 Guide to Professional 3D Printers

There are over 100 industry-grade 3D printer models currently on the market. These printers are large, commercial 3D printing machines intended for professional use. At Sculpteo we exclusively uses professional 3D printers.

We’ve put together a guide to these industrial 3D printers based on a selection of printers from each manufacturer that best represents the range of options out there — from price to materials to build size.

We hope this guide will help you determine the best 3D printer for your business needs. And don’t forget, you don’t have to buy your own printer to have access to professional quality 3D printing. Sculpteo offers an online 3D printing service using a variety of the printers listed in this guide.

Note on pricing: Because commercial 3D printers are sold through third-party, licensed resellers, there is not a standard retail price for each printer. Prices are only available via a quote from one of these resellers. We have recorded the pricing below based either on a quote from a reseller that asked to stay anonymous or from another online source (with a link).

The guide is organized by printer technology. For details explaining each process, check out The Different Technologies Behind 3D Printing.

Space: The Final (Maker) Frontier

Andrew Back

A look at three relatively low cost routes to getting your electronics project into space.

There was a time — not that very long ago — when if you wanted to get a functional piece of electronics into space it took an obscene amount of money and a few hundred tonnes of volatile rocket fuel. Suffice to say that, unless you were part of a national space programme, a global telecoms company or an evil supervillain, you were probably out of luck.

Thanks to ever smaller and lower cost technologies, coupled with a burning desire to get in on the action and a healthy dose of inventiveness, this is all changing — and at a somewhat rapid pace. This post takes a look at just a few of the options available for getting your project into space.

Spraying natural fibers to build cotton-candy surfaces

Zoe Romano

During Fab10- Fab Festival in Barcelona I met Jin Shihui who introduced me to CandyProject, a research project exploring the process of spraying natural fiber to create a non-woven textile that can be used to produce anything from building components to ornamental artifacts.

By means of air pressure we separate the fibers from a roving allowing them to self-organize and reassemble due to the surface tension caused by a fine mist of adhesive. This creates a controlled fibrous aggregation producing an emergent morphospace encompassing the initial substructure.

The robot Jin is holding in her hands in the picture above uses air pressure to separate fibers into individual strands. While the fibers are still separated they are embedded with an adhesive spray and all parameters are controlled within the robot  with an Arduino Uno:

Homebrew Arduino Pulse Monitor (Visualize Your Heartbeat)

ASCAS

Movies look cool with those EKG (electrocardiogram), the one that beeps and detects heart activities. A few months ago, we had to shoot a hospital scene for our school project. We needed an EKG instrument. To keep the movie authentic, we didn't want to fake the readings so we made the next best thing, a pulse monitor. Since my dad is a doctor he gave me some advice to design the pulse monitor.

iTorch

Media Sharing

Created By: Travis Higgins
This Instructable is for a prototype homemade projector that can be illuminated by any decent LED flashlight/floodlight.

This is my first published instructable so please leave comments and/or suggestions! Any feedback is very welcome and I will try to respond to everyone as soon as I see it!

At this stage the iTorch is a kit that I hope to be able to make available if I were to somehow get my hands on my own laser cutter. I have been spending a good amount of money using school equipment to laser cut this project, and got a quote to use the 3d printer and the price was astronomical. So needless to say a laser cutter and 3d printer would go to good use and be greatly appreciated.

Though you could probably reverse engineer one of your own. ;)

India starts countdown for Mars mission

David Szondy

India has started the clock on its most ambitious space project to date. On Sunday at 6:08 IST, the Indian Space Research Organisation (ISRO) began the countdown for its Mars Orbiter Mission (MOM). If all goes to schedule, the unmanned probe will lift off on Tuesday from the First Launch Pad at the Satish Dhawan Space Centre (SHAR), on the island of Sriharikota at 2:38 pm IST atop a Polar Satellite Launch Vehicle (PSLV-C25), marking the point where India hopes to launch itself into the space-faring big leagues.

Da KJMagnetics, eis mais umas dicas sobre Magnetismo, aqui, a Lição é sobre a Direcção das Linhas de Força num Campo Magnético, e como os Ímanes de Neodímio são magnetizados:

All About Magnetization Direction

What do we mean by a magnet’s Magnetization Direction?  Why do we care about this?  Can a magnet’s magnetization direction be changed?  What’s the difference between axially and diametrically magnetized magnets?  How can I tell them apart?  Why can’t I get a block magnet magnetized along the length or width?  What magnetization direction should be used with directional sensors?

What do we mean by a magnet’s Magnetization Direction?  Is it important?

The strong magnets found at K&J Magnetics are called sintered neodymium magnets,.  They are the most powerful type of permanent magnet available.  Sintered means the metal is pressed together at high temperatures in a very specific way to make a strong magnet.  You can learn a bit more about this process in How Neodymium Magnets are Made.

Discovery shines a light on potential cure for Alzheimer's and Parkinson's

Darren Quick

It is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.
Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease are thought to be caused by aggregates of amyloid beta protein that start to inhibit proper cellular processes in the brain. Although it is technically possible to cure the diseases by detecting and removing the amyloid protein aggregates using chemicals, these chemicals are highly toxic and harmful to the patient.

A Centrifuge built from VCR parts

kymyst

A centrifuge is a very useful piece of equipment for isolating aquatic organisms. Centrifuging a sample of water containing micro organisms will drive them to the bottom of the container, where they become more concentrated and easier to manipulate. A high speed laboratory model costing several hundreds of dollars isn't necessary for the purpose, something much simpler will do the job quite adequately. At the most basic, you can just tie a piece of cord SECURELY to the container and whirl it around your head. You can easily generate a centrifugal force of 10 G with this method ( but do it outside in an open area, where nothing will get damaged if it comes loose ! )

DIY - Portable Mini Photo Studio

faziefazie

For publish my project on instructables, I need to take lots of photos and needed a handy place to quickly take the step-by-step project shots that has a plain background and lots of light. I always work in my bedroom, that have a minimal lighting and just a have a little space. When I took photos of projects that I made, especially for electronic project that have a lot of small components – there was always a distracting background and became blur because of the lighting. So I think, it will really helpful if I have my own photo studio.

There are Mini Photo Studio tent and lighting kit that you can buy from eBay or other online shop, it is compact, portable and easy to set up, Mini Kit Photo Photography Studio . But the price are not friendly for me. So I could make that, from cheap materials and it cost me just about $1.

Sydney Harbour Bridge: CNC Laser to Router Conversion 3 ~ Taking Shape 

Continuing on the file conversion here on CNCKing.com… As I design all my models based on material thickness, these kind of thickness issues will reek havoc on the final design if I don’t catch all of them. Although I work in a 3D environment, it’s really 2D extruded to the material thickness. In this picture, you see a major problem. If I layer a piece over the bottom step that’s 4mm (squares help for sizing), I will have 2mm sticking out and intersecting the piece above it. Solution? Bring it down to 4mm and review the model closely to catch all of these.
The model will already be highly modified simply due to the span doubling but throw-in a 150% increase in size using the same material thickness and what may “appear” easy and straight forward has a lot of issues that could derail it in the real world. I went through TONNES of these issues with my earlier models so I know what to watch-out for but sometimes they can be hard to spot until you cut the model out and build it in the real world for the first time.

RC circuit for a Bibberbeest / vibrobot

ynze

Last February I posted a vibrobot project "Scary bots and Super Creeps", making vibrobots out of connectors, cable binders and electrical wire. The creatures are named "bibberbeest" in Dutch.
Making Bibberbeests with kids is a HUGE success at schools, parties and festivals (second video in this step)! In the past months I witnessed 500 kids (6 yrs and up) making their very own, unique Bibberbeest.

Now what is more fun than a Bibberbeest? A remote controlled bibberbeest, using a standard audio/video RC? And it makes the project a bit more challenging to high school kids like monster-marit and emilyvanleemput :-)
So what I needed was a receiver circuit for a standard TV RC that can switch on and off a Bibberbeest, working on 3 Volts max.

At first I was tempted to go the microcontroller way, inspired by Masynmachien's Wiebelbot. But then I bumped into this IR toggle switch diagram, which I eventually used with some small modifications. The circuit worked fine on a breadboard, but turns out to be a bit unpredictable as a Bibberbeest brain... So the circuit in this I'ble is not a nicely polished and tested end result. It's a proof of concept and hopefully an inspiration if you're into vibrating creature making...

SpaceFab: 3D printing and robotic assembly in space

Colin Dunjohn

SpiderFab, a series of technologies under development by Tethers Unlimited, Inc. (TUI), combines 3D printing and robotic assembly to build and create spaceship components and structures in orbit. The groundbreaking systems are being designed to enable on-orbit construction of antennas, booms, solar arrays, trusses and other multifunctional components, ten to hundreds of times larger than currently possible with existing technology.

TUI has recently received an additional US$500,000 phase 2 NASA Innovative Advanced Concepts (NIAC) contract, supplementing an initial $100,000 phase 1 contract awarded in August 2012 to develop the new technology.

A cardboard televisor (with arduino and LEDs)

Sparticles

Recently I saw a documentary about the history of the television.  And to my surprise they showed that there existed a mechanical television before the well known CRT televisions.

Those mechanical televisions or televisors were pretty smart and simple.
A CRT is simply an electron beam that scans a surface covered with a luminescent phosphor line by line. And the intensity of the beam is then directly proportional with the whiteness of that particular spot on the screen.

A televisor works in a very similar way. But instead of an electron beam, holes are used. Holes in a spirally pattern on a disk scan a small area as the disk rotates.  After that particular area an electrical lamp varies its intensity. Bright means a bright spot wherever a hole is located.

There are some videos on youtube from people who have built other televisors. With more lines and far better image quality than this one. (but they aren't made out of cardboard)

This instructable documents the build of such a very small 24 line televisor completely from scrap cardboard, scavenged electronic parts a laptop and an arduino.
The image quality is very, very low but it is built out of cardboard and it has only 24 lines.
But it was a fun build.
If you want a good display, there are much better alternatives, (pretty much everything is a better alternative).

NASA working on RASSOR robot space excavator

Jason Falconer

Recently we've seen preliminary asteroid mining plans from Planetary Resources and Deep Space Industries, but what about NASA? The government agency would like to do some excavating on the Moon, Mars, and asteroids, too – but it isn't in it for the profit. NASA wants to clear the way for construction projects and mine materials for use by astronauts, and is developing a teleoperated robot called the Regolith Advanced Surface Systems Operations Robot (RASSOR, pronounced "razor") to get the job done.

Scientists turn light into a tractor beam

David Szondy

From The Skylark of Space to Star Wars, no self-respecting science fiction spaceship would break orbit without a tractor beam on board. We’re still a long way from locking on to errant shuttlecraft, but a team led by Dr. Tomas Cizmar, Research Fellow in the School of Medicine at the University of St. Andrews, Scotland, has turned a laser into a tractor beam that works on the microscopic level.
Tractor beams are one of those things that seem on the far edge of what’s possible. The idea of a beam of energy streaming out that pulls things in is counter-intuitive, but scientists have been developing things that work like tractor beams since the 1960s and light manipulation has been tried since the 1970s.

Short Circuit project reuses unwanted kitchen appliances

Adam Williams

In recent years, repairing and upgrading electronics has largely given way to a trend of disposable gadgets which fill up landfills – especially with regard to home appliances like coffee makers and toasters. However, French designer Gaspard Tiné-Berès proposes to repair and re-use discarded and damaged appliances, with readily available reclaimed materials providing the necessary components, and the bodies constructed from cork.
