for students, staff and faculty of FIT. It is currently equipped with two Stratasys uPrint Plus 3D printers, one FormLabs Form 2, one Universal Laser System ILS 12.75 laser cutter (new larger model) and one Roland GS-24 vinyl cutter.  The self service area has two MakerBot Replicator + 3D printers, one Ultimaker 2+ Extended 3D printer, one NextEngine Ultra HD 3D scanner, one Touch 3D Stylus and two 22HD Wacom Cintiqs. 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 which may change the turnaround time. If you have any questions, comments or concerns, please contact FabLab staff in Pomerantz D529A. 


Full-Service Vinyl Cutter 

The Roland GS-24 vinyl cutter is capable of making quick and accurate cuts onto vinyl using vector based design files. Applications include signage, packaging, book, laptops, walls and basically any other surface where you would like to promote your identity. The FabLab currently offers 8 colors of durable self-adhesive vinyl for making single colored die cut stickers as well as two types of printable self-adhesive vinyl capable of making custom ‘print-and-cut’ stickers. The cutter has a maximum cutting width of 22.5” (3/4” margins). 

Acceptable Files: Only vector based Adobe Illustrator files will be accepted for vinyl cutting.

Procedures & Policies

  • Convert all fonts to outlines
  • A 'print & cut' job must be dropped off at the same time
  • Very small & overly complex artwork may not cut properly. Letters must have a minimum height of 1/2". Cutout shapes should be a minimum 1/16"
  • Application tape (transfer tape) which aids in aligning artwork when pressing into place is optional
  • Cutting vectors and artwork should be on separate layers with a 3/4" uncuttable margin on both sides
  • Lines that you would like to be cut on the vinyl should be vector paths in your Illustrator file. The vinyl cutter uses these vectors as tool paths to trace along with a blade

Pricing

  • Single color vinyl cutting: $.50/linear inch
  • High quality ink jet printed clear or white vinyl cutting: $2/linear inch
  • Application tape: additional $.25/linear inch

Full-Service 3D Printers

The Stratasys uPrint Plus prints durable and accurate 3D models out of ABS plastic. It builds your model by extruding melted plastic layer by later in a process known as Fused-Deposition Modeling (FDM)printing (see video) and utilizes dissolvable support material that is washed away automatically in a specialized bath.

Build size: 8" x 8" x 6"
Layer resolution: 0.33mm to 0.0254mm

 

The FormLabs Form2 prints extremely high detail 3D models in a variety of specialized plastic resins. It utilizes stereolithography, fusing photo-sensitive polymers into solid objects with focused points of light. Stereolithography allows for much higher detail than FDM printing, as well as printing in flexible and castable resins, but the Form2 has a smaller print bed and a more involved support-removal process.
 
Build size: 5.7" × 5.7" × 6.9"
Layer resolution: 0.100mm to 0.025mm

 

Self-Service 3D Lab

For students interested in gaining hands-on experience with new 3D technology, PrintFX and FabLab's self-service 3D Lab (D529A) is now equipped with two MakerBot Replicator + 3D printers, one Ultimaker 2+ Extended 3D printer, one NextEngine 3Dscanner, one Touch 3D Stylus and two 22HD Wacom Cintiqs. The lab closes 30 minutes prior to PrintFX closing and the equipment is available on a first-come, first-serve basis.

3D Printing

Fablab self service 3D printers

The MakerBot Replicator +  is a hobbyist-level 3D printer that prints inexpensive models out of PLA filament (a corn based bio-plastic) using Fused-Deposition Modeling (FDM) technology. With proper preparation, the MakerBot can produce good results on basic models, but they are limited by their low detail level and support material that can be time-consuming to remove. In addition to using our full-service 3D printers, the MakerBots give students the opportunity to learn the software associated with preparing, customizing and sending 3D prints to the printer. A dedicated PC workstation is provided for utilizing this software.

Build size: 11.6" X 7.6" X 6.5"
Layer resolution: 100 microns [0.0039"]

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

Fixing Files

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

3D Software

PC: NetFabb Basic, Rhinoceros 4.0, 5.0, Penguin 2.0 for AutoCad, MakerBot, Solidworks Electrical 2D and Composer 2016, Solidworks 2016, Autodesk 3ds max 2018, Cura (Ultimaker), Revit 2018.

MAC: CURA (Ultimaker), MakerBot.

Support Material

All 3d printers generate support material differently, and all support material types have different post-processing and finishing requirements. The uPrint's support material is dissolvable and washes away in a cleansing bath. The Form2 and MakerBot printers do not have dissolvable support material and their support structures must be clipped and/or sanded away manually.

Measurements in NetFabb Basic

In the bottom right panel of the Netfabb window, you will see basic dimension information about your part, including size and volume, which can be used to estimate your cost (not including support material). 
 
For a more detailed guide on how to use Netfabb to measure and resize your models, please refer to our video guide which can be found at    http://youtu.be/7pg_CESwWj8

User guides, documentation and tutorial videos are provided, but the scanner is intended for self-service use only. Hands-on instruction will not be available at this time.

Laser Cutting

The FIT Library FabLab is equipped with a Universal Systems ILS 12.75 Laser Cutter (new larger model). The ILS 12.75 has a material processing platform of 48” x 24” x 12” and a 75 watt laser.

Accepted file types

Illustrator files: Vector Cutting, Vector Engraving, Raster Engraving. Photoshop: JPEG files for 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 ink jet 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 gray 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.
