Designing a 3D Printable R/C Aircraft (Thin Walled, Lightweight Printing)

sahevaantaneja 

About two years or so ago, videos about 3D printed R/C aircrafts popped up on my suggested YouTube feed and since then I've wanted to build one of my own. I managed to find plans online and was intrigued by the immense amount of detail given to the internal structure, unfortunately, I did not have access to a paid slicer software capable of slicing such complex internal structures and the free slicer I was using was capable of slicing only the external skin/structure.
I figured that I might as well print the aircraft files I found online with conventional infills (hex, triangle, line, 3D gyroids etc.), a feature available with almost any slicer software out there. My printed aircraft turned out to be twice the anticipated weight and had a terribly high wing loading which made it fast as rocket.

The Synthfonio - a Musical Instrument for EveryoneFrancoMolina
What this is 

This is an easy to learn instrument, simple to operate, improvisation oriented and with an endless possibility of sounds (as a MIDI controller). It features 2 sets of keys, one to define chords and key signatures, and another one to actually play the notes. Whatever chord is pressed in the instruments neck keys will define the pitch of the keys on the instrument handle, similar to a guitar, violin, and other string instruments; with the added advance that this one is a smart device that can interpret the scale being played from a single notes or pair of notes.

The Lucien Yeomans “secret” that was almost lost.
Your developing world school needs almost-free machine tools?
Your developing world factory needs unavailable spare parts?
You need a complex part that is too expensive to have made?
Need to bootstrap a factory but only have a few bucks?
No problem!
You just need a metal lathe. Metalworking lathes are necessary to the production of almost everything but are very expensive. In 1915, special lathes made from concrete were developed to quickly and cheaply produce millions of cannon shells needed for World War I. Lucien Yeomans, the inventor, won the nation’s highest engineering award for it but sadly the technique was almost forgotten after the war. We re-discovered it as a way to quickly make inexpensive but accurate machine tools for use in developing countries and in trade schools and shops everywhere. We made modern construction practical by replacing the original poured, non shrinking metal with cement grout.

DIY Microwave Kiln | Fuse Glass in Your MicrowaveShakeTheFuture 

In this Instructable, we'll look into way to make a microwave kiln.
For those who don't know what is a microwave kiln, here is a quick introduction.
Microwave kiln is a kiln that you can put in your regular microwave oven.
It does not use a wire heating element or gas to heat up. Microwave kiln is covered with silicon carbide.
Silicon carbide absorbs microwaves and turns them into heat.
Microwave kilns are usually used to fuse glass.
You can turn broken glass into amazing jewelry.

DIY 3D Printed Dremel CNCNikus
When I got my first 3D printer I was extremely happy with all the new possibilities to create things but after some time I noticed the limitations of 3D printing. Plastic is easy to melt, sometimes it's not mechanically resistant enough and most importantly sometimes doesn't look good. Don't take me wrong here, I love 3D printing and I like plastic (except plastic waste) but there are things that look, work or feel way better when made out of nonplastic material. Imagine all your furniture made out of plastic. Sometimes I prefer wood, when I need strength, metal (mostly aluminum) is a way to go. That's where CNC milling machines are used. Usually, the cost of such machine is really high, most of the hobbyist, small makers can't afford such expensive equipment. That's why the idea of building my own CNC machine sparked in my head

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.

CIRCULAR CD SLIDE RULE

cparedes2302  

Hello Everyone!

Keeping it up with my math helping tools and after I finished my straight Cardboard Slide Rule, I decided to make another slide rule but of much easier and fast construction. I decided to go for a simple circular slide rule. Just as the previous slide rule, the intention is to have middle school students built their own and use it to get numeric ability. I know there are several apps that emulate a straight and a circular slide rule, but if you are using your phone it would be much easier to use the calculator instead of the slide rule. My dream is to have the students “thinking and reasoning” again instead of relying so strongly on technology.

The advantages of a circular slide rule is that the computing scales (C and D) of a 9.5 cm (3 3/4”) diameter tool are equivalent to a 30 cm (almost 12”) straight slide rule! So you can get a more accurate reading! The disadvantage is that as your scale is located closer to the center of the Slide Rule, the scale becomes very short and difficult to read.

PETG Print Settings – How to Find the Best Settings for PETGMiroslav Sarcevic  

PETG is short for polyethylene terephthalate glycol-modified. That could mean something to you if you’re into chemistry, but for the rest of us, it’s simply the most used type of plastic on the planet (in the form of PET). You can find it in plastic bottles, food containers, packaging, toys, kitchen utensils, and more common plastic products. In addition, this recyclable plastic can be injection molded, blow-molded, thermoformed, bent, cut, and in recent years, 3D printed.
We won’t go into the details of PETG chemistry in this article but will instead concentrate on 3D printing with it. Before we dive into printing tips, here are a few of the material’s characteristics:

• Glass transition temperature:  80 °C

• Density: 1.27 g/cm3 (which is higher than PLA and ABS)

• Resistant against most chemicals (such as acids, alkali, and solvents)

Ao contrário das Fresas 3D, as Impressoras não imprimem em 3D MESMO, porque o Extrudor só move uma camada de cada vez, toda ela, sem a possibilidade de estrudar, e descer, e subir, num acompanhamento duma superfície curvada.

Mas está-se já a começar a fazer REAL Impressora, já, já!

Achieve true 3D printing with non planar slicing

Teaching Tech

This is the most interesting thing I’ve done with my 3D printer in some time. Instead of printing in a series of 2D planes stacked up to form a 3D shape (2.5D), this non planar technique creates geometry with true 3D tool paths that can eliminate the steps often seen on shallow surfaces. Based on the amazing Masters Thesis of Daniel Ahlers and the University of Hamburg, this development can be tried yourself if you are willing to put in some time to setting it up.

In this video I’ll lead you through step by step on how to setup a virtual Linux machine on your PC, compile the custom version of Slic3r and then share with you my results. The future is bright and I thank people like Daniel Ahlers  and Moritz Walter for leading the way.

CNC Clamps 2mm (0.08 Inch) to 18mm (0.7 Inch)PatrickH101 

Clamps for holding down your workpiece on a cnc router. The
clamps are designed for holding down materials with a thickness of 2mm to 18 mm.
I designed the clamp using Fusion 360.
There are 4 different sizes for the bolt that goes through, M5, M6 or 1/4 inch and for a special request M8 (The M8 version is not tested but should work though the sliding distance is a lot shorter).
Best is to use a washer on top.
The actual foot to hold your workpiece can rotate to adjust to the thickness of your material.

What are we building?

Humans can't detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic field vector at a location is displayed on a small screen using isometric projection.

What is an Arduino?

An Arduino is a small open-source user-friendly microcontroller. It has digital input and output pins. It also has analog input pins, which are useful for reading input from sensors. Different Arduino models are available. This tutorial describes how to use either the Arduino Uno or the Arduino MKR1010. However other models can be used too.

Urethane Casting – All You Need to KnowAlex Haysler  

Urethane casting (UC) is a manufacturing technique allowing for low- to mid-range volume production. It successfully bridges the gap between alternative low-cost methods, which lack scalability, and injection molding. This method allows creation of production-like parts with high-quality, detailed features and cosmetic similarity both quickly and inexpensively.
UC is primarily aimed towards situations where the cost of hard tooling in aluminum or steel, such as for injection-molded parts, would prevent manufacture. UC can also be referred to as room temperature vulcanization (RTV), where the silicone mold is cured in ambient conditions.

Transparent 3D Printing – 4 Ways to Create Transparent PartsBenjamin Goldschmidt  

As you might have guessed, transparent 3D printing is printing a plastic part that you can see through. Applications of this technique vary from see-through vases to optical elements like prisms, art, or decorative pieces. While this might seem simple to achieve (buy transparent filament and print it), the reality is a bit more complicated. Before going into methods, we’ll need to learn about some of the science behind what makes something transparent: What is transparency?
Transparency, or the ability to see through an object, is controlled by how light passes through it. If light passes through an object without being redirected in a significant way (i.e. through a pane of glass), the object will appear to be transparent. In glass, the material is homogenous and clear, meaning that you can easily see through it. To mimic this property in a 3D printed object, we must adhere to the following rules:
Plastic material must be transparent to start with
Printing must limit the introduction of air bubbles into the part
The part should have a smooth surface in the desired transparent area

This CNC router can handle any length (within reason), the Y direction is only bound by your table length.

Width (X direction on rails) should always be the shorter axis and is recommended to keep the work area no larger than 4′ on this axis.

The Z direction (height) is best kept to a 3-4″ maximum for wood, with that being said, you can make the usable z length as much as you want you will be working from the bottom up, so go to town.

10 Advanced 3D Slicer Settings That Will Save Your Prints!

Accurate 3d slicer settings are one of the most important factors to achieve a successful 3d print. Even the most experienced makers often go through trial and error to find the 3d slicer settings that give them a beautiful print. In our last article Slicer Settings for Beginners – 8 Things you Need to Know, we went over the basic settings and how each one affects your print. Now we’re going to go over some of the more advanced settings that give you more detailed control over how your print comes out so you can take your 3d printing to the next level. An overwhelming number of you voted for Simplify3D as Top 3D Slicing Software in our 2015 Pinshape Awards which is one of the reasons we chose to use them as our example software for this post.  There are a lot of settings in this slicer program that give you a ton of control and provide faster, better quality prints. In one review, Simplify3D sliced a file in 55 seconds that took over 40 minutes to slice in another program!
