  2. Hi! Using some software online i have downloaded some sections of the UK as a topographic map, and customized them slightly using SolidWorks. Currently its just white but I'm going to print it in Multicolour. Im unsure though if it is too complex to be 3D printed? Changes to the embossed text and wall thicknesses are ok, but the land contours themselves are more complex, and I'd like to know if this is feasible before continuing. model (1) and model (4) Combined Landmass only.STL
  3. Kurt is at it again! Fantastic design as usual. Glad to see that all of the pieces fitted together
  4. Hi Joon, Thank you for getting in touch. One of our support engineers will take a look at your 3D file and contact you via email shortly. Best regards, Fabian
  5. Printed in steel in separate pieces, with a polyamide insert to provide the necessary spring actions. I drilled and tapped the holes and screwed it together. The steel pieces were finished in polished black, polished natural and unpolished natural. The polished black is especially nice. The printed parts were flawless and the finishes were great. Designed in SketchUp Make. Here's a video of it in action.

  8. Hi iMaterialise Puzzles fans, Seven Gear Loop is a gearing mechanism of seven gears in a loop. Usually, a loop of gears requires an even number of gears, as otherwise the loop gets stuck. After all, the gears should turn alternatingly clockwise and counter-clockwise (anti-clockwise). However, it works for this gear set, as the seven gears are not in the same plane. See also the 9- and 11-gear versions by Blake Courter. Question: can a similar five-gear loop exist? Watch the YouTube video. Buy the puzzle at my iMaterialise Shop. Read more at the Non-Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
  9. I'm going to print the 3mf file with 'Multicolor gloss'. Can someone analyze my 3d model and check if it is able to print? Or, can you tell me what should I modify? 001.3mf

  12. An article from 2015: 3-D-printed car could hit streets next year. Chris Woodyard, USA TODAY 4:48 p.m. EST November 12, 2015 http://www.usatoday.com/story/money/cars/2015/11/10/3d-printed-car-local-motors-swim/75530830/ Several companies have come out with what they call "3D-printed" cars, but none have 3D-printed the most important part, the engine. This would be difficult to do with an internal combustion engine, with its high temperatures, multiple moving parts, and high tolerances. But it shouldn't be too difficult with an electric engine. In fact considering there are now miniature 3D-printers on the market for the home, an amateur could be the first to produce an entire, scale-size, 3D-printed car. And then it could be scaled up to produce a full-size, working, fully 3D-printed automobile. This would revolutionize the industry, obviously. The two most difficult parts would be the engine and the transmission. This video shows how you can make your own simple electric motor: How to Make an Electric Motor at Home - YouTube. http://www.youtube.com/watch?v=0p2QTE26VOA Looking at the steps in the video, it appears they could all be accomplished by 3D-printing.

  13. GE has mass produced via 3D-printing a metal nozzle tip that would have been difficult to produce using other methods:An Epiphany Of Disruption: GE Additive Chief Explains How 3D Printing Will Upend Manufacturing. Jun 21, 2017 by Tomas Kellner http://www.ge.com/reports/epiphany-disruption-ge-additive-chief-explains-3d-printing-will-upend-manufacturing/ But what I really find interesting in this article are some comments GE's additive manufacturing head Ehteshami said about what he see's for the future of 3D-printing: and: From the way I interpret what Ehteshami is saying, it mirrors something I've been thinking. You can imagine not just cars being fully 3D-printed, but entire airplanes, tractors, construction vehicles, refrigerators, air conditioners, and everything else called "durable goods". But this would mean nearly all manufacturing jobs would be replaced by 3D-printing machines. That is a major economic disruption. Not only that, but all these would become much cheaper. Would the companies that produce them even be billion dollar companies anymore? Bob Clark
  14. Desktop Metal says their method for metal 3D-printing is superior to the laser sintering for volume production of metal parts because of the laser methods slow rate of deposition. DM claims 100 times faster production rates than the laser method. But since this high production rate comes from using many more print heads, it seems to me you could get the faster deposition rate with the laser method by using, say, 100 copies of the lasers. Laser 3D metal printing commonly uses a 200W laser. So to scale this up 100 times would require 20,000W. The cheapest cost I've seen for lasers were by manufacturers in China in the $15 per watt range. So 20,000W would cost in the range of $300,000. Most likely the lasers would be the primary cost for the machines, so call it ca. $600,000 for the full machine able to duplicate the Desktop Metal production rate. One laser 3D metal printing company also suggests use of wirefeed rather than a powder bed can increase the production rate and also reduces the cost of the material: VIDEO: Is Wirefeed the Future of Selective Laser Sintering? James Anderton posted on December 19, 2016 | http://www.engineering.com/AdvancedManufacturing/ArticleID/13955/VIDEO-Is-Wirefeed-the-Future-of-Selective-Laser-Sintering.aspx Near the end of this video they also suggest scaling the laser up to the 15,000W range could bring the production rate to the level of other commonly used metal production methods.

  15. I'll posts below some posts I made to other online discussion forums on fully 3D-printing electric cars. My intention is to show why I think it is currently feasible. The posts mention Desktop Metal, but only because that was the only metal 3D-printing system I was familiar with at the time. I'm convinced that any metal 3D-printer could 3D-print at least a scale-size electric motor. Then once the feasibility of that is demonstrated the obvious next step would be to 3D-print a full-size electric motor, and thereafter the final step of fully 3D-printing the entire full-size, electric vehicle. Therefore, I wanted to ask you what are your rates for renting time on your metal 3D-printer? And what would be the rate if I submitted just the design for a part to be metal 3D-printed and you printed the part for me? Any feedback both positive and negative on its feasibility is appreciated.

  16. Hello. Just signed up. My background is in pure mathematics but I'm fascinated by the new capabilities being developed in technology. I'm of the opinion that much of what has been done in traditional manufacturing can be done by 3D-printing. I want to discuss on the forum the possibility of an entire automobile being 3D-printed. Bob Clark
  17. Hi Alice, Regrettably, we can't assist you in this matter. It is important to know the exact surface and the sphere with its dimensions in order to proceed further. Since this is a math related question with functions involvement, my advise would be to browse the web for a solution. Kind regards, Ivan
  18. Please feel free Fabian. And thanks!
  19. After testing the bigger printing sizes for Aluminum (announced on May 24) for several weeks, we re-updated these sizes again today. As of now, the maximum printing size in Aluminum is 440 x 220 x 320 mm. The pre-May 24 printing size was 250 x 250 x 295 mm. This means that the maximum printing size for Aluminum increases by 68% in the end. You can learn more about Aluminum 3D printing (incl. demo pieces, technology videos, and design guidelines) here: https://i.materialise.com/3d-printing-materials/aluminum
  20. Hi Ivan, I understand, would you have a contact at Materialise who could give me more information? Thank you in advance, Alice
  21. Perfect timing, well done! Do you mind if we share this on Twitter (we will include a link of course)?
  22. Hi Alice, Here at i.Materialise we provide a 3D printing service of designed parts. We can advise you on printing feasibility, materials, finishing options or advise you on how to change the design to make the model suitable for 3D building. Unfortunately we do not design or complete the projects, thus I can't advise on the mathematics origins/estimations of surface fitting. As much as I'd love to help you, I can only recommend to look up for this information on multiple blogs, posts or have a 3D engineer assist you. Regards, Ivan Manhushev
  23. Today's pickup. Cyclo - pendant in silver - height 26 mm. It's already in my shop.
  24. Hi Ivan, Thank you for your quick reply. The sphere will indeed be 3D printed but my question concerns more the mathematics behind the "surface fitting" of the analytical sphere construction. I need to know this to justify the use of this tool. I hope this gives you a better understanding of my question, Looking forward to hearing from you Kind regards, Alice
  25. Hello Alice, Thanks for your question. For me to move in the right direction, could you please clarify if you are currently designing a 3D model to be printed afterwards? Often the solution is based on the intended surface a sphere will be fit to. Looking deeper into this, the issue might be more math related. Kind Regards, Ivan
  26. Hello, To justify my design process, could you please tell/explain me which method is used to best fit a sphere to a selected surface? Is it the least mean square algorithm? Thank you in advance for your support, Regards, Alice
  27. That frame came out fantastic! The painting is really cool too!
  28. Hi Jens-Uwe, Thanks for your feedback. If you need to order many small parts in Polyamide or Alumide, a grid container can reduce prices a lot. You can learn more about this here: https://i.materialise.com/blog/grid-container/ Other than that, we have a list of some other tips and tricks for price reductions here: https://i.materialise.com/blog/5-tips-to-make-your-3d-prints-cheaper/ Best regards, Fabian
  29. Thanks, this has helped - but the pricing is way off. Best regards, too!
