These 3D Printed Supports Can Take Hard Use, Thanks to Resin Filling

Posted on by

Liquid two-part resins that cure into a solid are normally used for casting, and [Cuddleburrito] also found them useful to add strength and rigidity to 3D printed pillar supports. In this case, the supports are a frame for some arcade-style buttons, which must stand up to a lot of forceful mashing. Casting the part entirely out of a tough resin would require a mold, and it turns out that filling a 3D print with resin gets comparable benefits while making it easy to embed fastener hardware, if done right.

Filling the inside of an object with some kind of epoxy …read more

Epoxy Fix For A Combusted PCB

Posted on by

When the Magic Smoke is released, chances are pretty good that you’ve got some component-level diagnosis to do. It’s usually not that hard to find the faulty part, charred and crusty as it likely appears. In that case, some snips, a new non-crusty part, and a little solder are usually enough to get you back in business.

But what if the smoke came not from a component but from the PCB itself? [Happymacer] chanced upon this sorry situation in a power supply for an electric gate opener. Basking in the Australian sunshine for a few years, the opener started acting …read more

Prusa Introduces A Resin Printer at Maker Faire NY

Posted on by

For one reason or another, the World Maker Faire in New York has become the preeminent place to launch 3D printers. MakerBot did it with the Thing-O-Matic way back when, and over the years we’ve seen some interesting new advances come out of Queens during one special weekend in September.

Today Prusa Research announced their latest creation. It’s the resin printer you’ve all been waiting for. The Prusa SL1 is aiming to become the Prusa Mk 3 of the resin printer world: it’s a solid printer, it’s relatively cheap (kit price starts at $1299/€1299), and it produces prints that are …read more

Incredible Atari 800XL Case Restoration

Posted on by

If you’ve been hanging around Hackaday for a while, you know that a large portion of the stuff we publish goes above and beyond what most people would consider a reasonable level of time and effort. One could argue that’s sort of the point: the easy way out is rarely the most exciting and interesting route you can take. We, and by extension our readers, are drawn to the projects that someone has really put their heart and soul into. If the person who created the thing wasn’t passionate about it, why should we be?

That being said, on occasion, …read more

Mechanisms: Abrasives

Posted on by

In our “Mechanisms” series, we’ve featured the fascinating bits and pieces that go into making our mechanical world work. From simple machines such as screws and levers, from springs to couplings, and even more complex mechanisms like zippers and solenoids, we’ve covered the gamut. But we haven’t talked about one of the very earliest mechanisms, captured from nature by our clever ancestors to do useful work like grinding grain and shaping materials into tools: grit, sand, abrasives.

Wearing Things Down

When we were kids, summers meant random visits from the ice cream man. We’d run up to the truck, swap …read more

Slipcasting Resin Prototypes

Posted on by

[Eric Strebel] doesn’t need an introduction anymore. If there is a picture of an elegantly designed part with a professional finish on our pages, there is a good chance he has a hand in it. This time he is sharing his method of making a part which looks like it is blow-molded but it is not. Blow-molded parts have a distinctive look, especially made with a transparent material and [Eric’s] method certainly passes for it. This could upgrade your prototyping game if you need a few custom parts that look like solidified soap bubbles.

Mold making is not covered in …read more

Review of the Moai SLA 3D Printer

Posted on by

It is funny how we always seem to pay the same for a new computer. The price stays the same, but the power of the computer is better each time. It would appear 3D printers may be the same story. After all, it wasn’t long ago that sinking a thousand bucks or more on a 3D printer wouldn’t raise any eyebrows. Yet today you can better printers for a fraction of that and $1,300 will buy you an open source Moai SLA printer as a kit. [3D Printing Nerd] took a field trip to MatterHackers to check the machine out …read more

What Would Sherlock Print, If Sherlock Printed In SLA Resin?

Posted on by

Resin printing — or more appropriately, stereolithography apparatus printing — is a costly but cool 3D printing process. [Evan] from [Model3D] wondered if it was possible to produce a proper magnifying glass using SLA printing and — well — take a gander at the result.

A quick modeling session in Fusion 360 with the help of his friend, [SPANNERHANDS 3D Printing] and it was off to the printer. Unfortunately, [Evan] learned a little late that his export settings could have been set to a higher poly count — the resultant print looked a little rough — but the lens would …read more

Enresoning An iPhone 8 Ring

Posted on by

The iPhone 8 was just released last week, and that means some people were standing in line in front of an Apple store for hours waiting to get their hands on the latest and greatest glowing rectangle. [Patrick Adair] had a better idea: he would stand in front of an Apple store for four hours, then do something productive with his new smartphone. With the help of a waterjet, some resin, a lathe, and some very fine grades of sandpaper, he created the Apple Ring.

Setting aside the whole process of actually acquiring an iPhone 8 on launch day, the …read more

The Illuminated Waterways of the United States

Posted on by

A recent convert to the ways of the laser cutter, redditor [i-made-a-thing] was in want of a project and — stumbling on some waterways maps on Etsy — launched into fabricating an illuminated map of all the waterways in the United States.

The map itself was laser-cut out of 1/4 inch plywood at his local makerspace. Thing is, smaller rivers and tributaries were too narrow at the scale [i-made-a-thing] wanted, so he ended up spending several hours in Photoshop preparing the image so larger rivers would be laser-cut — and not break off– while the rest would be etched onto …read more
