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.

Ponham as vossas criações, 2D ou 3D, neste programa, Esticam, e ele deita cá para fora o G-code nessessário para os 2 casos...
É bom!







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:

Algo de altamente Artesanal, cmo fazer um Ukelele, a partit dum Tronco!




Soprano Ukulele (From a Log!)

Rob Salmon

There was a glorious old apple tree in my garden. It was right in front of my kitchen window, blocking all of our light... but it would be sinful to cut down.

October 2014 - The tree was laden by a burdensome overload of apples. It was a barely noticeable, mildly windy day, and down came the tree! As, the clean up began, I cut the tree into manageable pieces. There was one piece, that for some reason I liked the look of, I kept it in my shed, and said, one day I will make something out of that.

Fast-forward to 2018. I had bought a cheap set of carving chisels, and started to look at this log, and imagine what fantastical shapes I could reveal, when I started to carve.

I had never made a musical instrument, at this point, though I have since had a number of adventures. As I threw my tape across the log, my mind began to wander. My daughters 4th Birthday was impending, and I had been considering getting her a Ukulele. A quick google to check the size of a soprano ukulele...it looked like there may be a ukulele hiding in the log.

It is almost impossible to write a "step by step" for this project, without volumes of text, as such the photos on each step do a lot of talking. Furthermore, this instructable is really about providing inspiration for others for future projects. The instructable is generally written in the first person, I have no doubt that there are better ways to do some of the steps. There may even be steps or advice that is just plain wrong! - Its really about inspiration ...and fun. For the most part (except for fretting!) this is simply good fun, with a happy biproduct of a working musical instrument!

Aqui, trata-se duma Fundição para a vossa Oficina, eléctrica, com um Lid Switch, e que vocês fazem em casa.

120v Metal Foundry With Lid Switch

IJustLikeMakingThings 

I have been wanting to build a metal foundry for some time but was torn between going electric or propane until I came across This Instructable that was electric but was only 120 volts. All the other builds I had seen had been 220 volt builds or used electric elements from stoves but I wanted to use120v and a heating coil. I also liked the ability to precisely control the temp because then I could also use it as a heat treater. I came across This Build which had a nice design and some great tips that I utilized in my design. I was able to use aspects of both of these designs to create my foundry.

I tried to design this to use tools that most makers should have or give you options for those with limited tools. At most, this can be made with a hacksaw, file, snips, and drill.

I wanted to include some safety measures to protect myself. I added a switch to cut the power if I lift the lid to prevent any chance of contacting the live heating coil wires. I also added a cover over the electronics, including the heating element wires. All other designs I saw had exposed wires and nothing preventing contact with the live heating coils.

Home Built 4x8ft CNC Plasma Metal Cutting System

Customfabricated

What is a CNC Plasma Cutting System? These are computer controlled machines that can cut through any electrically conductive material (steel / stainless / aluminum / copper). The machine takes a 2D computer generated sketch and translates it to a computer numerical control (CNC) system that is coupled with a Plasma Cutter. The Plasma Cutter uses an electrical arc and compressed air to cut through the conductive material.

I designed and built this system in my personal shop utilizing several off-the-shelf components along with some custom fabricated assemblies.

Check out the following steps for a detailed overview of my custom CNC Plasma build!

Plastic Brick Compressor

Rehaan33

Background

This is my IB HL Design Technology major project. It is a product that takes plastic waste and transforms it into bricks. This product was specifically designed for rural (developing areas) environments and as such, requires no electricity to operate. The production of plastic bricks in these communities can help to not only clean up their environment but also educate them on the plastic issue, provide sustainablebuildingmaterials as well as promote social entrepreneurship in these areas.

This is, unfortunately, a very specialized project as requires access to quite a few resources as you might notice when you read through this Instructable. If you have any questions, please do not hesitate to ask them in the comments, and lastly, please vote for this instructable in the Plastics Contest if you enjoyed it!

Write in Braille With B.E.E! - DIY Braille Embosser

alatorre

Braille as a form of communication has always interested me greatly- so when I saw a contest about making Tools, I took it as an opportunity to develop an idea that I had been thinking about for the past year or so.

When researching how Braille worked and the tools that were used to generate said writing, I was surprised to see how expensive they were. It was as if there were two price ranges:

Very expensive and very precise (we are talking upwards of $2000)
Very cheap and not very precise
For Braille to be read quickly and easily, there are a series of dimensions one must follow (such as the distance between bumps, from the edge of the paper etc.). As such, I thought that a tool that would be very useful would be one that was cheap and even Open Source, whilst also capable of stimulating the interaction between the blind and those who aren't.

With that in mind, our team developed B.E.E (which stands for Braille Embossing Experience).

Our goal was to create a tool for embossing which could be made at home, would cost less than $5 to make, and could be carried inside a backpack without disrupting any usual movements.

This Instructable will detail not only the way to construct your own B.E.E unit, but also all the design process and work that it took to arrive to where to product is today.

Wooden LEGO Duck

BrittLiv

I have been obsessed with LEGO ever since I can remember. Those small plastic building blocks were definitely one of my favorite toys as a kid and I still buy LEGO sets from time to time, even though I am in my thirties now (I have also written three Instructables that have to do with LEGO so far).

As a new mother my son is definitely still too young for the small LEGO pieces, but he has a bunch of LEGO PRIMOS.

I have known for a few years that the LEGO company has also produced wooden toys and wanted to buy one. Sadly they are rare and most of the time really expensive. The wooden LEGO duck is by far my favorite toy of that line, but I was never able to buy it. So I finally decided to make my own. The bonus of making one myself is that I can give it to my son and not worry about its value.

The special thing about it is that when it moves it opens and closes its beak. I hope that you will have as much fun with it as I do.

Robot Cat

By 陳亮

I am playing with the well known Strandbeest many years ago and really love the artificial life. And then I tried Trotbot, but sorry about not yet built Wadevag suggested Strider :P


Two years ago, I start saw many robot cats and dogs projects on the web. They works, walk well and can do some pose. The only shortcoming is it does not look like a cat or dog.


So I try to build my own robot cat. The main target are look like a cat, act like a cat.

The Secret to Cutting a Ball On a Manual Lathe

Arnold's Design

It's true. They don't show you this sort of thing when you take machining courses. Here I show you how a ball turning fixture works. There are a lot of different types of ball making fixtures, but this one is unique because it allows you to offset your cutting tool so that the rest of the fixture doesn't get hit by spinning lathe jaws.
