1. What is 3D printing?

3D printing is also known as desktop fabrication or additive manufacturing, it is a prototyping process whereby an real object is created from a 3D design. The digital 3D-model is saved in STL format and then sent to a 3D printer. The 3D printer then print the design layer by layer and form a real object. Read more..

2. 3D printing technologies

Quite a few technologies are capable to do 3D printing. The main differences are how layers are built to create parts. 

SLS (selective laser sintering), FDM (fused depostion modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. Selective laser sintering (SLS) and fused deposition modeling (FDM) use melting or softening material to produce the layers. 

This video describe how laser-sintering process melt fine powders, bit by bit, into 3D shapes.

The video belows explains the process of Stereolithography (SLA).

Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and colour capabilities.

 

3. The history of 3D printing

October 5, 2011 – Roland DG Corporation introduced the new iModela iM-01.

Sep, 2011 – Vienna University of Technology, a smaller, lighter and cheaper printing device has now been developed.

This smallest 3D printer weighs 1.5 kilograms, it costs around 1200 Euros.

Aug, 2011 – The world’s first 3D printed aircraft created by Engineers at the University of Southampton.

1.Sainsmart RAMPS 1.4
It is a Mega Pololu Shield, or RAMPS for short,designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. This board is mostly based on Adrian’s Pololu_Electronics and work by Tonok. Copper etch resists methods suggested by Vik. Also inspired by Vik’s work with EasyDrivers. circuit design based mostly on Adrian’s Pololu_Electronics Joaz at RepRapSource.com supplied initial pin definitions and many design improvements. Much inspiration, suggestions, and ideas from Prusajr, Kliment, Maxbots, Rick, and many others in the RepRap community.

2. Sainsmart Mega 2560 R3
Sainsmart Mega2560 R3 is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery. Arduino development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.

3. Sainsmart A4988 driver
This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

 

4.SainSmart Mechanical Endstop Switch

The mechanical endstop is a simple solution to a simple problem. We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruptors, we use a mechanical switch. If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. If you’re worried about reliability, you can sleep well at night. The switches we use are rated for 1 million operations before failure. Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch.

 

5.SainSmart 2004 Smart Yellow LCD Controller With Adapter

This Smart Controller contains a SD-Card reader, an rotary encoder and a 20 Character x 4 Line Yellow LCD display. You can easy connect it to your Ramps board using the “smart adapter” included.
After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

Project-SainSmart 3D printer built

The article is a person named Garrett Kendrick who used sainsmart 3D ptinter board to build his own 3D printer. Check out the process of this project.

Part 1

I have wanted a 3D printer for many years and done a lot of research. My first 3D printer was an Ord Bot Hadron that I purchased online for over $1500. While I love this printer design and high accuracy, I had a hard time shelling out that amount of money. I’m very happy with the printer, but wanted to find a way to make another (better) version for a much reduced price. That lead me to this build.

I received the SainSmart RAMPS 1.4+Mega 2560 R3 3D Print Kit. This kit includes the Arduino Mega 2560 microcontroller, Sainsmart A4988 driver board, 5 Sainsmart RAMPS 1.4, and plenty of interconnecting cables in a nice case. For the price, I was sceptical, but once it arrived (within 2 days of ordering) I was impressed.

I also received the SainSmart 1.75mm green ABS filament.

I found a good deal ($430) on an Ord Bot Hadron mechanical frame with orange accessories on eBay and bought it.

Part 2

I began printing the printable parts for my new printer with my old printer using the SainSmart green ABS. The parts came out beautifully!

Can a 3D printer print a 3D printer?

 

A starfish can reproduce without a partner. The creature loses an arm, and before you know it, you have another starfish. Think of the potential for the species to take over the world, if enough of them were willing to make that initial sacrifice of a limb.

Are 3D printers the starfish of the technology world? That is, can a 3D printer print a 3D printer? And if so, do we need to fear a runaway scenario? An attack of the killer 3D printers, if you will.

I did a little research (emphasis on word little) this morning, to see if I could find any examples of such self-replication; of an incipient master race of mechanical self-maters.

Nothing. Phew!

But surely, it must be happening. The hype of 3D printing has the things making just about everything else. We’ve all heard about the gun they can fabricate. And according to AskMen’s highly entertaining but somewhat questionable 3D Printers: 50 Things You Can Make, they can churn out meat, stem cells, jawbones, camera lenses, dishwasher parts, guitars, houses and even a Stradivarius violin.

So I return to my question. Can a 3D printer print a 3D printer? And what if one of these contraptions also started spawning not only more of itself, but starfish as well?

I’m frightened. I think I’m going to print a spaceship and flee to Mars. It might be a bleak existence – there’s no Twitter there that I know of. But at least there won’t be any 3D printers either. Not yet, anyway.

Absolutely Epic 3D Printed Atlas—are you ready for your new project?

Odds are, you’ve played either Portal or Portal 2 and thoroughly enjoyed yourself in the process.  And we can’t blame you – the game is incredibly unique and addicting!  One Portal fan took his love of the game to the next level by modeling Atlas in 3D (from scratch), printing the model, and painting it by hand.  Plus, he even used a 3D printed 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button as a base for Atlas.
