What is 3D Printing?

Off late 3D printing has gained ample popularity. It is used extensively in the realms of jewelry making, medicine, architecture and designing, educational and industrial processes. 3 D printing encompasses the process of creating a three dimensional structure from a digital file. This aim is achieved using additive processes. Using additive processes, an object is created by laying successive layers of material. 3D printing differs from the normal, conventional method which relies on the removal of the material by cutting and drilling.

How will 3D Printing help me plan my surgery?

As Medical science has embraced this 3D printing technology, several intricate surgical procedures have been simplified extensively. 3D printing provides a one stop, comprehensive solution, wherein the medicine practitioners can gauge the complexities of in vivo organs by studying the pre-operative models. These 3D Printed medical models bear great resemblance with real, in vivo organs, providing the surgeon the feel of the organ. This facilitates smoother surgical procedures.

What is the process of generating a Model? What are the Imaging requirements and turn around time?

Generation of a patient – specific pre- operative surgical model, surgical guide, implant, etc. is an elaborate process where keen interest is paid to the intricate details. It encompasses three major steps viz. segmentation of the desired region on the 2-D imprints of MRI,CT or Echo Scan, generation of 3D CAD model and lastly obtaining a life size print of the model. More information here. A CT/MRI scan with good resolution and contrast is preferred to segment out the most accurate details. For more information on imaging requirements, kindly Contact Us. Depending upon the complexity of models, the turn arout time can vary from just 2 days to a couple of weeks.

How do I know that the model is anatomically precise?

Our firm’s core principle is consumer satisfaction. Several parameters are so designed and adapted to ensure that the 3D printed model is anatomically precise. Our FDA approved software’s tools enable the precise generation of models. 3D printed models are channelled through a series of software-based checks and conformations which ensure that the model is of superior quality with accurate anatomically features.

Do you provide specific anatomy study models or have an off-the-shelf library where I can purchase models from for educational purposes?

One of our objectives is to generate patient specific models, especially tailor- made to meet an array of anatomical needs. Several different models, specific to certain functions, forms, fits and location, can be generated. We are constantly working on different types of cases to develop a library of these models. Kindly Contact Us for more details.

How do I choose the most suitable material for my requirement? Is the material bio compatible? Are there any side effects that I need to worry about?

A boon to the 3D printing industry has been its flexibility in terms of materials that can be explored. POP-based full-colour models, ABS and flexible plastics, acrylic and resin-based materials allow us to serve a comprehensive array of applications. Several biocompatible materials such as PLA (Poly Lactic Acid), Nylon, PEEK, Titanium, Chrome-Cobalt, etc. have enabled millions to imagine the limitless possibilities. These materials are extremely durable and inert, having no side–effects.

Anatomiz3D is working towards making the most of this flexibility. We consult on materials based on your requirement or application of the final product. More information on the types of materials and printer can be found here.

What are the costs involved?

3D printed models vary according to patient’s needs. The cost of each model depends upon the consumer’s needs and varies according to the intricacies involved, anatomy of the structure, printing time, material type and volume. We believe in providing the most comprehensive solutions at reasonable costs, thereby ensuring that maximal consumer satisfaction is achieved.

How does 3D imaging work?

The term “3D imaging” refers to techniques that allow two-dimensional (2D) imaging sensors to capture and store 3D data about the physical world around us. The EinScan-S desktop 3D scanner uses structured-light phase-shifting technology to acquire the 3D coordinates (x y z) of real-world objects. Structured-light imaging extracts the 3D surface shape based on the information received from a projected structured-light pattern. The EinScan-S proprietary structured-light algorithms feature high-speed scanning, lower noise and finer details when compared to laser scanning technology.

What is 3D scanning (sometimes referred to specifically as 3D laser scanning)?

3D scanning is the fast and accurate process of using a 3D scanner to convert physical objects into digital 3D data (in the most basic terms, it quickly and accurately gets your part into the computer). These scanners capture xyz coordinates of millions of points all over an object to recreate it digitally.

What are the benefits of 3D scanning?

3D scanning saves money and especially time at every point of the manufacturing process, anywhere from design to production.

Does the material of my part make a difference for scanning purposes?

Generally,no. Almost any material lends itself to 3D scanning. Although 3D laser scanners can have trouble with black, translucent or reflective objects (for obvious reasons), these objects can either be sprayed with a flat white talc powder or can be scanned with a different type of 3D scanner. It would be an extremely rare case if we could not scan an object because of its material.

Will 3D laser scanning damage my part in any way?

Absolutely not. The lasers used in 3D laser scanning will not damage parts, and are even safe for your eyes.

How accurate are your 3D scanners?

Our average 3D scanners are accurate to +/- 50 microns, or .002 in (two thousandths of an inch) for any point in space’s xyz coordinate. This is generally more than enough accuracy to cover the needs of almost all 3D scanning projects. If greater accuracy is required, we have options that use specialized 3D scanners which can provide finer scan data.

Can I get parametric data from a 3D scanner?

Yes. While 3D scanners do not directly output parametric data, our experienced engineers can reverse engineer fully parametric models based on the 3D scan data.

What can I 3D scan?

Generally, you can scan all visible not-too-shiny surfaces that do not move for at least a few seconds of scanning time. The 3D scanner range we offer can scan an object size of 60-500 mm, but can be adapted for scanning small objects with fine details or larger object like a car engine.

The best objects to scan with this 3D scanner are:

  • Bounded by the specified 60-500mm in any dimension
  • Opaque, not translucent/transparent
  • Not-too-shiny surfaces
  • Asymmetrical, with abundant scan alignment features
What's the best way to successfully calibrate?

Which file formats can be exported?

You can export the 3D models directly from the scanner software to all the standard formats:   .dae, .fbx, .ma, .obj, .ply, .stl, .txt, .wrl, .x3d, .x3dz, .zpr

Is there a rule of thumb when it comes down to 3D-Printing in general?

Keep the nozzle temperature as low as possible and cool as much as you can.

The above mentioned rule of thumb can be seen as the basis of 3D-Printing. This rule is created with hours of testing and experimenting with different 3D-Printer filaments and 3D-Printing techniques. Of course there are exceptions and boundaries to this rule, for instance, some filaments react badly to cooling and others cannot be printed below a certain temperature without risking under extrusion.

What is a PLA Filament?

PLA (Polylactic acid) is biodegradable thermoplastic derived mostly from corn. Due to its brittle nature, PLA is not recommended for 3D printing. Printed object may break down after a few months.

Furthermore, the material has sharp edges when it breaks, making it a hazard especially when removing the support material from printed parts.

What kind of plastic filaments can be used?

ABS, PLA, HIPS, TPU, PETG,PC, Carbon Fiber plastic materials are used on our 3D printers.

What material should I use? ABS or PLA?

Use of PLA is avoided as it has lower strength as compared to ABS when it absorbs moisture. Acrylonitrile-Butadiene-Styrene (ABS) printed parts have a strong, hard, and rigid output.

How much stuff can I print with one roll of filament?

In order to answer this, we need to consider a few things. We need to know the dimensions of the object, the percentage of infill and  the part requires support material or not.

Why won’t the plastic extrude properly?

3D printing is tricky beast, and there are many potential reasons why your extruder is having problems. The first thing to do, is to make sure that you know what material you’re using, and that you have the proper temperature settings.

Each material has an ideal range of temperatures

PLA: 190-210°C
ABS: 220 -240°C
NYLON: 240C-250°C
LAYWOOD: 175-250°C
LAYBRICK: 165-210°C
SOFT PLA/BENDLAY: 220-235°C
GLOW IN THE DARK PLA: 185-205°C
PVA: 170-190°C

How should I store my filament?
To store filament correctly so that it doesn't come into contact with moist air, you have three practical and relatively cheap options:
  1. Use double-zipped vacuum bags with a valve for sucking the air out with a standard vacuum cleaner.
  2. Store your filament spools in transparent storage boxes with sealed lids.
  3. Another great solution to creating a moisture-free environment for filament storage is a dry box. These cabinets provide the kind of low-humidity environment that is perfect for filament storage. The technology works through a electronic dehumidifier system that constantly dehumidifies the interior of the box. As a result, you’ll limit the contact that your filament has with humid air to practically nothing. For you, this means stronger, more reliable prints.
What temperature should it be to dry PLA filament?

For drying PLA filament you want to ensure more care, as 7°C will be too hot. We recommend at the very lowest temp your oven will go around 4°C. Even at this temp your PLA will soften, so drying PLA in the oven won't always give you the results you're after.

Can PLA get wet?

Some of you think that PLA will dissolve in water and/or will degrade in moist or wet environments. That is totally false. The 3D printable plastic, which is often used as a support material with dual extrusion 3D printers and which dissolves in water is PVA (Polyvinyl alcohol), not PLA.

Does PETG filament absorb moisture?

Wet PETG is significantly more brittle than dry, and the interlayer adhesion is significantly reduced. Fortunately, most of the filaments we print with aren't very susceptible to hydrolysis at room temperature without the presence of an acid or a base. Nylon and PC can absorb enough water in 48 hours to ruin prints.

What is the difference between PET and PETG?

PET, or 'polyethylene terephthalate', is a combination of two monomers. PETG is of the same chemical composition as PET but with the addition of glycol. With just this one addition, the chemical composition is completely changed, creating a whole new plastic.

What does FDM printing mean?

FDM stands for Fused Deposition Modeling, which simply means that material is deposited in single layers that fuse together to create a 3D object.

How does SLA printing work?

Stereolithography (SLA) printing was first invented in the 1980's and works by curing resin with light. The light solidifies a liquid resin via a process called photo-polymerization and builds objects layer by layer.

How does SLS print work?

Additive manufacturing, or 3D printing, is the process of turning digital designs into three-dimensional objects.During SLS, tiny particles of plastic, ceramic or glass are fused together by heat from a high-power laser to form a solid, three-dimensional object.

What is the difference between SLA and SLS?

There are some common denominators, for example, both use a laser to trace out and build individual layers. For SLA a liquid resin is cured, where as in SLS powder is selectively fused together.

Why is sintering done?

Because the sintering temperature does not have to reach the melting point of the material, sintering is often chosen as the shaping process for materials with extremely high melting points such as tungsten and molybdenum. The study of sintering in metallurgy powder-related processes is known as powder metallurgy.

How does direct metal laser sintering work?

To create your 3D print, a laser in the printer melts the powder together. So here's how it works: A super-thin layer of Aluminum or Titanium powder is spread out by a roller. The print chamber of the 3D printer is then heated up.

What is powder bed fusion?

The Powder Bed Fusion process includes the following commonly used printing techniques: Direct metal laser sintering (DMLS), Electron beam melting (EBM), Selective heat sintering (SHS), Selective laser melting (SLM) and Selective laser sintering (SLS).

What is MJP technology?

MJP or MultiJet Printing is an inkjet printing process that uses piezo printhead technology to deposit either photocurable plastic resin or casting wax materials layer by layer. MJP is used to build parts, patterns and molds with fine feature detail to address a wide range of applications.

What is PolyJet material?

PolyJet is a powerful 3D printing technology that produces smooth, accurate parts, prototypes and tooling. With microscopic layer resolution and accuracy down to 0.1 mm, it can produce thin walls and complex geometries using the widest range of materials available with any technology.

What are the inputs we need to give for 3D designing?

The inputs that you can give are rough ideas scribbled on a paper, any physical component, reference models of components, and images.

When I upload a 3D model to the site, textures and colours are sometimes missing: how can I make them appear?

When you upload your 3D file in certain formats, for instance .obj, you should include colours, textures and the 3D model in a .zip archive. To upload your 3D model to the site, you can send the  texture files like .VRML, .ZBD, .FBX files by .zipping from your computer.

Why do some designs require fixing before they can be made?

When you upload a design to our gallery, you may find that some geometric issues prevent it from being built without modifications. The most common reason is that the design does not unambiguously represent a solid object. Another possibility is that some parts are too thin to be synthesized.

Many 3D software modelling tools currently available focus on creating models for rendering and animation. Most of the time, this type of software does not require the object to be solid and only represents its surface. This information is sometimes insufficient to reconstruct a solid object solely based on the 3D design.

If possible, our software tools will attempt to automatically fix the design. However, some issues require manual editing by the designer.

What is the advantage of CAD?
  • One of the Benefits of CAD is to Draw to Scale.
  • The ability to producing very accurate designs.
  • Drawings can be created in 2D or 3D and rotated.
  • Other computer programs can be linked to the design software.
What is the purpose of reverse engineering?

Reverse engineering is taking apart an object to see how it works in order to duplicate or enhance the object. The practice, taken from older industries, is now frequently used on computer hardware and software.

ND is used for boring and where high energy but low repetition are required. The ND-YAG laser is used where very high power is needed and for boring and engraving. Both CO2 and ND/ ND-YAG lasers can be used for welding.

How does a vacuum casting machine work?

A vacuum casting machine uses a vacuum to suck the molten metal into the mold. A force is needed to overcome the surface tension of the molten metal. The centrifugal machine must be securely bolted to a level surface with a protective fence around it. A metal washtub or a drum from a clothes dryer can be used.

What are the advantages of casting?

The advantages offered by plaster casting include: A very smooth surface finish. The ability to cast complex shapes with thin walls. The capacity for forming large parts with less expense than other processes, such as investment casting.

Why choose vacuum casting?

Vacuum casting or vacuum duplication involves injecting a resin into a silicone mould. Because of its cost and deadline, this method is most suited to pre-series, with a faithful reproduction of the original model and a result close to the end result in the “right material”. Vacuum casting technology is recommended for the production of around ten to one hundred parts for mechanical or visual tests.

In a CNC part program, using G and M code Language describes the sequence of operations that the machine must perform in order to manufacture a component.

Codes that begin with G are called preparatory words because they prepare the machine for a certain type of motion.

Codes that begin with M are called miscellaneous words that control machine auxiliary options.

How does CNC Routing work?

As with other CNC machining, CNC routing uses a computer-controlled system to drive the mechanical operation of the process. The main components of a CNC router process include:

  • CAD model drawing that is transferred into a CNC-readable program, known as G-code. The G-code is used to setup the CNC routing machine.
  • CNC controller and computer system that works to direct the movement and follow the CAD model design.
  • The spindle is the CNC routing cutter and it rotates removes pieces of material at a different speed and material softness.
  • A cutting bed supports and secures the material. The bed often has a vacuum motor to ensure stability to achieve the intricacies of the finished part or product.
How does simple compressed air affect the laser cutting process?

In combination with the laser technology, it fulfils several important functions at the same time during the laser cutting procedure. The targeted air flow drives the material melt out of the cutting gap. Compressed air flow cools the heat influence zone at the focal spot. Protects the optical lens from soiling.

Can laser cutters cut at an angle?

CO2 laser cutting technology is configured to meet the material surface at a 90 degree angle. For example, the material can be cut at an angle of 45 degrees with the tool positioned at a slant, which means a wedge can be cut out.

How does laser cutting work?

When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate.

What materials can be cut with laser?
Materials we can laser cut
  • ABS (acrylonitrile butadiene styrene)
  • Acrylic (also known as Plexiglas, Lucite, PMMA)
  • Delrin (POM, acetal) – for a supplier, try McMaster-Carr.
  • High density polyethylene (HDPE) – melts badly.
  • Kapton tape (Polyimide)
  • Mylar (polyester)
  • Nylon – melts badly.
  • PETG (polyethylene terephthalate glycol)
What is Ultimaker Cura?

Cura is an open source 3D printer slicing application. Ultimaker Cura is used by over one million users worldwide and it is the preferred 3D printing software for Ultimaker 3D printers, but it can be used with other printers as well.

How does 3d printing work?

Although there are several things to keep in mind while 3D printing, the steps it takes to create a 3D print are pretty easy. Basically, this is the process for 3D printing on an Ultimaker:

  1. Download or design a 3D model
  2. Convert the 3D model to a 3D print file with the software Cura
  3. Start the 3D print on the Ultimaker
Can I 3D print everything with Ultimaker?

With an Ultimaker you can 3D print a lot of things, but as every technique has its limitations, not everything is possible. The Ultimaker uses the 3D printing technique FFF (Fused Filament Fabrication), with which layers of melted plastic are placed on top of each other. With this technique very complex structures or “overhanging” parts could be hard to print.

What materials can be used for 3D Printing with Ultimaker?

Ultimaker printers use PLA and ABS as materials for 3D printing. We usually recommend to use PLA (especially if you’re new into 3D printing), as this is the easiest material to print with due to its technical properties. For printing with a material like ABS a heated bed is recommended, since ABS has the tendency to warp when it cools down fast.

Because of the open filament system on an Ultimaker you are also free to try other materials (e.g. lay wood or nylon). You only need to be aware that we can’t fully guarantee the quality of materials not supplied by ourselves.

How to load the filament in Ultimaker printers?

Before the filament can be loaded, the filament spool needs to be placed on the spool holder. Once you’ve done this, you can insert the filament into the feeder and guide it through the bowden tube into the hot end.

For detailed instructions on how to insert filament into your Ultimaker, you can take a look at the manual of your 3D printer.

If you experience difficulties when loading the filament, please take a look at Ultimaker troubleshooting guides.

If I have a STL or OBJ file, am I good to go with my Ultimaker?

When you create CAD models yourself, or when you download them from sites like YouMagine.com or Thingiverse.com, your 3D model file will be in the form of STL, OBJ, or another CAD file. Your printer can’t read this type of file directly.

If you put an STL or OBJ file onto an SD card and then insert that card into your Ultimaker, that file will not even appear on the file list on the printer’s digital readout.

In order to print such a CAD model, you must first convert it into G-code, which is a list of machine instructions that your printer can read. To convert CAD models into G-code, you need to use a slicing program like Ultimaker Cura software. The slicer breaks your CAD model into layers and lines that your printer can understand.

How do you start a print in Ultimaker 3?

To print a model through the Ultimaker App, follow these steps:

  1. Connect to your Ultimaker 3 by selecting the model from the list of discovered printers, or manually add a printer with the IP address.
  2. Select "Start a new print".
  3. Load a 3D model from your device, or print the Ultimaker Robot.

What shall I do if the object can't stick to the Build Plate?

If the first layer cannot stick to the build plate, the model will definitely fail later on. As the foundation of the model, the first layer is quite important for the success of the print job.

Reason 1: The first layer of your model is too thin.

Solution: Change the value of “First Layer Height”, and it should not be less than 0.2mm.

Reason 2: The build plate has not been leveled.

Each Flashforge printer has an adjustable build plate with three knobs underneath that control the distance between the build plate and nozzle. If the build plate has not been leveled, the first layer will probably cannot stick to the build plate. If the build plate is not leveled, one side may be too close to the nozzle, while the other side is too far away from the nozzle.

Solution: You need to re-level the build plate according to the correct hints. Make sure the build plate has been leveled before starting a print job.

Reason 3: The distance between the nozzle and the build plate is too huge.

Solution: Adjust the knobs under the build plate to make your extruder have a perfect distance away from the build plate — not too far and not too close. For good adhesion to the build plate, you can adjust the distance when the printer is printing the first layer.

What is the environment required for a Flashforge 3D Printer?
