What can be 3d printed?

Basically, anything you want.What can be 3d printed

Any solid object you can print out like sunglasses, milk jug, a boat propeller pretty much any solid object you can print out which is awesome.

There are some famous 3d printers like MakerBot or Ultimaker. But these laser printers are expensive and they’re really high quality.

They both are good for beginners but they’re probably too expensive for people to start out. But there are some different options you can use that might be a little bit less known but still get the job done.

Global3d labs printer are best with little investment. They have category according to your budget.

 

CAD Modelling-

Let’s start with 3d CAD model a three-dimensional model on the computer of the object which you want to print. After designing CAD model we export that as a dot STL file share lithography file and from there we can import that STL file into our slicing software.

CAD Modelling

In the slicing software, we can edit the layers, the tool path, the temperature, the colour and how fast you want to print.

After editing send that code that it to slicer which makes a dot g-code file off to the 3d printer.

Click print button on the printer so that it makes to our object that we made in the CAD model.

Just like magic printing a button and you can get any physical model you want.

You can also download CAD file online and create a three-dimensional object.

 Types of 3D Printer

There are two main types of 3d printing

FDM- Which is the most popular one fuel deposition modelling and SLI with this Stereolithography.

 

FDM-

FDM printers are the most popular because it works on an additive process, it’s not that messy, it’s not that hard to use and they are pretty cheap.

Prints up to 20-micron layer thickness that’s the lowest that most printers can go which is really really thin. You’re getting it nice and smooth prints with FDM.

It is an additive process so it uses a spool of filament plastic and it extrudes that through a hot nozzle at 195 degrees Celsius or around that temperature.

It extrudes it through a cone-shaped metal piece called the hot end and extrudes that out into a really really small thin strand.

The printer moves it around in three dimensional XY and z planes and squishes those layers on the bed on top of each other.

 

Stereolithography (SLA)-

SLA printing layers aren’t as thin but you’re still gonna get an amazing print quality because of less moving parts than FDM printers.

SLA

SLA printing uses a projector or a laser to hardened resin as a boat platform moves up. The prints upside down actually so it depends on what you want to print.

SLI is also more expensive and FDM is cheaper. So that’s why most people go with FDM printers.

 

RepRap Printer-

There’s a RepRap printer which works on an additive process.

The big metal part in the middle is the extruder and it has a big bed size of about eight or nine inches that’s the average size of the RepRap printer in the middle.

Here we have a Parmaan 200 printer which is still FDM but it uses two motors and three carriages to move the nozzle around and up and down on a rectangular bed.

We have an SLA printer, these are more expensive but the quality is a lot better but they don’t have as many materials as FDM printers.

There are two ways you can find models you can either make it by CAD software or download it online.

Most popular ones in a 3d printing industry are Google Sketchup in artists using 360 these are really easy software’s you can export STL file to send to your slicer software and they’re really easy for beginners to learn.

The area where 3D printing will impact first of all is in the production of large-scale but simple objects that everybody uses – Dr Adrian Bowyer.

RepRap-derived printers will be so useful that people will want to make new copies of the machine themselves.

It can print out just over half of the parts needed to build a new RepRap machine.

Printing out an object using RepRap technology is very simple, users download the model for the item they are interested in.

Insert it into one of the open-source software packages like simplify 3d and send it to the machine and hit print.

 

Filaments-

There are more different filament types. Most people print in PLL because it’s less toxic.

There is ABS from which people make Legos out if it’s a harder tougher plastic which is also harder to print.

3D_Material

There’s nylon filament, there’s carbon fibre, there’s TP which is flexible, there’s wood, metal. PVA materials can be printed from a 3d printer, so wood filament glow-in-the-dark come from PLA – which is cool.

So if your printer can print PLA most likely it can print wood or glow-in-the-dark.

 

How to find models online?

This is what a lot of people do for just a quick model there’s Thingiverse which is the most popular one.

People can just find quick models they can download them directly as an STL file send them to the slicer software and print any object.

I’ll definitely recommend going there first instead of making your own in your CAD software.

 

Slicing Software-

There are many different slicing software but I recommend three – the most common one called MakerBot desktop now is the slicer software for MakerBot printer.

Slicing Software

Kira is for Ultimakers and Simplify 3d is what most people use for RepRap printers.

First, you are going import your STL file into your slicer software and your slicing software is going to export it as a dot G code which we will erect into the printer

There are single and dual extruders on printers.

Extrude the filament out of the nozzle so similar series can only print in one material type but dual can print in two material types.

So your model can have two colours which are pretty cool.

 

 3D Printer Heated Bed-

3d printers should have heated beds which helps the material stick to them. It won’t pop off in the middle of the print so there are glass beds.

The glass beds have a nicer bottom surface but painters tape beds are usually able to stick the print down easier.

You can replace the painters tape but in glass, you can’t really take it off which gets pricey.3D Printer Bed

After a while infill is how much plastic is inside of your model, so I recommend anywhere from 10 to 35 percent infill but you can go up to 100.

It depends on how many times your heater goes around the perimeter of the object.  So one layer is going around once, two is going around twice and bottom layers are how many layers of solid material print at the bottom of your object.

I recommend about two to four bottom layers which work best bridging and overhang. Most printers can print about 45 degrees and over that, it will start to overhang.

So object orientation and your selector software is very important. You want to use as less support as possible it helps print faster and the surface will be a lot nicer. Use the least amount support and overhangs as possible.

As you can see 3d printing is an awesome technology as keep experimenting and keep researching.

For any kind of question please do comment. Thank You.
