3D-printed Lightsaber Design Philosophy and Printing Tips For May the 4th, I designed a 3D printed lightsaber in commemoration of Star Wars day in collaboration with Ultimaker. There were many other designs out there, but none that I was really happy with. The examples I saw were mostly over simplified, impossible to print without supports, or difficult to assemble. I knew I wanted something more faithful to the original prop with better surface quality. So I set out to build my favorite design from the series. 4 vs 14 piece design I ended up making two versions of the Lightsaber, a 4 piece version which stresses ease of printing and assembly, and a 14 piece version that makes no compromise on surface quality. In this guest blog I will explore some of the design nuances, by comparing the two design philosophies represented by the simple and complex versions of the lightsaber model. This is an example of how printing direction could potentially limit your designs, but could be overcome by printing in multiple parts. Is it worth it?

Materials hold the key to higher growth in 3D printing Various 3D printer and additive manufacturing systems are already manufacturing parts, just not in the quantity that is possible. What’s holding back this technology’s potential to “disrupt manufacturing?” Design engineers will tell you it’s the lack of information and standards, particularly for materials. The print material used with 3D printer or additive manufacturing systems has been, and continues to be, a key to growth for this industry. For design engineers, the right material is key to every design. Also, design engineers need a lot more information about material performance before they will specify it for wider manufacturing application. How do secondary processes of finishing (painting, bonding, and so on) affect the material? Then, there should be manufacturing guidelines for each of the 3D printing, additive manufacturing processes. Information on material properties must be sent out to the design community so that they know what they are working with.

Dingdong merrily I’m high, on ASB and nylon…… | Econolyst A few years ago, I gave a presentation at a rather dull conference to a bunch of very traditional engineers. Given that the conference was organised by the Gauge and Tool Making Association, I guess I shouldn’t have expected a great reception to my ‘Additive is the future’ speech. In fact, I think the concept of using 3D printing to make Santa Claus recession proof left most of the audience looking like Jeremy Paxman trying to comprehend the workings of an Objet Machine. The Makerbot mixtape – 3D printed MP3 player However, fast forward a few years and here we are in 2012 with a 3D Printed winter wonderland on our December high street. This week, I was lucky enough to visit both the Makielab pop-up shop on Regent Street London and the very next day, by a twist of British Airways scheduling fate, the new MakerBot retail store in Lower Manhattan New York. So what did we find? Look into my eyes Makie-dolls – cute but sinister! What a difference a day makes! 2 days retail stock of printers

- Large Format 3D Printer with 4x Synchronous Extruder 3D Printing Greater than 470 x 435 x 690mm build Area The Beast's enormous build area allows users to print objects that have never before been possible on a printer with such a low price point. Our hope is for "The Beast" to make many previously unattainable projects and prints possible and to make it accessible to as many makers, inventors, DIY enthusiasts and artists as we can. High Speed and Simultaneous Printing The Beast's ability to simultaneously print 4 identical objects or groups of objects will enable small scale manufacturing capabilities at a fraction of the cost of 4 individual 3D printers. The Beast effectively cuts print times by 4 when printing simultaneously. 4x Synchronous printing combined with a high speed rail system and Bowden extruders means "The Beast" is capable of producing prints upwards of 10x faster than other FDM (filament type) 3D printers. 4x Printing also enables the user to print 4 of the same object/s at the same time with different colours or materials.

We need to keep printer manufacturers away from filament : 3DGenius One of the things people new to 3D printing always ask is: “How much does it cost to make a print?” Without fail, they’re always surprised by how cheap it is. Show them a 3D-printed thimble and they’ll be lightly amused; tell them it cost only a few pennies to print and they’ll see the whole 3D printing process as a much more viable opportunity. What people are expecting is the sort of tactics promoted by traditional printer manufacturers – the likes of Epson, Canon and Hewlett Packard. They’ll readily sell you a cheap enough printer, but you’ll pay a fortune for the ink to run it. Because 3D printing filament is sold generically, rather than customised for a single printer, printer manufacturers don’t have a stake in it and filament makers are subject to market forces, keeping prices down while having to maintain the quality of their product in order to gain repeat sales. But there is a dark cloud on the horizon. So what constitutes a “regular-sized print”? Share it!

Business rate deferral A scheme allowing ratepayers to defer some of their 2012/2013 liability was introduced by the Government last year. This scheme allowed business ratepayers to defer up to 60% of the increase (equivalent to 3.2% of the total liability), and repay the deferred amount in 2013/14 and 2014/15. When setting the new multiplier amounts for Business Rates, the government has to use the inflation figure from the previous September. In September 2011, inflation was 5.6%. The Government announced that it planed to allow business ratepayers to defer up to 60% of the increase (equivalent to 3.2% of the total liability), and repay the deferred amount in 2013/14 and 2014/15. Ratepayers who have found an additional increase amount, (as shown as a balance brought forward into this 2013/2014 charge), means they have applied for this scheme to be applied to their business rates accounts.

Replicator Warehouse | All about 3d printing My first Marvin... | Maker Tale | 3D Hubs Talk So I've just joined 3D Hubs and printed my first Marvin! He is such a cute little fellow, and I wanted to make sure that he would look the best he could on my keyring. I am a jewellery designer, so I am quite used to working on a small scale, even in 3D printing. I used my Ultimaker Original +, which I finished building at the beginning of January. Since then I have been printing a lot, trying to tweak the settings for the organic and cellular shapes I usually print. Perusing the forums for advice has been amazingly helpful, and the most pertinent tip I learned about was to consider the model when choosing a resolution, as higher res does not always mean a better print. Layer Height: 0.1mm Shell Thickness: 0.4mm Retraction: enabled Bottom/Top Thickness: 0.6mm Fill: 0% Print Speed: 20mm/s Temp: 210C Bed Temp: 70C Filament Dia: 2.85 Flow: 100% No Support or Adhesion I also enabled combing and set the z-hop at 0.075

Starter Kit: Autodesk 3ds Max This tutorial is for Autodesk 3dS Max 2010: How to export a STL design file using Autodesk 3DS Max STL designs are good for all 3D materials. 1. Remove extra vertices Select all the vertices and use the Weld function in the Edit mesh modifier to remove any double ups. 2. 3ds Max will triangulate your mesh when you export. 3. Select all faces and use Unify under Surface Properties to make sure the normals are facing the right way. 4. Use STL Check in the Modifier List to check your model for errors. Here’s a little support on how to fix errors that STL Check has picked up. 5. Choose File, Export (non-native). 6. After you have clicked Save, make sure the STL Settings are set to “Binary” (the object name is not important) and click OK. You’re now ready to... Upload issues? My file is too big Your 3D design file must be less than 20mb. I get a non-manifold mesh error, but I can’t find where it is Use STL Check to find and select non-manifold mesh edges, faces and vertices. Too hard? top
