Beginner Guide for 3D Printer Leveling

09/03/2019
by JGAURORA ADMIN

Overview

By now if you’re a beginner, you’ve had prints lift up or warp on the build surface. Filament may stick to one corner of the surface and not to the other or your head may be grinding into your build surface. So what is wrong? Most poor prints can be diagnosed as an unleveled build surface. For those of us without an auto leveling machine this can be a true pain. Leveling is also the most common mistake made by beginners and advanced users alike. Weather it’s outright forgetting to perform the process or someone not following the proper leveling technique. So how do you a beginner level your bed?


When Should I Level?

Level your bed every time before starting a new print even if you just finished a print and the next print uses the same settings. Because when you pop a print off the bed, this will cause the printer to loose its settings. Always recheck your level before starting a print. So how do you level your printer?

Steps for Leveling

  1. Ensure your printer is on a level surface.
  2. Find a piece of A4 paper. This is the approximate distance the nozzle should be from the bed once homed and leveled.
  3. Tighten all your leveling screws and then home your nozzle.
  4. Now move the nozzle to the first leveling point, get your nozzle as close as possible to the bed and put the A4 paper underneath the nozzle.
  5. Manually adjust the bed until there is slight resistance on the paper from the nozzle.
  6. Repeat this step in all the points of your bed.
  7. A SUCCESSFUL FIRST LAYER is VITAL to a successful print. The last step is to start your print and stay with your printer until the first layer is down.  If the print head lays down an inconsistent layer or even starts to rip the layer up, stop the printer and relevel. Do not leave until you are sure you have a good first layer. 


Conclusion

If you follow these steps you will find that over time your prints will be consistently better and like anything else you will learn your own techniques for getting better prints. Please beware though leveling is an art and you will see many failed prints. Most of all don’t get angry, instead take a deep breath and look at what is happening on the bed. Most of all have fun!

3D Printing for Beginners – All You Need to Know to Get Started

08/20/2019
by JGAURORA ADMIN

As we’ve already mentioned, FDM 3D printers use spools of filament to build parts. The stuff is basically a thermoplastic specifically engineered to be melted and cooled while maintaining its structural integrity.
Filaments for 3D printing usually come with two different diameter options: 1.75 mm and 3 mm (or 2.85 mm). Apart from the diameter, filaments also come in different spool sizes. A closer look at the market reveals that the most common sizes are 500 g, 750 g, 1 kg, 2 kg, and 3 kg.
One of the best things about FDM 3D printers is that they can work with a large selection of filaments. Here are just some of the different types of filament which are used for FDM 3D printing:
Common: PLA ABS PETG Specialty: Flexible (TPU, TPE) Nylon Filled (woodfill, bronzefill, etc.) Polycarbonate Support: PVA HIPS Filaments for FDM are also amongst the cheapest materials used in the 3D printing world.

Need a quickstart in the world of 3D printing? This is the article for you. In this guide, we'll break down 3D printing for beginners and explore machines, processes, and top tips.


3D Printing for Beginners 
FDM Explained 

JGMAKER Magic, a high performance FDM 3D printer.

“3D printing” is itself a very general term. The media, especially mainstream marketing, portrays 3D printing to be a magical technology of the future capable of replicating complex objects. But that makes it hard to put a finger on what exactly 3D printing is, technically speaking. In reality, there are many different 3D printing technologies, but FDM, on which this article is focused, is the most common one.

Fused deposition modeling (FDM) is a 3D printing technology that prints parts using thermoplastic filament, which is basically a cord of material capable of being melted, selectively deposited, and cooled. Parts are built by adding up layers on top of each other.
FDM was created because its creators wanted a way to rapidly prototype parts. Even today, rapid prototype production is one of the biggest benefits of FDM and 3D printing in general. Nevertheless, 3D printing is also slowly becoming a potent manufacturing solution.
Before we proceed with the details of how FDM works, there’s one more thing worth mentioning. In case you already did some research on FDM, you may have noticed that some sources use the term “FFF”, which stands for fused filament fabrication, instead of FDM when referring to the technology. Well, that’s because FDM is a term originally trademarked by Stratasys, and the other abbreviation is more of a general one. Remember, it’s the same technology, only the names are different.


3D Printing for Beginners 

How It Works 

Anatomy of a 3D Printer

The easiest way to understand how FDM works is to first learn the parts of an FDM 3D printer. Before we talk about specific parts, though, it’s worth mentioning that conventional FDM 3D printers can perform movements in three axes, named X, Y, and Z. The X- and Y-axes are responsible for left, right, forward, and backward movements, while the Z-axis handles vertical movement.

Now, let’s look at the main components of a 3D printer:

  • Build Platform: The build platform is essentially the surface on which the parts are made. Build platforms are usually heated to help with the adhesion of a part, but more on that later.
  • Extruder(s): The extruder is the component responsible for melting and gradually depositing the filament to build the model.
    • In truth, an extruder is made of two subcomponents: The hot end and the cold end. The hot end contains a heater and a nozzle which actually deposits the molten filament, while the cold end consists of a motor, drive gears, and other small components, which push the filament into the hot end to be melted.
    • Between the hot end and the cold end lies a heatsink and fan because it’s imperative that the cold end stays cool to avoid jamming.
    • In addition to the heatsink fan, there is usually at least one other fan meant for cooling the molten filament after it exits the extruder – this is usually called the part cooling fan.
  • Print Head: The print head has one or more extruders on it, and on the top of the print head, there’s a tube which feeds the filament into the print head.
  • Control Interface: Some modern 3D printers have a touch screen which is used for controlling the 3D printer. On older printers, a simple LCD display with a physical scroll and click wheel may be present instead of a touch interface. Depending on the model, an SD card slot and a USB port might also be present.

How a 3D Printer Prints

The process starts when you send a 3D model file to the printer. Once the print job is started, the nozzle starts to heat up. When the nozzle reaches the required temperature to melt the filament, the extruder then pulls filament into the hot end in preparation for deposition.

Now, the printer is ready to start 3D printing the part. The print head lowers down to the build platform and starts depositing molten filament, which cools and hardens shortly after exiting the nozzle, thanks to the part cooling fan(s). The filament is deposited one layer at a time, and after one layer is complete, the print head moves up in the Z-axis by a tiny amount, and the process is repeated until the part is complete.

Acquiring and Designing 3D Models

Naturally, if you want to 3D print a part, you have to have a 3D model of that part. 3D models are created using 3D modeling software, usually referred to as CAD (computer aided design) software. 

Downloading Files

With so many people gaining access to 3D printers in recent years, several sites have emerged as repositories for 3D models. Here are some of the most popular ones:

This way, anyone can get their hands on a model without any modeling skills.

Preparing Models 

                                                        JGAURORA JGcreat slicing software.

3D models need to be prepared for 3D printing using a special kind of software that translates the model into machine instructions. This is done using slicing software, also referred to as slicers. 3D models are imported into a slicer, which then virtually “slices” the model into layers. The resulting files consist of G-code, which is essentially a long list of instructions followed by the 3D printer to build the model.

G-code is the “language” of 3D printers and CNC machines. These files contain important parameters required to produce a model, such as printing speed and temperature, wall thickness, infill percentage, layer height, and many others. In other words, 3D printing is impossible without G-code files!

Supports

Another of the main functions of a slicer is to generate support material. Support is needed for parts with severe overhangs. The slicer lets you choose where to put supports and how dense you want them to be. Some slicers even offer users the ability to choose different types of support structure for easier removal or stability.


3D Printing for Beginners 

Preparing the Printer

A couple of things always need to be done on a 3D printer before it’s ready to print:

  1. Loading Filament: The extruder needs to be ready to extrude filament before printing begins. The loading process begins by heating the hot end to the filament’s molten temperature (anything above 175 °C, depending on the filament), and then loading the filament into the heated extruder.
  2. Bed Leveling: In order for the printer to deposit filament and build the object successfully, the build platform must be level. Depending on the machine, leveling can be either manual or automatic. Bed leveling is very important because, if the print bed is too far away from the nozzle, the first and the most important layer won’t stick to the bed, causing the print to automatically fail.

Post-Processing

Post-processing is the final stage of production for a 3D printed part. Here are some common post-processing steps for an FDM 3D printed part (not all steps are necessarily done):

  • Support Removal: After printing, the support material is removed, if there was any. After the removal of the support material, chances are that there are marks left on the part’s surface.
  • Sanding: That’s when sanding comes in. Exposing 3D printed parts to light sandpaper makes the surface smoother.
  • Painting: Done to alter the color of the model, add details, or add protection.
  • Polishing/Smoothing: Epoxy coating is also one of the ways used for smoothing the surface of a printed part. Specific filaments like ABS have dedicated processes, such as vapor smoothing, for achieving a smooth surface finish.
  • Welding/Gluing: In case you want to print a large 3D model that does not fit in your printer’s build volume, you can print the part in two pieces and later join the two.

New Way of Building a RC Plane

08/01/2019
by JGAURORA ADMIN

The invention of flight has enabled us to explore parts of the world that were once inaccessible. Drones are a great example of the way in which technology is enhancing and improving the way in which we live. There is no doubt that these machines will become an integral part of almost every field and industry.

The way in which RC planes are designed can have a significant impact on the way it performs. The weight of a RC plane has an impact on its flight time-the heavier it is, the less time it spends in the air and the lighter it is, the longer it can spend in the air. 3D printed RC planes are lighter and they perform a lot better during flights because the planes are more responsive and agile. In the case of hard landing or crashes, the RC planes will also remain stable.

The way in which the parts are designed and made lighter is down to the availability and range of raw materials that can be used. Thanks to 3D printing, RC planes and drones can be made of very light and affordable materials.

Conjoined Twins Separated with Help of 3D Printing

07/25/2019
by JGAURORA ADMIN

Twins conjoined at the head have been successfully separated after months of planning and hours of surgery. Surgeons used 3D scanning and printing to ensure the surgery was a success. 

After months of planning and over 50 hours of surgery, doctors separated two-year-old Pakistani twins Safa and Marwa, who were born conjoined at the head. The process was aided in part by 3D printing and modeling.

Surgeons Owase Jeelani and David Dunaway of Great Ormond Street Hospital (GOSH), UK, took on the mammoth task of separating them.

Safa and Marwa are the third set of twins conjoined at the head to be operated on at GOSH. However, they were the most difficult to separate. This was partially due to a delay in finding funding which meant the twins were older than the surgeons would have liked.

However, although their age was somewhat against them, modern technology was not. Imaging, 3D modeling, and 3D printing have hugely advanced in recent years, meaning the surgeons were able to plan their surgery in much greater detail than any previous separation.

Juling Ong is a craniofacial plastic surgeon who led the modeling team for Safa and Marwa’s separation. He explained the use of cutting-edge technologies to the BBC, saying:

“These are really unique cases and it’s not something that we get taught in medical school . . . With this software, we can make a realistic computer model to look at the extraordinary anatomy of these children and plan our surgeries beforehand.”

Planning a Successful Separation with 3D Printing

Using traditional scans, Ong was able to create 3D models of the twins’ brains, skulls, and skin.

“It allows us to try out different strategies for operating, and the likely danger areas given the twins’ unique anatomical structures,” explained Ong to the BBC.

As well as being able to look at the computer models, the team also 3D printed the models so the surgeons could hold the girls’ skull in their hands and study it more closely.

GOSH’s 3D technician Kok Yean Chooi printed the skull in soft plastic. It was used to plan how to divide the layer of skin between Safa and Marwa’s shared skull. This wasn’t the only 3D print. In fact, many were created before the girls went into surgery.

The team also used virtual reality to investigate the girls’ vascular system.

“This is clearly the way of the future,” said Jeelani. “We are blessed [at GOSH] in terms of the engineers and the software specialists — the skill sets they bring to the equation are skills that we as doctors with our medical training don’t have.”

The surgery went well and the two little girls are no longer conjoined. They will spend six more months in the UK to complete a rehabilitation program before heading home with their mother, Zainab Bibi, to Pakistan.

To stay up to date with how the girls are doing, you can visit the charity website set up by surgeons Jeelani and Dunaway called Gemini Untwined.
