A PowerPoint 3D Printer: Missouri Teacher is Building a Unique $20 3D Printer with His Students - 3DPrint.com
When it comes to 3D printing within the classroom environment, there are some teachers who welcome it with open arms, while there are others who are deathly afraid of the technology. Some teachers have taken it upon themselves to learn how to use various 3D printers, while others have come up with some very unique lesson plans built around these new machines. However, one high school teacher in Union, Missouri is taking 3D printing to an entirely new level.
Dustin Klenke is a physics, robotics, and biology teacher at Union High School, and as part of an NSTA (National Science Teachers Association) conference that he recently attended, he learned a great deal about building his very own microstereolithographic (micro SLA) 3D printer. The presentation, which was given by a man named Joe Muskin, is part of a project run through the University of Illinois at Urbana-Champaign. It showed those in attendance the ins and outs of how to build their very own 3D printer, a printer that is based on the same concepts we see in today’s desktop DLP-based SLA printers, but which operates in its own unique way.
“The process uses an SLA gel, but instead of a laser to initiate polymerization, an ordinary data projector focused through a $3 magnifying glass displays a 2D image of each layer,” Klenke tells 3DPrint.com. “The images can be created with simple shapes in PowerPoint or slides. This solidifies an entire layer at once which eliminates the need for any moving components in the x and y-direction.”
The process is actually based on a research project that was headed up by Professor Nicholas Fang and developed at the University of Illinois. It is called microstereolithography, and it uses a simple projector to create objects with layers as small as just 400nm. Klenke tells us that $20 is enough to purchase all of the needed supplies at a hardware store. This of course doesn’t include the cost of the projector, but then again, projectors are quite common within just about every school.
“The only mechanical piece is the elevator which precisely lowers the build platform after each layer has solidified,” explains Klenke.
The way the process works is very similar to how other desktop DLP SLA 3D printers operate. A beaker is filled with a liquid polymer, while PowerPoint or a slide show is loaded up on a connected PC. To begin printing, the first PowerPoint slide is displayed through the projector which is focused on the beaker of liquid. Each image slide is exposed for about 5-10 seconds, and after each image slide comes a blank “all black” slide. When this “all black” slide is loaded, the stage on which the beaker sits is lowered, allowing the liquid polymer to flow over the existing structure. Then the next image slide is exposed, and this entire process is repeated until a full 3-dimensional object is complete.
Virtually anyone with a projector can recreate this 3D printer using the following materials:
- Drawer slide
- ¼ x 20 threaded rod
- ¼ x 20 t-nut
- 2” L-bracket (2)
- 3” straight bracket
- Carpenters Square
- 1” x 6” wood
- 2” x 4” wood
- Tape measure
- Wood screws
- Tin snips
- Aluminum sheet metal
- 8 x 32 threaded rod
- 8 x 32 nuts
- Drill (with 9/16 bit)
- Dremel tool
- WD-40 (Lubricant)
The elevator design, which Klenke’s class is in the process of building, is constructed mostly of wood, and as you can see in the images provided, the objects that this printer can create are very detailed and of the utmost quality. Klenke is one more example of a teacher who understands the importance of bringing 3D printing into the classroom. He, unlike most, is taking things a step further by allowing his students to actually build their class’ 3D printer.
What do you think about this process, and what Klenke is doing with his students? Should more teachers be following in his footsteps? Discuss in the PowerPoint MicroSLA 3D Printer forum thread on 3DPB.com.

Title: 3D Printing Future And Benefits
3D Printing Future And Benefits
- Current and future applications of 3D Printing
- In recent years, scientists and engineers have
already been able to use 3D printing technology
to create body parts and parts of organs. The
first entire organ created through 3D Printing is
expected to be done in the coming years. The
process of creating the organ or body part is
exactly the same as if you were to create a
plastic or metal part, however, instead the raw
material used are biological cells created in a
lab. By creating the cells specifically for a
particular patient, one can be certain that the
patients body will not reject the organ.
- Another application of 3D printing in the
biomedical field is that of creating limbs and
other body parts out of metal or other materials
to replace lost or damaged limbs. Prosthetic
limbs are required in many parts of the world due
to injuries sustained during war or by disease.
Currently prosthetic limbs are very expensive and
generally are not customized for the patients
needs. 3D printing is being used to design and
produce custom prosthetic limbs to meet the
patients exact requirements. By scanning the
patients body and existing bone structure,
designers and engineers are able to re-create the
lost part of that limb.
Aerospace and Automobile Manufacturing
- High technology companies such as aerospace and
automobile manufacturers have been using 3D
printing as a prototyping tool for some time now.
However, in recently years, with further
advancement in 3D printing technology, they have
been able to create functional parts that can be
used for testing. This process of design and 3D
printing has allowed these companies to advance
their designs faster than ever before due to the
large decrease in the design cycle. From what
used to take months between design and the
physical prototype, now within hours the design
team can have a prototype in their hands for
checks and testing.
- The future of 3D printing in these industries
lies with creating working parts directly from a
3D printer for use in the final product, not just
for testing purposes. This process is already
underway for future cars and aircraft. The way in
which 3D printing works (creating a part layer by
layer) allows the designer to create the part
exactly the way is needs to be to accomplish the
task at hand.Extremely complex geometry can be
easily created using a 3D printer, allowing for
parts to be lighter, yet stronger than their
Construction and Architecture
- Architects and city planners have been using 3D
printers to create a model of the layout or shape
of a building for many years.Now they are looking
for ways of employing the 3D printing concept to
create entire buildings. There are already
prototype printer systems that use concrete and
other more specialized materials to create a
structure similar to a small house.
- The goal is the replace many cranes and even
construction workers with these printing systems.
They would work by using the 3D design model
created on CAD software, to create a layer by
layer pattern on the building just as a normal 3D
printer works today. Most of the innovation in
this area will have to come from the creation of
the appropriate materials.
- The creation of a new product has been always one
that involves many iterations of the same
design.3D Printing revolutionized the industry by
allows designers to create and the next day see
and touch their design. No longer did it take
several meetings for everyone to agree on one
design to create, and then wait months for the
actual part to arrive. Nowadays a version of each
idea is created and the next day, all are
reviewed together, thus giving the ability to
compare and contrast each ones features.Plastic
parts, for example, require molds and tooling to
be created, these custom parts are expensive to
create, therefore one must be certain the part
designed meets the requirements. With 3D printing
you can create a part that will look and feel
exactly like the finished product. Some parts can
also be tested just as the real injection molded
3D Printing Benefits Value
- 3D printing, whether at an industrial, local or
personal level,brings a host of bene fits that
traditional methods of manufacture (or
prototyping) simply cannot.
- 3D printing processes allow for mass
customization the ability to personalize
products according to individual needs and
requirements. Even within the same build chamber,
the nature of 3D printing means that numerous
products can be manufactured at the same
time,according to the end-users requirements at
no additional process cost.
- The advent of 3D printing has seen a
proliferation of products (designed in digital
environments), which involve levels of
complexity that simply could not be produced
physically in any other way. While this advantage
has been taken up by designers and artists to
impressive visual effect, it hasalsomade a
significant impact on industrial applications,
whereby applications are being developed to
materialize complex components that are proving
to be both lighter and stronger than their
predecessors. Notable uses are emerging in the
aerospace sector where these issues are of
- For industrial, manufacturing, one of the most
cost-, time- and labor-intensive stages of the
product development process is the production of
the tools. For low to medium volume applications,
industrial 3D printing or additive
manufacturing can eliminate the need for tool
production and, therefore, the costs, lead times
and labour associated with it. This is an
extremely attractive proposition, that an
increasing number or manufacturers are taking
advantage of. Furthermore, because of the
complexity advantages stated above, products and
components can be designed specifically to avoid
assembly requirements with intricate geometry and
complex features further eliminating the labour
and costs associated with assembly processes.
- Sustainable / Environmentally Friendly
- 3D printing is also emerging as an energy-e
efficient technology that can provide
environmental efficiencies in terms of both the
manufacturing process itself, utilizing up to 90
of standard materials, and, therefore, creating
less waste, but also throughout an
additivelymanufactured products operating life,
by way of lighter and stronger design that
imposes a reduced carbon footprint compared with
traditionally manufactured products.!Furthermore,
3D printing is showing great promise in terms of
fulfilling a local manufacturing model, whereby
products are produced on demand in the place
where they are needed eliminating huge
inventories and unsustainable logistics for
shipping high volumes of products around the

3D Print and 3D Printer Presentation, Report
Author Salatina E. A., Salatin S. A.
Material taken from: make-3d.ru
What is a 3D printer?
The principle of operation of a 3d printer is based on the principle of gradual (layered) creation of a solid model, which, as it were, is “grown” from a certain material. The advantages of 3D printing over the usual, manual methods of building models are high speed, simplicity and relatively low cost.
There are various 3D printing technologies. The difference between them lies in the way the product layers are applied.
The most common are SLS (selective laser plexus), HPM (molten material overlay) and SLA (stereolithiography).
The most widely used technology due to the high speed of building objects is stereolithography or SLA.
The technology works like this: a laser beam is directed at a photopolymer, after which the material hardens.
The photopolymer is a translucent material that deforms when exposed to atmospheric moisture.
Once cured, it can be easily bonded, machined and painted. The working table (elevator) is in a container with a photopolymer. After the laser beam passes through the polymer and the layer hardens, the working surface of the table moves down.
Laser beam sintering of powder reagents - aka SLS - is the only 3D printing technology that is used in the manufacture of molds for both metal and plastic casting.
Plastic models have excellent mechanical properties, which make them suitable for making full-featured items. SLS technology uses materials that are similar in properties to the brands of the final product: ceramics, powdered plastic, metal.
The 3D printer device looks like this: powder substances are applied to the surface of the elevator and sintered under the action of a laser beam into a solid layer that corresponds to the parameters of the model and determines its shape.
DLP technology is new to the 3D printing market. Stereolithographic printers are positioned today as the main alternative to FDM equipment. This type of printer uses digital light processing technology. Many people wonder what the 3d printer of this sample prints with?
Instead of a plastic filament and a heating head, photopolymer resins and a DLP projector are used to create three-dimensional figures.
Despite the intricate name, the device is almost indistinguishable from other desktop printers. Its developers, represented by
QSQM Technology Corporation, have already launched the first samples of high-tech equipment into a series. It looks like this:
HPM technology (FDM) HPM
Allows you to create not only models, but also final parts from standard, structural and high-performance thermoplastics. It is the only technology that uses production grade thermoplastics to provide unparalleled mechanical, thermal and chemical strength to parts.
HPM Printing stands out for its cleanliness, ease of use and suitability for office use. Thermoplastic parts are resistant to high temperatures, mechanical stress, various chemicals, wet or dry environments.
Soluble auxiliary materials allow the creation of complex multi-level shapes, cavities and holes that would be problematic to obtain with conventional methods. HPM 3D printers create parts layer by layer by heating the material to a semi-liquid state and extruding it according to computer-generated paths.
When the 3D printer has finished creating the part, it remains to separate the auxiliary material mechanically, or dissolve it with detergent, after which the product is ready for use.
Hand-printing pens are also popular these days. Moreover, it would be correct to call them not printing devices, but pens for drawing three-dimensional objects.
Pens are made in the same way as fusing printers. The plastic thread is fed into the pen, where it melts to the desired consistency and is immediately squeezed out through a miniature nozzle.
Applications of 3D printing
3D printing has opened up great opportunities for experimentation in areas such as architecture, construction, medicine, education, fashion design, small-scale production, jewelry, and even in the food industry. In architecture, for example, 3D printing allows you to create three-dimensional models of buildings, or even entire microdistricts with all the infrastructure - squares, parks, roads and street lighting.
Thanks to the cheap gypsum composite used, the cost of finished models is low. And more than 390 thousand CMYK shades make it possible to embody any, even the most daring, imagination of an architect in color.
3D printer: application in the field of construction
In construction, there is every reason to believe that in the near future the process of erecting buildings will be much faster and easier.
