How to 3D Print Hollow Objects – Simply Explained

Pranav Gharge 

Have you ever wondered whether hollowing out a model is a good idea or not? Well, the simple answer is that since 3D printing is a volume-based production technique, there’s almost always a benefit to some degree of hollowing out of a print. Hollowing can save you printing material, time, and money, and of course, potentially improve your prints.

In this piece, we’ll discuss hallowing prints in general for FDM, SLA, DLP, and LCD (resin) printing. Then, we’ll focus on the three main ways to hollow out your prints: with a slicer, vase mode, or a modeling program (we choose Meshmixer as our example). And finally, we’ll go over some considerations for when and how much to hollow.

Bending steel with plastic 3D printed toolsStuff Made Here 

I've been wondering if 3D printed tools could possibly bend steel. It seemed possible unlikely. I designed and printed several tools which are used on a hydraulic press to bend and form steel sheet metal. This particular tool could be made by CNC machining the tools from metal but 3D printing it is much faster and easier

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.
Be sure to check out the build notes on all of the enlarged images!

Evezor: Open Source SCARA Robot ArmJeremy S. Cook

Per this project’s Kickstarter video seen below, when 3D printing first jumped came into the mainstream, many people thought they could now make anything they wanted, perhaps even many of them to sell with no human interaction. While true in some sense, these machines do require human intervention between prints, and can take a very long time to produce useful parts. Additionally, some designs may require a different tool, such as a laser cutter or CNC router. That, of course, means more space and money, and still there is the issue of machine tending.

SCAD to STL – How to Convert SCAD Files to STLBenjamin Goldschmidt 

SCAD and STL files are two common file types for 3D design applications. SCAD stands for “Solid Computer Aided Design”, and the file format is used to describe 3D objects. It was pioneered by a software called “OpenSCAD,” which is a free CAD software for designing 3D objects. STL stands for “stereolithography” and is a popular file type to use with slicers for 3D printing.
The main difference between these two file types is in the way the models are described in code. In STL files, the 3D model is created using a “tiled” set of triangles along the surface of the object. This creates a fully 3D object. In contrast, SCAD files design an object using mathematical relationships. For example, a cube-like object can be described using its length, width, and height. This type of design can be useful for printing objects such as fractal art on objects.
Because the geometry used by STL files is more capable of conforming to complex designs, you may find you want to convert SCAD to STL. Lucky for you, there are two really easy ways to do this.

Dan Gelbart : How to Build Stuff

Al-Hala

Dan Gelbart has an excellent and well-presented series on YouTube on machines and prototyping. It`s a short course on how to build stuff aimed at students, researchers and others who are not machinists by trade. It`s applicable to prototyping and limited production with enabling technology in 18 parts, which I’ve listed links to below. Note: the chapters were obviously shot out of sequence, as there is referral to `as we`ve seen before` when we have not. It`s not that bothersome.

How to Make a 18650 Li-ion Battery Pack!

Nematic!

18650 Li-ion cells are a great way to power Projects. Which provides a nominal voltage of 3.7V which is not sufficient for most of the application for let's say you want to power a BLDC motor with an ESC which requires 9V to start. So we need more voltage which can be achieved by connecting them in series. So in this tutorial, I will show you how you can make a 18650 Li-ion Battery Pack with a BMS circuit and all the things you need to know before you built one!

Recreating an Antique Divers Helmet From Foam
LostWax

I love the ocean. I can sit on the beach all day just watching the waves do their wavey thing. Sadly, I happen to live in the middle of the Canadian prairies. No ocean to watch here. But there's always the world of make-believe, and what better way to get in the ocean vibe than with an amazing deep sea diver costume. I created this costume pattern to try and recreate the feel of the classic "Mark V" dive helmet which has become an iconic image of divers and the sea. It was used by the U.S. Navy from 1916 until 1984! Let's make one of our own.

Cardboard Bender
nml235l

A tool is something that makes life easier and more convenient. I have got a rather huge mass of cardboard (a cause of a new furnishings :-)) and appropriate number of ideas to make something with it (Bag for Containers). One problem is bend operations. Cardboard plates have a multiply layer (as usual) so I get clumsy splits during bending. To prevent such behavior I decided to flatten cardboard according the bend line. At this moment we get situation for a ... NEW TOOL. How to make flattening along the path? Certainly, using a one of the ancient inventions – the Wheel. We need only move the wheel (roller) along the path on cardboard surface with giving insignificant pressure. This principle we use in home preservation to connect bank and cover (or let's remember about the roller-machine for road construction). Concept of a tool is very simple: roller (wheel) and handle – nothing more.

RF Signal Generator
Milen

The RF signal generator is a must to have tool when playing with radio receivers. It is used to tune a resonant circuits and adjust the gain of different RF stages. Very useful feature of the RF Signal generator is its modulation capability. If it can modulate the frequency amplitude or frequency makes it non replaceable tool for RF design works.
Some time ago I have designed an AM modulator, which could be used for such purposes. It works fine in some cases, but it has the disadvantage to be not able to work as standalone device. It requires additionally power supply module and two signal generators - for the RF carrier frequency and for the modulating signal. This makes it inconvenient to work with it outside the house. I decided to create an RF signal generator working as fully functional stand alone device. Instead to base the architecture on the modern DDS chip, I decided to use the analog approach. As a basis I have chose an existing RF signal generator published here. Similar design is described also here. The credits for this design go to their authors. I repeated mainly the first design adding additional digital frequency counter instead the not very precisely radial scale analog calibration.

While pop cans have a deposit in my state, other canned non-carbonated drinks like lemonade do not. The recycling center is a bit out of the way from me, so I wanted to give reusing these cans a try first. There’s a lot of flexibility in materials and methods in this project, so I’ve tried to highlight substitutions as best as possible.
Note: this project involves sharp edges and cutting tools. If you are looking for a project suitable for children, consider using aluminum foil as discussed in “Substitute Materials.”
