3D Printing Molds For Thermoforming Short Runs: Quick, Easy, and Inexpensive

 

Businesses call owners of Massivit 3D printing solutions to bring their most creative ideas to life. Now they can call when they need multiple copies of displays, signs, or props.

Massivit 3D makes short run molds for thermoforming possible—and even profitable.

Thermoforming is a cost-effective process when you need multiple copies of the same product. Take a mold, place a thermoplastic sheet on top, add heat and a vacuum and voilà! The sheet takes the form of the mold. Lather, rinse, repeat until enough copies are created.

CAM Lite

ALL3DP

Estlcam is a computer-aided manufacturing (CAM)  program that allows users to turn 2D drawings and 3D models into machine-readable G-code. This brilliant project was created by Christian Knüll, and its popularity has skyrocketed since it debuted in 2014. Perhaps the most attractive characteristics of Estlcam are its simplicity and low price.

If you’re a beginner in CNC milling, you’ve probably been frustrated by the complexity (and ungodly prices) of many CAM programs. Estlcam solves these frustrations by presenting users with an extremely intuitive user interface at a price of around $60.

The program sticks to the basics. Simply import a 3D file (such as an STL) or a 2D file (such as .dxf, .svg, .png, .gif, or .jpg), generate toolpaths, export the G-code – which is referred to as a “CNC program” in Estlcam – and start cutting. In this article, we’ll guide you through Estlcam’s basic features and provide tips on settings along the way.

The Secret to a Perfect Hot Glue Mold

SophieBdoesart

I've been making molds for a while now, but I often found myself frustrated by the high costs of materials. I love the quality that silicone molds like Smooth-On give, but I wanted to find a cheaper alternative for small casts. Hot glue was the obvious choice for me because of its price, its flexibility, and its incredibly quick cure time. The one major problem with hot glue is that it sticks to almost everything. I needed to find a mold release that would fill any small pores in the positive, allow the object to de-mold easily, and be as inexpensive and readily available as hot glue to avoid defeating the purpose. I tried everything. Oil, petroleum jelly, even some Smooth-On mold release as a test but none of them worked well enough to not damage the molds when I removed the object. I didn't figure it out until we had a power outage and I was digging through my collection of scented candles. The liquidy, melted wax was perfect for coating objects. Hot glue doesn't stick to it but it goes on thin enough to not obscure the details of the mold. Here's how I finally got the perfect hot-glue mold:

Spring Making / Wire Bending Machine 

jiripraus

Well, this machine is not only about making springs. It is a wire bending machine capable of bending 0.8/0.9/1 mm wire into any 2D shape. But yeah, the coolest thing I was able to make with it so far was the spring. How cool is that?
The main goal was to make it quite precise. Other DIY wire bending machines are not very precise and their bends tend to have quite a big radius. I like to work with nice sharp bends!
The second goal was to make it as easy to build as possible with commonly available parts and components. All the structural parts are 3D printed and all the metal parts are available in most of the hardware stores.

How to Create a Large 3D Printer Using a Smaller 3D Printer - "Project Locus"redhatman  

From those that own 3D printers, to those who simply are just curious about their capabilities, one topic that comes up rather frequently is the idea of "Printing another 3D Printer". Now this may not be 100% possible when considering components such as the electronics, however, nearly every 3D printer today in the open source community utilizes to some degree, 3D printed parts in it's construction. From fan mounts to spool holders, a person can spend a few minutes searching the web, and likely find a suitable design to use on their own printer. This has proved to be very useful, especially for those who love to build, modify, and design their own machines.

Benchtop Micro Milling MachineHonus  

This is a micro sized benchtop mill that is suitable for milling small parts in soft metals such as Aluminum and Brass. While it is a manual mill it wouldn't be too difficult to convert it to CNC by adding suitable stepper motors and a CNC controller. 

The travel specs are:
X axis- 150 mm
Y axis- 75 mm
Z axis- 150 mm 

This design uses off the shelf assembled linear slides and 80/20 Aluminum extrusion for simple assembly and accurate alignment. The beauty of this design is its modular nature- you can make it any size you want and it's super easy to build.

Rocket Boat

makjosher 

Every year in October, some friends of my parents have gotten together at a cabin next to a small pond. As a kid it was one of my favorite times of the year, as it meant I got to hang out with my two favorite cousins and one other friend. One year we got the idea to build a simple wooded boat and attach some model rocket engines to it. We built the boat and launched it from the dock. That boat only went about 6 feet, but an annual tradition was born. Over the next few years we built several more boats - most were dismal failures. Eventually, my brother decided to have a go at building a boat and his boats were considerably more successful. We gradually increased the rocket thrust and even added a second rocket stage. Our most successful run made it around half way down the pond before the boat lifted off the water and tumbled out of control. This year I decided to build my first boat in quite some time - this is the story of that boat.

Smartphone Controlled Cat Laser

Ikkalebob 

I've been wanting to start exploring the world of microcontrollers and programming for some time now, so I came up with this simple project which uses an app called "Blynk" to allow you to wirelessly control an Arduino board through your wifi. Now obviously the end result isn't the most practical device you'll ever build, but this was a great way for me to learn the fundamentals of programming Arduino and it can help you to learn too.

I've tried to arrange this project in an easy-to-follow format so it's ideal for someone who knows nothing about Arduino, but there's a lot of room for tweaking and improvement in my code that would allow more advanced users to get some use out of this project too.

This is a project that's been done before a few times, but I wanted to add something new by giving the system remote control functionality.

DIY Magnetic Hand-Saw Guide - Extremely Accurate Cuts!

Yonatan24 

I think handsaws are WAY better than circular saws for many reasons, but I always come across one problem: I'm never able to saw perpendicular, aka square, at a 90° angle. You can see the example for this here.

I have (finally!) received the saw that I won back in the 2015 Shelving Contest with my Ultimate Magnetic Pegboard. It's extremely sharp, beautifully made, and has a really comfortable handle. However, it is very thin, and doesn't have any aligning support on the top, so it bends really easily while sawing.

A well known solution for this is a Miter-Box. I've bought one, but it just doesn't work. Instead of having the sides hold the saw, I just saw into the plastic...

One day I was daydreaming a bit: "If I take that magnetic dovetail jig that I saw in one of Jay Bates' videos, and align it differently, will I be able to use it for sawing at 90°, perpendicular, and square to the wooden board that I'm sawing?" So I do a quick search and: "Wait, WHAT? It costs 50 DOLLARS?"

"OK, nevermind. I'm making my own!" I decided that I'd make myself a magnetic guide, which ensures that the cut will be square in all directions. Alternatively, you can modify it, and use it for dovetails, miters, or anything else.

CNC Drum Plotter

lingib 

This instructable describes an A4/A3 plotter made from a section of plastic pipe, two BYJ-48 stepper motors and an SG-90 servo. Essentially it is a flat-bed plotter rolled up into a drum.

One motor rotates the drum while the other moves the print-head. The servo is used to raise and lower the pen.

This plotter has a number of advantages over a traditional flatbed plotter:

significantly smaller footprint

only requires one linear guide rail

simple to construct

cheap

An on-board interpreter accepts the gcode output from Inkscape.

Communication with the plotter is via a bluetooth link.

The plotter is compatible with the CNC Graphics Tablet described in my instructable http://www.instructables.com/id/CNC-Graphics-Tablet/.

While not a precision instrument the accuracy of this plotter is satisfactory for its intended purpose of transferring watercolor outlines on to paper.

Upcycle Brushless DC Motors From Printers

ossum

If you are at all interested in robotics and electronics you will probably have disassembled an old printer or two (if you haven't, I highly recommend it, there are always interesting parts, and you can learn a lot about how the experts put electro-mechanical machines together). If you have taken a laser printer apart, you will likely have come across brushless DC motors, which range in size.

These motors have some pros and cons, obviously it varies between printers, and the functions of the motors within the printers, but I have found the following to be true most of the time

3D Router: When a CNC machine is overkill

Paoson Luthier 

The idea arose after dealing with the difficulties and loss of time in preparing for certain CNC jobs. Sometimes I spent more time preparing for the CNC than the work itself. With this manual router, you can make holes or mill very fast. A universal 43mm collet makes it very versatile and you can change the milling tool to drill very fast.

There are certainly lots of wooden router table and CNC router plans floating around in cyberspace. What makes this project noteworthy are the feature set and the cleverness of how it’s all put together and designed for maximum versatility. This router table can be used as a 3-axis drill press, sanding station, a 2D router, and you can do simple shapes 3D milling via a reference model. Using a series of accessories, you can also cut circles, straight-cut squares, and cut to a 2D reference model.

The uses of this tool are varied. I am a guitar maker and my plan consists of devising several templates of guitar bodies and necks to be made with the 3D Router, without switching on my CNC. Besides, it can also be used for other woodwork tasks. I have tried to make a design which can be easily built, with rather simple and cheap parts.

Overall dimensions: 800mm high, 740mm width and 700mm depth.

Useful dimensions: 425mm in X Axis, 535mm in Y axis and 185mm in Z axis.

Super flexible double curvature surface - laser cut plywoodkofaktorlab 

Carl Friedrich Gauss distinguishes between three types of curved surfaces, single curved - neutral (cylindrical), and double curved - negative (hyperboloid) and positive (spherical).
Curved surfaces are very attractive, especially negative double curved surfaces, but also very complicated to perform. What’s interesting about them in constructive terms is the increase in stiffness and load capacity as the surface is bent in one and two directions.
In a small book DIGITAL Gehry Material Resistance Digital Construction (Bruce Lindsey, Bitkhäuser 2001) writes that if flat piece cost one dollar, single curvature piece cost two dollars, double curvature piece cost ten dollars. This is true for all materials wood, metal, plastic, glass, concrete ...
It is immediately clear why some engineers are crazy about double curved surfaces and are constantly trying to find a method that can simplify and cheapen the process.
From time to time I search the Internet on that matter. One day I stumbled upon the wooden book covers that can be done on a laser cutter, with interesting technical solution of the spine; wooden board is slit in such a way that can be bend like rubber.

Super recycled benchtop power supply

juaspo

Working with electronics you are bound to need different voltage sources for your projects. So having a good and reliable benchtop power supply is way, way, waaay easier and more convenient than having to combine batteries in different ways or trying to find a power adaptor that can deliver just that right amount of voltage.

Now, obviously you can easily get one of those pro made power supplies by trading a sh*t load of money for it. But in my opinion that is both less fun, easier, more safe and less recyclingy...(that should be a word) and also it costs more... and will make a less interesting instructable... unless you tend to review them...

Anyhow this is not going to be a full super detailed instructable on how to mod a PSU to a benchtop PS since there is a ton of those all around but rather give some tips and inspiration and show how I did mine.

Making Custom Threaded Inserts (3D Printing)

PeterM13

Many times when you print a downloaded part, the fastener holes or hex recesses are too tight. Other times, the type or size fastener that the design requires is just not available, which happens a lot here on Maui. The Item pictured here is a spindle bracket to replace the motor on a ShapeOko CNC router. Since the fasteners on the original machine were metric fasteners, the new bracket was designed the same. The problem was that the 3" long clamp bolts were not available at all. The through holes were of the proper size to be able to accept a length of 10-24 TPI all thread. That meant I could substitute a hand-made bolt assembly for the designed fasteners, but the recess for the nuts on the back side were too small to accept the 10-24 nuts. My solution was to double nut the threaded shaft and use heat to insert the nuts into the recess forming an insert that had a threaded shaft attached.
