This is a short tutorial that shows you how you can make metal parts, at home, in less than 1 hour, in a few easy steps.

If you like this instructable you can support me having a look at my IndieGoGo campaign here; you can now get your LumiPocket 3D Printer, a project that I started one year ago as a simple hobbyist, and now has became (hopefully) my full time job.

Safety is important!

Casting metal is serious business, and very dangerous. Even when using proper safety gear, and observing all necessary precautions, serious accidents can still occur. Lack of proper safety gear, unsafe surroundings, or unsafe procedure increase both the likelihood and severity of accidents.

Step 1: Required Materials

Pewter is a malleable metal alloy. It has a very low melting point, that makes possible to cast it with just a propane torch. Today, pewter is used in decorative objects, mainly collectible statuettes and figurines, game figures, aircraft and other models, (replica) coins, pendants, plated jewellery and so on.

In this guide we will use:

  • Lead free pewter
  • Ladle
  • Propane torch
  • LumiPocket 3D Printer (you can get your here, hurry before the campaign ends!)
  • Industrial Blend FunToDo resin
  • Handheld Infrared Thermometer

<p>The title is misleading. I thought this was about 3D printing with metal, but it's not. It's about casting with metal, using 3D printer to create the mold, which isn't anything new.</p>
<p>Hi, I choose the 3d printing with metals since it involves 3d printing to make metal parts in very little time. What you refer to is called &quot;direct metal 3d printing&quot; or simply &quot;metal 3d printing&quot;, and THAT would have been a clearly misleading title.</p><p>And I have written clearly that you can have similar results with another 3d printer based on the same technology, with the same resin or one with the same technical specifications.</p>
<p>the fact remains that you are NOT 3D printing with metals. u are 3D printing with plastics.<br>if your title is not '3D printing with plastics', then you are misleading.<br>hope yr not gonna advertise yr business the same way, or u will soon have a lawsuit brought against you by non-stupid ppl</p>
<p>ohwait, you dropped yr product details, this IS advertising</p>
<p>I am going to have to agree with you on that. It kind of feels like an advertisement for the indiegogo campaign sadly.</p>
The guy is trying to start a company, give him a break
Hi, thank you! By the way, your works are really inspiring! We are in netherlands now for the dutch design week!
<p>I agree. I have no experience with either and read this. I think a title like:</p><p>Use a 3D printed mold to cast metal (Pewter) </p><p>is more accurate. There is wiggle room on the actual title.</p>
<p>Thanks for the instructable - some of us may not know as much as your detractors, (myself for one), so it's always nice to see how some different things can be made, and made in different ways! One day I may need this knowledge, and then I will have it.</p><p>BTW, Since a CNC machine costs in the tens of thousands (the one where I worked in a granite shop cost between 1/4 and 1/2 a million dollars), I think the comment that suggested you use one was probably just a little bit out of line &lt;]:&gt;)</p>
<p>Pro Tip: If you coat the inside of the mold with very fine (baby) powder you will get better results and the object will come out easier.</p>
That is the most usefull advice from the whole instructable. Thanks man
Great Instructable, hopefully one day everyone will have a 3d printer , then purchase , download plans and print there new eyefone. <br>* Commentators unless you've attempted this project yourself . Please keep your intimidating self glorifying suggestions to yourself
<p>You could print the positive image and then make a mold from a material that can take the heat.</p>
<p>Go Marvin! ;)</p>
<p>This is great thinking.</p><p>But you should use a CNC milling machine, make ceramic moulds(ceramic can hold high temperature) and then cast it. The plastic was ruined from the heat, but you can cast &quot;cold&quot; materials instead( resin, silicone, cement, plaster...).</p><p>Good luck :-)</p>
<p>Hi, the plastic was ruined because I had only available at home a lead free version of pewter with a melting point of 240&deg;C, and the mould was made with Industrial Blend Resin that is tested up to 250&deg;C, so I was really close to its limits. In the guide I suggested using a low melting point pewter with a m.p. of 138&deg;C so the resin will show no damage at all!</p>
<p>You also could use a cermaic coating(spray/paint) on the mold. It's cheaper than buy/make another machine. I don't know what th eresult would be but you can test it.</p>
<p>Very interesting process! Thanks for sharing!</p>
