3D Printing

 

  • Meet your future.

  • This changes everything.

  • Additive Manufacturing

  • Bioprinting

  • Materials Research

  • Education

  • Unleash your imagination.

From creating product prototypes, to manufacturing custom parts and products, from generating architectural models, to creating ceramics and sculpture, from producing fashion apparel and jewelry, to printing artificial limbs and generating replacement organs from stem cells, 3D printing is impacting every industry. Now 3D printers are entering the consumer market as fun and inspiring gadgets that produce fun and functional objects to inspire future inventors, innovators and engineers. This website provides the fundamentals of 3D printing from home applications to artictic creations, from hobbbiest to industrial applications, this page covers it all through the use of video examples.

The ABC's of XYZ's

3D Printing Basics

Consider these facts as you watch the two videos:

  • These are the common consumer-grade printers that most people have heard something about
  • Notice how the X, Y and Z printing axes control the shape of the object
  • A solid cord of plastic feedstock is fed into the printer
  • The plastic is sprayed in layers as tiny particles (3D dots) each ~ 50 - 100 µm (510 to 250 DPI) in diameter
  • These are time lapse videos! Real-time print jobs can take from a couple hours to days
  • Hollow core supportive structures are used rather than using a solid core in order to save material costs
  • These types of printers can’t print stalactites without some sort of supportive structure
  • Primary purchasing considerations include build space, build resolution, supported materials, speed, maintenance and reliability.

THIS CHANGES EVERYTHING!

 

 

Stereo Lithography (STL) Files

Acquiring Objects to Print

Consider this, as you watch these videos...

STL is the file format for objects to be printed. This section lists the most common ways to acquire STL files containing objects to be printed.

Although the learning curve can be steep, 3D modeling software allows 3D printer users to develop their own original designs, which is much more creative and interesting than simply printing items from a catalog.

Plastic Doodads

Consumer printers typically include a catalogue of doodads on DVD or Web that can be downloaded and printed.

Handheld Scanners

Ideal for mobile scanning and scanning large objects.

Fixed Scanners

Ideal for small to medium-sized objects.

3D Modeling and CAD Software

Software such as Blender, Sketchup, Rhino, Maya and AutoCAD allow you to create and edit 3D designs.

Materials

3D Printer Feedstock

Thermoplastic

  • PLA (PolyLactic Acid): bio-plastic, biodegradable, no smell, rigid, more sturdy - good for flat objects)
  • ABS (Acrylonitrile Butadiene Styrene): thermoplastic, softer more flexible - good for support structures)
  •  

  • Rubber
  • Clay
  • Ceramic Powder
  • Concrete
  • Metal Alloys
  • Titanium Alloys
  • Metal Powders

 

  • Paper
  • Wood
  • Food Ingredients
  • Stem Cells

Any material (powder, liquid, solid) that can be processed into a shaped solid.

 

3D Printing Processes

A Variety of Processes for Additive Manufacturing

Extrusion Deposition

Fused deposition modeling (FDM)

Model is produced by extruding small beads of material which harden quickly to form layers.

The method used by most consumer-grade printers and some industrial printers as well.

Makerbot Replicator2

Some prosumer models can support multiple feedstock to provide multi-color and/or multi-material objects

Polyjet

Industrial printers like this Polyjet ($250,000) create multi-color, hi-def models with moving parts.

The printing material is cured with UV light, the platform lowers 1/1000th of an inch, it utilizes two materials: a build agent and a support agent, multiple materials can be fused together, and moving parts made possible through the use of the support agent.

 

Granular Materials Binding

Model is produced through selective fusing of materials in a granular bed.

 

Lamination

Model is produced by bonding layers of a material - typically paper.

 

Photopolymerization

Stereolithography (SLA)

Produces a solid part from a liquid polymer using UV light

3D Printing Services

Because industrial printers are so expensive, businesses like Shapeways have emerged to offer 3D printing services to individuals and organizations that need hi-resolution models printed, but can't justify a big investment in a 3D printer.

3D Printing @ FSU

Blazing a Path for 3D Printing Applications in Higher Education

Academic units across FSU campus are embracing 3D printing as a resource for higher education.

While 3D printers are popping up in departments across campus, the FSU administration is supporting the propagation of 3D printing in research and education through campus-wide initiatives.

  • FSU's Stacking Layers Symposium assembles the brightest minds in 3D printing research from across the country, vendors in the 3D printing industry, and FSU students, faculty and staff to share information about best practices and new technologies.
  • iMaker FSU (opening Fall 2014) in FSU's iSchool provides an open lab where any student can learn about and work with 3D printers and scanners.
  • FSU's Program in Interdisciplinary Computing is developing information resources and courses on 3D printing for FSU's students, faculty and staff.
  • A 3D printing enthusiasts group is being organized to help foster interdisciplinary research and applications and disseminate information about this promising young technology.
