    Infra Red Plastic Material

    Thanks muadib3d for your reply. We also just got a response back from and injection moulding company from China and they have advised a charcoal grey tinted Polycarbonate material. We will test a sample with a prototype electronics circuit to confirm the transmission is suitable. Many thanks for your recommendations. Ronnie

    Infra Red Plastic Material

    b-b-b-b-b-bump. Having no luck with this even after extensive google searching.
  3. Hi I am working on a product casing similar to a TV remote control and need to specify a material for the casing that will transmit and receive and Infra Red signal. The material will need to have properties similar to ABS in terms of strength and durability and suitable for injection moulding. What I would like to know is, is there a particular Infra Red plastic material, or would ABS be specified with a particular colour and tint? Typically Infra Red windows on tv remotes and similar products is a dark transparent plastic, tinted either red or green. Thanks in advance for any response. Ronnie
  4. Came across this article with tct magazine, Ogle model and prototypes built a prototype for a students final year product. Excellent model by Ogle of course, but I thought this was a bit of a cop out..? http://www.oglemodel...ion-results.php Just remembering a good 6 weeks as a student of blood, sweat and tears making my final year prototype, which included RP, milling, lathe, vacuum forming, fabrication, electronics etc. excellent educational experience. This article came across a bit like- 'oh here, you make it'...? I may have this wrong, just putting it up for discussion. Perhaps the emphasis on this course/project is not the model making.

  5. Hey Newbie How about trying a pen, paper and a ruler! Or spend some time to learn how to use autocad. Ronnie

    Do I Really Need A Prototype?

    Hi Congratulations on you new idea. I would have no problem sharing a new idea with a manufacturer, on the basis you have found someone you trust, and have put in place and NDA, 'non-disclosure agreement'. If it is a unique idea that no one has ever produced, then as Dastardly Dave mentioned, it may be a good idea to protect your intellectual property. Contacting a company such as http://patentfactory.co.uk/ would be a good start and they can do a search for you to tell you if you idea is unique or in anyway protectable. However, you can spend a LOT of money and time protecting your intellectual property with patents. Another option is to get your idea to market fast and sell. If anyone later copies your idea, you were the original and got there first. (chances are even with a patent it will still get copied..!). 3D CAD is more than adequate to share with a manufacturer to gain information on costs for mass producing your product, a prototype is not neccesary. However, as a matter of the design process, it is crucial to produce a prototype to prove out your design and test it works. It would be naive to jump straight into making tooling to mass produce a product without making a prototype. Infact, many manufactures would insist on a prototype being made first, and may even offer this service as part of their package. The prototype can also be used as a communication tool used for marketing, sales and product packaging shots, all this is increddibly important, because you need to be determining market interest in your product and generating pre-sales for you product before the investment of mass producing it. Rapid prototyping is a generic name of a method for making prototype models involving a computer controlled machine that makes your model. As opposed to more traditional hand-based model making techniques. Rapid prototypes are made directly from 3D CAD data, and are quick to produce, very accurate and can provide a model very representative of the final mass produced part. There are also prototyping methods that mimic rubber parts. Feel free to send me a PM if you would like to know more.

    Matching Pantone Colours In Paint

    Suprised at no responses... no one else painting prototype models out there? Update>> The response I keep getting elsewhere is... pantone is a printing colour system and the pigements used to make the colours are different than that used by paint manufacturers to make their paint colours. If you go to an automotive/industrial paint mixer they will have charts which guide them to mix up a pantone colour using their set of base pigments. However, as their pigments are different to the pantone system there can be inconsistencies and some of the vivid colours come out less vivid, in particular bright pinks, which will come out dusky and a bit murky. So.. it is possible to get a reasonable match and I have found a couple of good companies, but the results are not always spot on. Which is surprising, as pantone make a booklet of plastic coloured chips for the communication of colours for products. However- how can I accurately communicate a pantone colour on a prototype, say for example, for use in a packaging shot or in a presentation? I rang directly Pantone the self-proclaimed authority on colour and asked if they could help. They said the guy who could help had gone home early (at 3pm) and offered to call back but never did. ronnie
  8. Hi All, Where I am working we have just ordered an Objet 24 rapid prototyping machine. We are a small company on a budget and didn't buy into the expensive water jet cleaning system (£2k+) to remove the support material. Looking to hear responses from anyone with experience of cleaning these type of polyjet models and perhaps could recommend what alternatives you use. We are lead to believe running under a tap stream and using toothbrush will remove support OK. Plus also a bath of caustic soda to remove any tackyness. Cheers Ronnie

    Best Laptop For Solidworks.

    The company I work for have used this company in the past - They specialise in CAD workstations for the design industry. Just viewing the laptops will give a good idea of specs and they will be able to help you with advice if you call them http://www.cad2.com/workstations/quadro-laptop.html May be worth looking here if you require any software: http://www.software4students.co.uk Ronnie

    Radii On Rib Ends

    Hi gameface, Not sure if the crease line is meant to be there or not? Sometimes when I do patterened ribs like this I model the shape to be removed as a seperate body, adding fillets as required, and then pattern the body and subtract them from the main body. Another method would be to project a split line of the rib shape you want onto the main body (as per your pdf), then delete the face and then model the detail in. Ronnie

    A Real Atom

    Imran- Well presented- polished looking work! Are you pleased with the outcome? I think the shape and proportions are quite different and 'out' there. Being a concept car and in particular with a different power source- seems quite fitting to shake things up a bit! Why not? I've also heard of the idea of nuclear power cars- but only non-working mock-ups, around the 60's era, Ford Nucleon. Was this for a transport design course project?- your original post didn't say any background info- just pictures. Ronnie
  12. Russel Hobbs did a thermo-color kettle where the material colour changed according to the temperature. http://www.insidedgw.com/episode-985/ Maybe worth picking one up second hand (ebay?) and give it a good analysis. Ronnie

    How To Handle Criticism In School?

    Hi Indy, Just to add- us designers can be a sensitive type of folk. Critism of our work can leave us feeling upset, miserable and sometimes outraged! When we do our work we put our skill, passion, creativity and personal designer's intuition into what we do. Sometimes, despite our best efforts- this doesn't always work out right, and others like professors, consumers or clients may not agree or like what you have done. I think the key is to not take it too personally, and instead be objective and seek to understand why what you have done is not well received - and to engage and understand with whatever is not quite right. Your professor isn't attacking you personally, just giving constructive critism about your design work, to help teach and improve your skills as a designer. Over time you will build up a harder exterior to such feedback and be more pragmatic about it. Until then, as cyberdemon noted.. beer always helps. Ronnie

    Bottle Engraving

    Looks good to me.. as Ceri said- makes sense for it to follow the contour of the surface. I've never used wrap for text- Normally I would make a plane nominal to the surface for the text then offset a surface of the bottle the depth of the engraving, extrude text and cut with surface, combine text with bottle. There's more than one way to skin a cat.. G'luck ronnie
