  1. Or you can get a poster-print of your picture. Not too expensive these days. Some printshops offer large scale prints around here for reasonable prices, and places that offer photobooks usually also offer poster prints.
  2. I only know their chrome, but I do know that the underground matters very much. You can spray it over any high shine surface and get a chrome effect, the underlying colour will effect the outcome in a subtle way. Don't see why this wouldn't work with aluminium. But I highly recommend doing some test pieces first!
  3. In that size you'll probably be better off working with a paint that gives a slightly rough finish. I don't know the real parts, but from my work experience with casted parts they are not extraordinary rough - the surface is as rough as sand on a 1:1 part. Because that's what's usually used to make the form.
  4. That is probably not going to happen, at least not legally. Most designers do not permit selling of their printed product! So it is not legal to offer this as a service. The printer would need to buy a commercial license to print and sell the miniatures. Some designers do offer these licenses, most don't. I never saw a shop that bought such a license to make some money. If you provide the file and pay for the printing as a service you circumvent this problem.
  5. It is also a good practice part for 3d modelling. Simple geometry, can be done with very few operations and is a nice usecase for the pattern tool.
  6. One thing is sure - I'll get me a Saturn if money allows. Which shouldn't be a problem.
  7. There you go. A few little brave moves gave you a nice and way more realistic model. I think you can be proud of your work.
  8. Mike, why would you remove the thread? Here's quite a bit of valuable information in the posts above. Maybe just rename it.
  9. Yes, it is kind of a consumable and at least on the mars is a sparepart that can be bought seperately. I'd think this is the same with the photon. With the mars the cost is at about 40€. They might even be interchangeable. I don't really know how long they last, mine has probably about 100 hours of printing time and is fine.
  10. Mark, Ali - no rocketscience going on there. If you have an STL file on hand the next step is slicing and preparing your model. What you need to do is fire up the software coming with your printer or chitubox. Load the model and place it on the virtual buildplatform. Then let automagically create supports or do them yourself when you become more experienced. Safe (!), then let it slice. Slicing is the process that translates the 3d model into layers and is basically the same process that happens with shapeways. Only this time there might be no warnings and autocorrections if you have too small or badly placed parts. Think of it as shapeways "print it anyway" option. Save the sliced file as well - this is the one that goes to your printer. Mark, I don't know if the mentioned slicers have a Mac version available, but might very well be. I've compiled a list of software from user input, there are some slicing options in there: Jan
  11. I can see where they are coming from but to be honest the two methods are pretty much the same. Both involve lowering the bed so that it is just pinching a sheet of paper evenly across the surface. The Mars is slightly easy as it appears to have a bed levelling function which drives the bed onto the paper. It still has grub screws (two in fact) which you loosen then hit bed level then tighten. It seems the bed is sprung so will settle evenly if the grub screws are loose. So a bit easier, I agree but they are essentially the same method. The Photon has a little more room for error. if the photon is not spring levelled it IS harder to do and comes a lot down to experience. On the Mars it is trivial. You losen the 2 screws, place the paper, lower the platform automatically and tighten the screw again. No fiddling with a tad more pressure here, a tad more there. I now can see where the adhesion problems on the photon could come from. Still - both are great machines for very little money. With the current photon offering I'd be tempted to get me a second one...
  12. Elegoo Mars and standard Photon are basically the same machines. Main difference is in packaged slicing software and cover. The cover of the Mars is very basic but functional. The benefit is you can reach into the printer from all sides without being constrained by sidewalls like on the photon. To me this is a huge plus. The slicer for the photon is probably a variant of chitubox and can be used with chitubox, while the mars uses chitubox right away. The glove information needs to be clarified. No matter the color or the price - DON'T USE LATEX. This is the message. Use Nitrile gloves.
  13. Wow. Finally again a supercar that isn't just a bag of jokes. I am not really sold on the styling with the fan, but I do absolutely love the approach and the way Murray sells it. This is some serious engineering and really showing off the love for that. I absolutely love the see-through tunnel and that enginge is gorgeous. Cosworth have done some serious work there. I really was sold the moment he started speaking wheel sizes and metal over carbon. Thank you for sharing. I'm a teen again and want to hang posters over my bed!
  14. Finally we arrive at Fusion360 I start with some preparation steps first. I build some sketches on the origin planes that contain known dimensions. Most important is the wheelbase as this is the easiest thing to scale the reference pictures to. So I set this up first. Also I do rectangles on all 3 planes to give the overall size of the subject plus a 3d box. Everything I model must stay within these constraints. Make sure all sketches are fully defined. Under no circumstances would you want undefined moving sections. This is key to professional CAD work. Last thing I'll do is placing the pictures of my subject. I like to push them away from the origin planes, but I know some folks do keep them there. It comes down to personal preferences. Next is blocking in known pieces. This usually means the wheels - the diametre is typically well known as is the width. Placing is also defined by the wheelbase and width of the subject. So here we go: Note that for every part I create a new component. Also I do work with linked copies if I need multiples of a part: I copy the component and simply insert it. Then place it where it belongs in the design. This creates a copy of the original part, that immediately changes if you edit something on any of the copies. If you don't want that behaviour you have to explicitly tell Fusion to break the link. With all easy to do parts placed it is time for the next step - working with the imported pictures. Every major geometry is blocked in. To do this use the straight on views, this makes sure your sketches end up where you place them. The trick (to me) is not to get lost in detail. This stage is all about getting the basic geometry right. Nothing else is important here. All parts can be refined at later stages. All I want for now is ensuring the overall shape is correct and working. Sometimes there is a point where you can't get any further with simple sketches and extrusions. This is what is hard for me: Working with sculpting tools and or splines. Fusion gives you two alternative ways to deal with freeform parts: Define surfaces by surrounding splines. This gives maximum control but is hard if you are not working from blueprints. Or work in the sculpting environment, which I did here to achieve the hood. It is a simple form, so probably was a good starting point to learn. It still took me two days and several attempts to get a clean mesh and smooth surfaces that at least look somewhat like the original. In the end I started from a Quadball primitive that I pulled and extruded until I got to the point you see here: And this is the structure I ended up with. Nice and clean, as I'd expect it. The form needs to be refined and the front part needs to be stretched, but we will get there. This is where I stand at the moment. Everything from now on will be slower progressing as I can only work on this in my spare time which is basically nonexistent at the moment.
