3D printing has been a focal point in library makerspaces for several years; however, it seems that interest in the technology has decelerated. The technology may have slowed down, but there is still a lot going on in this space, which can be overwhelming to keep up with it all. In this webinar: - Learn what 3D printing is, how it works, and gain insight on how to implement/maintain, and to perhaps build your own 3D printer. - Get a snapshot of some of the best 3D printers and products on the market, including an overview on resin and carbon printers. - Discover a variety of 3D design applications to help with getting ideas to working prototypes. - Study trends in digital scanning and other emerging 3D design/printing technologies. - Interview an expert 3D designer/printer in the industry to get even more insight into this exciting technology.

4. What is 3D printing?
3D printing, also known as additive manufacturing, is a
process of making, layer by layer, three dimensional
objects from a digital file.
Most desktop printers use Fused Deposition Modeling
(FDM) technology (i.e., material extrusion)

6. 3D Printing File Types
.STL – STereoLithography or Standard Tessellation Language
.OBJ – Object files define the geometry for objects. Includes textures.
.3MF - 3D Manufacturing Format full-fidelity 3D models.
.PLY - Polygon File Format stores data from 3D scanners.
.X3D – used for color printing. Also added shaders, geo-location etc.
.VRML – used for color printing. Includes 3D geometry etc.

7. 3D Printing Process
1. Design an object via computer aided design (CAD) or modeling software
(e.g., Blender, Inventor, TinkerCad etc.). Not design-oriented? Try
Shapeways, Sculpteo or Thingiverse.
2. The software will export the object as an .STL file, which will then be
built (printed) layer-by-layer (i.e., Additive Manufacturing).
3. Load the .STL file into the printer. (e.g., via Repetier).
4. Slice (i.e., create layers for the object). Note: Repetier integrates Slic3r
into the software.
5. 3D printing materials vary. We use PLA (Polylactic Acid) filament. Visit
http://reprap.org/wiki/PLA for more information.

8. G-code is a language where people tell
computerized machine tools how to make something. G-code
can also be used for CNC machines, knitting, tattoos etc.
Visit http://3dprintingforbeginners.com/software-tools for a large list of other 3D modeling, Slicer, 3D Printer Hosts etc.

9. What to Expect with 3D Printing
• It is a slow process.
• It can be frustrating at times, but also very rewarding.
• You will learn how to unclog the extruder and do other repairs.
• Have a web form for print submissions with brief explanation.
• Create procedures/policies.
• Setup a way to remotely monitor your prints (e.g., use a webcam via
RealVNC or Repetier-Server etc.)

19. Bed Leveling

20. The nozzle should be about 0.4MM above the
bed. Check your layer settings in slicer.
There should be some friction (i.e., tension from the
paper) on each corner of the bed and in the center.

21. Maintenance Tips
•Clean the heat bed with rubbing alcohol.
•Unclog and clean the nozzle often.
•Make sure the belts are tight.
•The screws should all be tightened equally.
•Clean and lube the X and Y rails.

66. Special Guest: Fri Rieder
Fri was born in Bern, Switzerland on August 3rd, 1967. In 1998, he moved to Los Angeles and
2 years later he ended up in Tulsa, Oklahoma. He was working in the printing industry with
an emphasis on mechanical engineering. Fri was educated as a printing professional and has
over 12 years of work experience.
In 2004, Fri moved to St. Petersburg, Florida. The company he worked for had a requirement
for a prototype. While he could outsource most of the parts, he started looking into 3D
printing to create the parts himself. He bought his first machine and started to modify it, as it
was not working out of the box. Fri is one of the first people in St. Petersburg with a 3D
printer. As a result, he quickly got orders for 3D printed parts. From that, he started his own
company in 2013 called FreeDimension LLC, at the same time he co-founded FreeFab3D, a
local 3D printer manufacturer.
FreeDimension has five FDM 3D printers and one SLA machine, as well as one with CNC
capabilities. His range of products widened over time to product development, sign making,
and the development of fully-functional prototypes.
Most of their customers are looking for help making a product, prototyping it, and getting it
to the market. FreeDimension is their one stop shop for that!
