Casting Metal Directly Into 3D Printed Molds

Posted on by

Casting metal and 3D printing go together like nuts and gum, and there are no shortage techniques that use the two together. Lost PLA casting is common, and sculptors are getting turned on to creating their works in plastic first before sending it off to the foundry. Now the folks at FormLabs have turned the whole ‘casting metal and 3D printer’ thing on its head: they’re printing sacrificial molds to cast pewter.

There are two techniques demonstrated in this tutorial, but the real winner here is printing a complete sacrificial mold for pewter miniatures. While this technique requires a little …read more

A Great Way to Make Quick and Easy Knobs

Posted on by

Here’s a great way to quickly and easily make attractive and functional knobs with no tools required. All you need is some casting resin (epoxy would do in a pinch), a silicone mold intended for candy, and some socket head bolts. With the right preparation and a bit of careful placement and attention, smooth and functional knob ends are only minutes away. Embedded below is a short video demonstrating the process.

These may not replace purpose-made knobs for final products, but for prototypes or to use around the shop on jigs, clamps, or furniture they certainly fit the bill. With …read more

How to Do Beautiful Enclosures with Custom Fiberglass

Posted on by

There are times when I feel the need to really make a mess. When I think of making messes with a degree of permanency, I think of fiberglass. I also really like the smell, reminds me of a simpler time in 8th grade shop class. But the whole process, including the mess, is worth it for the amazing shapes you can produce for speaker pods and custom enclosures.

Utilizing fiberglass for something like a custom speaker pod for a car is not difficult, but it does tend to be tedious when it comes to the finishing stages. If you …read more

Hackaday Prize Entry: DIY LCD based SLA 3D Printer

Posted on by

Resin-based SLA 3D printers are seen more and more nowadays but remain relatively uncommon. This Low Cost, Open Source, LCD based SLA 3D Printer design by [Dylan Reynolds] is a concept that aims to make DIY SLA 3D printing more accessible. The idea is to use hardware and manufacturing methods that are more readily available to hobbyists to create a reliable and consistent DIY platform.

[Dylan]’s goal isn’t really to compete with any of the hobbyist or prosumer options on the market; it’s more a test bed for himself and others, to show that a low-cost design that takes full …read more

A Big 3D Printer Built Using The Power of Procrastination

Posted on by

When we wrote about [Dan Beaven]’s resin printer a while back he enthusiastically ensured us that, thanks to the recent wave of attention, he would finally finish the project. That’s why today we are covering his entirely unrelated 2 cubic foot print volume FDM printer. 

As we mentioned, [Dan] is no stranger to 3D printers. His addiction has progressed so far that he needs bigger and bigger parts, but when he looked at the price of printers that could sate his thirst… it wasn’t good. We assume this is the time he decided to leverage his resin printer procrastination to …read more

3D Printering: Smartphone Resin Printers Actually Work

Posted on by

Last spring, the world saw something amazing. It was a device that would revolutionize the planet, save the world, and turn your smartphone into a 3D printer. Kickstarters aren’t known for selling themselves short. I speak, of course, of the OLO 3D printer, later renamed the ONO 3D printer, ostensibly because of a trademark dispute.

While filament-based 3D printers are extremely capable and slicing software is only getting better, resin-based printers are able to produce prints of nearly unparalleled quality. If you want high-resolution objects and fine detail, a resin printer is the way to go. These resin printers, however, …read more

Design and Testing of the Form 2

Posted on by

Formlabs makes a pretty dang good SLA printer by all accounts. Though a bit premium in the pricing when compared to the more humble impact of FDM printers on the wallet, there’s a bit more to an SLA printer. The reasoning becomes a bit more obvious when reading through this two part series on the design and testing of the Form 2.

It was interesting to see what tests they thought were necessary to ensure the reliable operation of the machine. For example the beam profile of every single laser that goes into a printer is tested to have the …read more

Robots With 3D Printed Shock Absorbing Skin

Posted on by

MIT’s Computer Science and Artificial Intelligence Laboratory, CSAIL, put out a paper recently about an interesting advance in 3D printing. Naturally, being the computer science and AI lab the paper had a robotic bend to it. In summary, they can 3D print a robot with a rubber skin of arbitrarily varying stiffness. The end goal? Shock absorbing skin!

They modified an Objet printer to print simultaneously using three materials. One is a UV curing solid. One is a UV curing rubber, and the other is an unreactive liquid. By carefully depositing these in a pattern they can print a material …read more

Hackaday Links: July 24, 2016

Posted on by

Right now HOPE is dying down, and most of the Hackaday crew will be filtering out of NYC. It was a great weekend. The first weekend in August will be even better. We’re going to DEF CON, we’ll have people at VCF West, and a contingent at EMF Camp. If you’re going to EMF Camp, drop a line here. There will be Hackaday peeps wandering around a field in England, so if you see someone flying the Hackaday or Tindie flag, stop and say hi.

Raspberry Pi’s stuffed into things? Not all of them are terrible. The Apple Extended keyboard …read more
