College Kids Design Desktop 3D Printer to Be Crowdfunded and Sold For Under $500

Deltaprintr Desktop 3D Printer Coming Soon to Kickstarter and Maker Faire

“We designed the Deltaprintr to be simple without sacrificing anything.” — Deltaprintr team

Deltaprintr is a new desktop 3D printer concept that is targeting a retail price of under $500. Created by a team of college students, the savings come from a desire to simplify, not limit, capabilities.

“The project’s inception occurred when I had built a RepRap for our University due to limited availability of funds at the time,” said Shai Schechter, the tech guru behind Deltaprintr, in an interview with On 3D Printing. “After noticing 3D printing’s potential in the classroom and rising demand from fellow college friends, we decided to make our own 3D printer that not only those who can afford to spend more than $1,000 on their printer can buy, but college students as well.”

The team began working on their desktop 3D printer in May and are in the process of finalizing production costs. Schechter said proudly, “we are currently on track to sell at retail under $500.”

The Deltaprintr Team

The founding Deltaprintr team is composed of electrical and mechanical engineers, finance, and a graphic designer. But there is also a great response from the community, Schechter explained, “with a lot of positive feedback and a lot of anxious people waiting for us to launch.”

Desktop 3D printer leader MakerBot, sellers of the $2,200 Replicator 2 desktop 3D printer, was recently acquired by Stratasys for $403 million. Perhaps this team can strike gold with their more affordable design.

The company has launched teaser videos on YouTube and high quality images of its 3D printer. Below is an image gallery and their teaser video.

See Deltaprintr at Maker Faire and on Kickstarter

Deltaprintr will be exhibiting at the World Maker Faire this September 21-22 in NY.

Schechter tells us they are also planning on launching a Kickstarter campaign sometime in October or November. Stay tuned here for more news on Deltaprintr.

Study Shows 3D Printing Emits Ultrafine Particles; What This Actually Means

3D Printer Ultrafine Particle Emissions

Should You Use Your 3D Printer Indoors? Study Asks, We Explain

A recent study published in the journal Atmospheric Environment shows evidence that desktop 3D printers emit ultrafine particles (UFP) to a degree that should cause concern, if you operate your 3D printer in a telephone booth.

The report focuses on emissions by FDM (fused deposition modeling) printers that use ABS or PLA material, a configuration used by MakerBot and other popular desktop 3D printer companies.

Ultrafine particles are small particles, technically on the nanoscale, that can be inhaled and cause health effects ranging from innocuous to major, including lung disease.

The report claims that observed emissions of UFPs from desktop 3D printers were significant and therefore caution should be used when operating in a unventilated area.

Estimates of emission rates of total UFPs were large, ranging from ∼2.0 × 1010 # min−1 for a 3D printer utilizing a polylactic acid (PLA) feedstock to ∼1.9 × 1011 # min−1 for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) thermoplastic feedstock. Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments.

At first glance, this sounds like a big problem for 3D printing, an industry in rapid growth and adoption. But the reality is that the level of emission observed is similar to that of laser printers, candles, and cooking on a stove at home – all activities consumers are not going to give up any time soon.

The same 3D printer utilizing a higher temperature ABS feedstock had an emission rate estimate (1.8–2.0 × 1011 # min−1) similar to that reported during grilling food on gas or electric stoves at low power (1.2–2.9 × 1011 # min−1), but approximately an order of magnitude lower than gas or electric stoves operating at high power (1.2–3.4 × 1012 # min−1). Regardless, the desktop 3D printers measured herein can all be classified as “high emitters” with UFP emission rates greater than 1010 particles per min, according to criteria set forth in He et al. (2007).

In summary, don’t use your 3D printer in a dark corner of your basement without opening the window.

Student Creates LEGObot 3D Printer Made Entirely of LEGOs

LEGObot 3D Printer

LEGObot 3D Printer

Engineering student Matt Kreuger loves LEGOs and 3D printing, so why not combine those passions? Kreuger is the creator of the LEGObot, a 3D printer built almost entirely out of LEGO blocks.

Unlike other desktop 3D printers, the LEGObot is limited to hot glue which makes it more of a novelty than utility, but not bad for a first version!

Kreuger posted his design on Instructables along with this story and video.

Ever since I saw the first makerbot, I have been obsessed with 3D printing, but I am an engineering student so I don’t have an extra $800-$2500, and have been doing my best to create one out of what I have on hand. I tried arduino with easy drivers, and parallel port, but neither one gave results, I always needed a tool or part that I couldn’t get.  So I pulled out my old box of legos and started building.

This is a project I have been working on for the past year, it prints in hot glue and made almost completely out of legos.  Based roughly on the first version of the makerbot, while it does print, I would call this more of a prototype than a finished project.  I am using 4 power supplies (3v extruder, 7.2v for nxt, 12v fan, and 115 for hot glue gun) and having to manually turn the extruder on and off, (although i am working on that one) . Unfortunately,  due to my lack of computer programming skills, every move has to be manually programmed from the NXT programming software, I have yet to find a g-code interpreter for the NXT.

Hopefully in the next version I will be able to shorten the height of the platform, reduce wobble, and use g-code files.
but in the mean time, I have included a Lego Digital Designer file with the full printer in it, just about all the technic parts are exactly the same as in my printer, but for the structure I used different parts to speed the digital building process, the structure and dimensions are still the same. under each X and Y axis there are 2 suspended blocks that I placed coins in to balance the weight of the motor on each side, for the extruder motor I used a lens adjustment motor out of an old VHS camera because it was low speed/high torque. In the .ldd file, the green box on the right side of the extruder gears is the case I made for it, it works perfectly.

While hot-glue works, its very rubbery and doesn’t have many practical uses, if only one or 2 layers are printed then it will stick to glass to make window stickers, but its not sturdy or rigid, I will be experimenting with printing using wax and heat-melting resins in the future. I am currently limited to what I can make with what I have at hand, some more printed parts could really improve accuracy on this.  I initially did not have enough gear racks so I asked someone who had a 3D printer at work if he could help me out, I was able to get around 30 of them printed, and while they work, they do not connect perfectly to the legos, which is what causes most of the wobble in the platform.
