Xometry's High Quality 3D Printing Services

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is a powerful 3D printing technology that produces highly accurate and durable parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping.

An additive manufacturing layer technology, SLS involves the use of a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic powders into a mass that has a desired three-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.

Stereolithography (SLA)

Stereolithography (SLA) is a robust 3D printing technology that produces extremely accurate and high-resolution parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping.

SLA is an additive manufacturing process that focuses an ultraviolet (UV) light on a vat of photopolymer resin. It offers higher resolution printing than many other 3D printing technologies, allowing customers to print parts with fine details and surface finishes. SLA 3D printing is a highly-versatile platform for making custom parts in prototype and production settings; often acting as a stand-in for injection-molded plastic parts.

Xometry offers both standard and high-resolution options for fine detail parts, and can also print larger sized parts and products, with some materials offering up to a 58" inch build area. In addition, Xometry's manufacturing partner network allows us to offer a larger variety of materials than other 3D printing companies - we offer a wide range of both Accura and Somos brand materials.

Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM) is a 3D printing technology widely known for its speed, accuracy, and competitive cost. A machine precisely extrudes melted plastic filament to create a part. Parts are very rigid, especially compared to Selective Laser Sintering (SLS), which makes them a great fit for projects with a rigidity requirement. Xometry's FDM solution offers large build volumes up to 24″ x 36″ x 36″, a variety of colors, and a diverse selection of production-grade thermoplastics — from ABS to Polycarbonate to Ultem.

HP Multi Jet Fusion (HP MJF)

HP Multi Jet Fusion is a new 3D printing technology that produces highly accurate and durable parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping. Since the process uses well-established 2D printing ink-jetting, it has remarkably fast layer times compared to other powder bed fusion technologies.

PolyJet 3D (PJ3D)

PolyJet 3D is a 3D printing technology known for its customizable material properties and excellent surface finish. It works by jetting UV curable resin onto a build tray in a process that is somewhat similar to inkjet printing. PolyJet 3D printing offers one of the most advanced industrial 3D printing solutions available, producing parts with incredible precision and speed. It also supports a wide variety of build materials including rigid and rubber-like plastics. Xometry's PolyJet solution has a maximum build envelope of 19. 3 × 15.4 × 7.9 in. (490 × 390 × 200 mm) in a variety of colors and materials.

Direct Metal Laser Sintering (DMLS)

Direct Metal Laser Sintering (DMLS) is an 3D metal printing technology that builds prototype and production metal parts from a CAD file using a laser to selectively fuse a fine metal powder in either stainless steel or aluminum materials. A DMLS machine is capable of producing highly complex features and all-in-one assemblies using metal materials that would be difficult to achieve with subtractive manufacturing techniques.

Our DMLS metal 3D printing service typically offers build volumes up to 250 x 250 x 325 mm, but we may be able to accommodate larger part volumes upon request in the quote. (See our Manufacturing Standards for more details) A good first step is to find out the cost of the parts you need using DMLS and compare them to other 3D printing processes and CNC machining.

Download the DMLS Design Guide.

Carbon DLS™

Carbon DLS™ uses digital light projection, oxygen-permeable optics, and programmable liquid resins to produce products with end-use durability, resolution and surface finish. This 3D printing technology is called Digital Light Synthesis™, or DLS for short. Another legacy term for the process is Continuous Liquid Interface Production (CLIP). Along with Carbon’s custom liquid resins, DLS unlocks new business opportunities and product designs previously impossible, including mass customization and on-demand inventory of end-use products.

Carbon bridges, and sometimes substitutes, for processes like Urethane Casting and Injection Molding service production, because the materials are urethane-based or epoxy-based, giving excellent mechanical properties. There are even elastomer and silicone resins that outperform most additive manufactured rubber-like materials.

The typical build area is 7.4” x 4.6” x 12.8”. Parts with dimensions exceeding 4” x 4” x 6” will require manual review.

Download the Carbon DLS Design Guide.

Metal Binder Jetting

With binder jetting, an inkjet print head quickly deposits a bonding agent onto a thin layer of powdered particles -- either metal, sand, ceramics or composites. This process is repeated, layer-by-layer, using a map from a digital design file, until the object is complete. Binder jetting is offered through our Digital RFQ Marketplace through Xometry's partnership with ExOne.

Follow this link to read more about our quality assurance measures.

How do I select the right 3D printing process for my prints?

You can select the right 3D printing process by examining which materials suit your need and what your use case is.

By material: if you already know which material you would like to use, selecting a 3D printing process is relatively easy, as many materials are technology specific.
By use case: once you know whether you need a functional or visual part, choosing a process is easy.

For more help, read our guide to selecting the right 3D printing process. Find out more about Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), Multi Jet Fusion (MJF) and Stereolithography (SLA).

How can I reduce the cost of my 3D prints?

In order to reduce the cost of your 3D prints you need to understand the impact certain factors have on cost. The main cost influencing factors are the material type, individual part volume, printing technology and post-processing requirements.

Once these have been decided, an easy way to further cut costs is to reduce the amount of material used. This can be done by decreasing the size of your model, hollowing it out, and eliminating the need for support structures.

3D printers in military service - big overview

Overview: 3D printers in military service.

Source: https://all3dp.com/

The military industry has always been at the forefront of progress: many inventions either began their life as military or dual-use products, or, in the very first years after their appearance, were involved in this area . In this age of digital technology, this fate has not escaped 3D printing.

3D printers are actively used by military contractors and direct employees of all branches of the military.
In this article, we will talk about the use of 3D printing in the military-industrial complex around the world: from providing military equipment with spare parts, to operational printing of drones and buildings anywhere in the world.

In Russia,

JSC "Federal Research and Production Center "Titan-Barricades", which develops missile systems and military vehicles, has bought and uses in prototyping a kit based on an XJRP SPS450B 3D printer. The kit consists of two devices: directly a 3D printer with a large print area, working on SLA technology, and a polymer curing chamber.

The 3D printer is planned to be used to create miniatures of future parts, cases or mechanism assemblies. The first product made on this 3D printer was a prototype wheel with a tread.

Ilyushin specialists plan to produce some simple parts for the Il-112V military transport aircraft using 3D printing.

Together with specialists from the Voronezh Aircraft Plant (VASO), PJSC Il specialists use 3D-printed parts as test samples, which will be replaced with originals made by the classical method before departure. But in the future, it is planned to master the printing of simple components that will be installed on mass-produced aircraft.

Pavel Chernikov, First Deputy General Director of PJSC Il, said: “The IL-112V is being created from scratch, and many parts and components need to be improved during installation on the aircraft. We started using a 3D printer to see how right or wrong our calculations were. Such technologies make it possible not to interrupt the finalization of finished products, which, in turn, significantly reduces the installation time of equipment and reduces the cost of the production process.”

Research and Production Corporation "Uralvagonzavod" named after F. E. Dzerzhinsky purchased a 3D printer S-Max manufactured by ExOne.

This printer is designed for making sand molds. Molds are used for casting metal blanks. As the deputy chief metallurgist of NPK Uralvagonzavod said: “We will no longer have to manufacture expensive foundry equipment for experimental, new products and complex castings of small series. It will be enough for a designer to develop a 3D model of the required casting, according to which, also in 3D, the mold is made. The finished cores will go to the foundry. In addition, they can be transported to solve the problems of the corporation over any distance."

This is not the first professional 3D printing system that Uralvagonzavod uses. In 2015, the company purchased a Fortus 400mc 3D printer manufactured by Stratasys Corporation. This printer is used in the production of parts for the T-14 "Armata" tank and other vehicles manufactured by Uralvagonzavod.

Representatives of the enterprise note that the introduction of 3D printing saves time and production resources. It is not required to spend forces on turning metal samples. If a part doesn't fit, it's easier to reprint it than remake it.

Russian Helicopters Holding, according to its CEO Andrey Boginsky, plans to 3D print about a hundred parts for rotorcraft by 2020.

In 2018-2019, it is planned to conduct a series of bench tests in order to obtain all the necessary certificates for printed parts by mid-2020. In total, it is planned to test about a hundred parts and assemblies.

Compared to traditional parts, 3D-printed parts are lighter and their production will be deployed at the Kazan Helicopter Plant. As a result of the use of parts obtained by 3D printing, the holding plans to reduce the cost of products.

In the world

The road of army 3D printing is not paved with roses. When we hear about cool 3D printed military projects, we have to consider some of the challenges that come with doing them.

Quality certification problem. Many things that the army is supposed to produce using 3D printing are designed for harsh operating conditions, they are subject to high requirements for compliance with dimensions, geometry and quality, and an unsuccessfully printed part can lead not only to monetary losses, but also to the death of soldiers . This issue will most likely be resolved by certification of the 3D printers themselves.

Insufficient printing speed for the army. Even the most expensive 3D printer is not fast enough. There are also issues of privacy/security, copyright, and many other little things that are not obvious at first glance.

While these issues are being addressed, the US Department of the Navy has decided to host a 3D printing hackathon. 12 organizations were invited to participate, which showed their developments in the field of 3D printing for the Navy. According to the participants, fully or partially printed inventions: “Allow to improve the ability to maintain combat readiness.”

One of the new and memorable developments was the four-legged transporter robot (MeRlin). It turned out to be quite compact and can run, jump and walk up and down stairs. Three-dimensional printing made it possible to create, right in the supporting frame of the robot, a hydraulic manifold that serves to transfer energy to the robot drives. Those interested in robotics will find Merlin similar to the transport robots of Boston Dynamics.

Aviation

A 3D-printed drone was launched from one of the British Royal Navy ships at sea, HMS Mersey. The device was created in collaboration with the University of Southampton.

Body made of nylon, laser sintered. With a wingspan of one and a half meters, the drone weighs only three kilograms. The main task of this project was to create a small drone for exploring the surroundings, which can be quickly printed on board the ship.

The drone, named SULSA, was equipped with a small video camera. Management was carried out by researchers from Southampton using video cameras. The flight, with a range of 500 meters, lasted only a few minutes, but proved that 3D printed drones could be launched from the sea.

3D printing solves the problem of ship capacity by allowing equipment to be printed at sea as needed. The only thing you need to have on board to print a drone is a 3D printer and a supply of nylon, which is disproportionately cheaper than a case made using traditional technologies, and takes up much less space.

The only drawback is the print speed, but it is expected to improve in the near future. Engineers from the American Army Research Laboratory (ARL) are trying to fight this shortcoming. They are developing drones that can be made within a day. Engineers are building drones that can be used to assist soldiers in communication, delivery, and aerial surveillance.

Drones are made using off-the-shelf motors and propellers, but their body is almost entirely 3D printed. The maximum speed of the drone is 55 miles per hour. Drones can either be controlled by the operator from the remote control or operate in a completely autonomous mode. Work continues to reduce noise and increase flight range, maneuverability and payload.

The US Army is partnering with the Marine Corps to develop an unmanned vehicle parts catalog that can be downloaded to an employee's tablet. The software of this catalog allows you to order or 3D print a product directly from it.

In addition to experiments with drones, 3D printing is also used in “big” aviation.

For example, the US Air Force has announced that it will 3D print toilet seats for military transport aircraft. The announcement comes after a scandal erupted when it was reported that each toilet seat cost the Air Force $10,000 to replace.

The public, which already believed that the government did not always save on military spending, was extremely outraged. After an investigation initiated by one of the senators, the military department announced that it would print toilet seats on 3D printers.

Why is the toilet lid so expensive? These covers were mass-produced by Lockheed Martin, and in 2001 this giant of the military industry stopped their production. In addition, the military department explained that the C-5 toilet seat is not only a cover, but also part of the lavatory wall, which is designed to protect the body of the aircraft from corrosion that can be caused by urine.

According to the manufacturer, its high cost is due to the need to suspend the production of other goods. In the case of independent production of the Air Force, the spare part will cost only $300.

The manufacturer now claims that the US Air Force does not own the copyright to this cap. It is not known how this lawsuit will end, but the Air Force says that they will no longer buy this spare part, because they can make it themselves much cheaper.

As stated by the department: “The use of 3D printing allows us to create parts that are no longer being produced, resulting in significant cost savings.

Another example of 3D printing was demonstrated by the Maryland Marines. Using 3D modeling and 3D printing, they made a $70,000 F-35 fighter jet part for just 9 cents. The Marines were assisted by Sam Pratt, a mechanical engineer in the design office of the Carderock Additive Technology Factory.

Sam revealed that he was with a support platoon in South Korea teaching CLB-31 Marines how to design 3D models and how to use 3D printing. His main task was to test the performance of 3D printers on marine vessels. He also taught employees how to use Solidworks CAD.

When there was a problem printing a part needed to repair an F-35, a Marine officer offered to team up to cooperate. It turned out that the employees had already developed this part, but could not find the right dimensions. The fact is that they used a hobby-grade 3D printer and the free 3D editor Blender - Blender is ideal for implementing art projects, but it is difficult to create engineering products in it.

Pratt helped with modeling and printing issues, the part was printed in PET-G.

Currently there are about 90 parts for ground vehicles that are approved for 3D printing in the military, you can download one of these parts and print it.

Large manufacturers are also moving forward and mastering 3D printing technologies. Thus, the giant of the aviation and military industry Lockheed Martin is actively investing in 3D printing.

Lockheed Martin uses 3D printing in its manufacturing processes, with over a hundred 3D printers in its arsenal for prototyping, tooling and printing finished products.

There are several reasons why Lockheed Martin uses 3D printing:

  • Reducing the time of production of products - up to 80%;
  • Reducing the weight of parts - up to 40%;
  • Proven reliability of parts in difficult conditions;
  • The most important thing is the possibility of an additional increase in production in the near future.

For example, it takes 18 to 20 months to manufacture fuel tanks for spacecraft using traditional technologies. The production of such a tank by 3D printing takes two weeks. In this case, a better uniformity of the structure of the tank elements is achieved. The tanks are manufactured using a Sciaky printer using EBAM (Electron Beam Direct Manufacturing) technology, in which a bar of metal material is heated by an electron beam.

Lockheed Martin's 3D printed products have already passed the lab testing stage and are in active use. Some of them travel around our solar system: the Jupiter-exploring Juno satellite has eight 3D-printed brackets, and the Orion spacecraft uses printed high-pressure valves.

Fleet

South Korea is 3D printing loudspeaker grilles for aircraft carriers. Shipping these gratings from Europe took up to seven months and cost $612 each. The printed part is made in 4-5 hours and costs about $35. Printing parts reduces their cost and production time, and localization of production reduces dependence on foreign supplies, which may be delayed or become unavailable for various reasons.

General Electric has contracted with the US Navy to develop software for rapid 3D printing of spare parts for ships, aircraft and other critical military installations. The contract, worth nine billion dollars, is designed for four years and provides for the creation of technology "digital duplicates" - a complex of software, base models and hardware. This technology will be used both for those spare parts that are no longer manufactured, and for new parts of ships and aircraft.

The project is being implemented in two stages: at the first stage, software and hardware parts will be developed, at the second stage they will be combined into a complex capable of quickly creating the necessary products using laser metal melting technology (DMLM).

Ammunition and small arms

The US Army has designed and 3D printed a fully functional grenade launcher called "R.A.M.B.O". The development of the grenade launcher took about six months. He fires 3D printed grenades

The development of small arms began in the private sector, with the most primitive pistols. On the Internet, you can find drawings of products such as the sensational Liberator. The first 3D printed pistol was printed on a professional Stratasys Dimension SST printer. The gun is chambered for 9 caliber rounds.mm and is charged during assembly.

The very possibility of obtaining weapons using 3D printing so excited the public that the drawings of the "Liberator" were withdrawn from public access, and the United States introduced a ban on 3D-printed weapons.

Solid Concepts has created a replica of the .45 Browning M1911 pistol, the Solid Concepts 1911 DMLS, using selective metal laser sintering. The first sample withstood 50 shots, later ones are capable of firing 600 shots without visible damage.

Recently, the ban on the distribution of 3D printed weapons was lifted by a court decision. So, it is now possible to print weapons in the USA, with some restrictions: they can be no more than 50 mm in caliber and models cannot be freely available. This ban was easily circumvented by Defense Distributed, which posted models of their rifle for sale on one of the online services.

The helmets are made of PVC and bear the coat of arms of Pope Julius II, who founded the Swiss Guard in 1506.

The US military turned to the creators of the Iron Man costume, a movie character, for help in creating uniforms for the soldier of the future. The military commissioned Legacy Effects to develop and print the prototype components for the TALOS Special Outfit Kit.

TALOS will contain a cooling system to maintain a comfortable temperature in the suit, a tactical display and an integrated exoskeleton.

Building

The US Army Research Engineering Team printed a large building in just 21 hours. The area of ​​the building is 47.5 square meters. The barrack-style building is the result of a three-year US Army Construction Engineering Research (ACES) program with a laboratory in Champagne, Illinois.

The building looks like an ordinary house, but in the future such buildings can be given any look. Such buildings are also more energy efficient than traditional ones - they require less energy for heating and cooling.

ACES cuts the amount of building materials used in half. Reducing the need for labor is 62%, compared with the construction of plywood structures.

ACES allows buildings to be printed using local materials.

Self-Sufficiency

A collaboration between the US Army Research Laboratory and the Marine Corps has led to the development of a technology to produce 3D printed PET filament from plastic waste such as water bottles.

According to the military, water bottles and plastic packaging are the most common litter on the battlefield. Both US and allied forces produce large amounts of this waste, and the ability to recycle it will reduce the cost of transporting raw materials. The filament obtained from recycled materials, provided that it is properly cleaned and dried, is completely equivalent in tensile strength to its analogue from primary raw materials.

A plant is being developed, housed in a standard shipping container, that will allow the production of filament from waste.

The US Army is also developing food printers. Their advantages are obvious:

  • the possibility of reducing the cost of food, compared with the traditional delivery of rations from abroad;
  • the possibility of compiling an individual menu, in accordance with the preferences of each soldier;
  • the possibility of individual balancing of the diet, depending on the dietary needs of each soldier.

The printer, like classic 3D printers, stacks components in layers.

The development was sponsored by Raytheon, one of the defense industry companies.

According to the developers: “The use of this technology makes it possible to obtain cheaper and more versatile systems than those obtained by classical methods. This technology has obvious advantages in the military sphere, but it can also be used in civilian industry, for example, in the production of weather stations or unmanned vehicles. The main problem was obtaining ink with desired properties, capable of working with high-frequency radiation.”

The 3D printer is equipped with two heads with different operating principles. One applies the ink by spraying, the second fixes them by microvibration. Radar system components such as a voltage controlled capacitor (varicap), phase shifter (for electronic control of phase array radar systems) and frequency filters can be manufactured using this technology.

The ink material is based on nanoparticles that can be injected into molten plastic and then solidify with it, creating conductive structures.

The US Air Force Research Laboratory teamed up with American Semiconductor to create a silicon-polymer memory chip.

Using 3D printing technology, they have developed a new ultra-flexible chip with built-in sensors.

According to American Semiconductor, the thickness of the silicon wafer is 2000 angstroms. This tiny chip can measure humidity levels, temperature, muscle fatigue, and so on. This makes it ideal for use in new technologies for monitoring the well-being of wounded soldiers or the elderly.

Flexible electronics technology is being developed not only by research laboratories, but also by industry giants.

Apple, Boeing and the Massachusetts Institute of Technology formed an alliance to collaborate with the US Department of Defense in the field of flexible electronics.

The goal of the alliance is to have high quality flexible electronics by 2020.

The Department of Defense plans to provide a consortium called the FlexTech Alliance with $75 million over 5 years and raise $96 million in additional funding.

The consortium includes 96 companies, 11 specialized laboratories, 42 universities and 14 state and regional organizations. The key partners of the consortium are Apple, Boeing, General Electric, General Motors, Lockheed Martin, Motorola Mobility, Qualcomm and many others. Partner universities include Cornell, Harvard, Stanford, New York University and the Massachusetts Institute of Technology.

Practical applications will be primarily focused on military targets, such as uniforms with vital sign monitors. Pressure sensors can also be installed on vehicles to monitor deformation in key areas.

The civilian application of such microcircuits will help athletes control body function and improve performance, and people suffering from cardiovascular disease, control and prevent seizures. This technology will allow hospitals to monitor their patients en masse.

Possibly inspired by the computer game Quake, he created this weapon using CAD, a 3D printer and an Arduino platform. The railgun can use aluminum or graphite bullets as ammunition, firing them at a speed of 250 m/s. The design is based on six huge capacitors, which, with a total weight of about nine kilograms, store more than 1800 joules of energy for each shot. The railgun also consists of batteries, two parallel contact rails and a pneumatic ammunition supply system.

Conclusion

3D printing technology is increasingly used in the military. The main role in its promotion is played by the need to reduce costs. On-site 3D printing of parts helps to solve the problems of logistics and supply, allowing you to save time and money on delivery, which is important for the army and aviation, and even more so for the navy - it is impossible to foresee ashore and take with you everything that you might need, and delivery boarding at sea is expensive.

We have cited only a small part of the military cases as examples - it is impossible to describe in one article all the prospects for the use of 3D printing in the military industry. And most of the solutions used by the military in production are also relevant for the civilian sector.

Requirements for 3D models for 3D printing and CNC processing

  • The process of creating a product.
  • Requirements for models for 3D printing and CNC processing.
  • Fixing non-critical bugs with NetFabb.
  • Fixing non-critical bugs with MeshMixer.
  • Fixing non-critical bugs with Materialize Magic.
  • Examples of the most common errors.
  • Introduction.

    In this article, we will talk about the basic and general parameters that a model must meet in order to obtain high-quality 3D printed products. Let's discuss common errors that occur in the process of creating three-dimensional models in terms of a high-quality polygonal mesh and how to quickly fix them. Requirements for 3D models and quality issues in terms of the accuracy of manufactured parts are described in another article: The actual size of the product after 3D printing.


    The process of creating a product.

    Structure of the additive manufacturing process for the production of products:

    Designer / 3Dartist 3D printing service Discussed errors
    1. Creation of 3D model
    2. Export/convert 3D model to required format 3. Model validation 4. Compliance/failure with minimum allowable thicknesses.
    6. Preparation of control program for 3D printer (GCode) 5. Compliance / non-compliance with the requirements for the polygonal mesh of the 3D model.
    7. 3D printing process.
    9. Quality control. 8. Post-processing process.

    In accordance with the presented algorithm, at the first stage of product creation, a 3D model is developed using modeling programs in accordance with the terms of reference and standards requirements. After that, it is necessary to export the data of the simulation result program file to a format accepted by the program of the additive manufacturing control machine (for example, “STL”). The modeling process can now be done not only in solid format, but also immediately in STL. Before the next stage, possible defects in the model are identified. A model intended for 3D printing must be hermetic, monolithic and not contain cavities and gaps in the walls, which is ensured using special programs. Next, the information from the STL file is converted into commands, following which the 3D printer produces a product, this is the so-called GCode.

    During this procedure, you should select the desired scale of the part, the correct position in space, and accurately position the model on the work surface. The result of the whole process, strength, surface roughness of the part and material consumption depend on this . After the settings are made, the model is divided into layers of material, which are “fitted” into the body of the part in one working cycle of the additive machine. This process is called slicing. Slicing is done using the software supplied with the machine, or using special tools (Simplify, Skein-forge, Slic3r, KISSlicer, MakerWare, etc. ). The G-code obtained in the previous step is transferred to the 3D printer via flash memory or via a USB cable. In the process of preparing and setting up the additive machine, calibration, preheating of the working bodies, selection of the model material and setting the parameters of the equipment operation modes that depend on it are performed. On professional level devices, this step can be combined with the slicing process procedures. After all the preparatory operations are completed, the printing process starts, that is, the layer-by-layer combination of materials. Its duration depends on the type of technology and the selected parameters for the accuracy and quality of the part.

    Requirements for models for 3D printing and CNC processing.

    • List of file formats by 3D technologies.
    1. FDM (ABS, PLA, FLEX, HIPS, etc.): .STL .OBJ
    2. SLS (polyamide): .STL .OBJ
    3. SLA, DLP (photopolymer): . STL .OBJ
    4. SLM (metal): .STL+STP(STEP) .OBJ+STP(STEP)
    5. Multicolour plaster: .OBJ+texture .WRL+texture
    • Polygon mesh.
    1. The mesh must be uniform and closed. A model consisting of several polygonal meshes is not allowed! Intersection of polygonal meshes is not allowed! Holes in the grid are not allowed!
    2. Multiple models in one file are not allowed. Each object needs to be saved as a separate file.
    3. The number of polygons must not exceed 500,000.
    4. Wall thickness must be at least the specified values ​​for each technology.
    5. Inverted normals are not allowed! The outer normal should face outward. This problem is especially common when mirroring the model in some 3D modeling programs.
    6. The dimensions of the model must correspond to the dimensions of the real object.

    In 95% of cases, file errors are not critical and can be easily corrected using specialized programs that can be easily found on the Internet. Even if you are sure that everything is in order with the model, it does not hurt to check it once again for correctness.

    NETFABB - as a solution to most file errors.

    MESHMIXER is a powerful and convenient alternative.

    • Wall thickness analysis of the model.

    It should be understood that there are several 3D printing technologies. They differ not only in the materials used, but also in the accuracy of the equipment. Different equipment has its own resolution. Therefore, before sending the file for printing, it is necessary to make sure the quality of the model in terms of the specified thicknesses in the walls, rods, mesh ceilings. Detailed article about checking models for thickness.

    Fixing non-critical bugs with NetFabb.

    NETFABB (download for PC or download for Mac) is a program that allows you to solve almost any issue related to 3D printing. Let's go through the main functions of this software, which AutoDesk itself bought at one time.

    The program shows the outer part of the polygon in green, its inner normal in red. Ideally, the model should be all green. If you observe red spots, then these are polygons that are turned outward. If the entire model is highlighted in red, then the entire mesh is turned inside out.

    Even if the model is green, but there are errors in your file, the program will display a big exclamation mark in the lower right corner of the screen, and will also not be able to calculate the volume of your model.

    To treat the model, click on the red cross on the toolbar at the top of the screen. The program will put you into the treatment mode, and will indicate in yellow the breaks in the polygonal mesh, if any.

    This program has functions for removing or adding polygons, changing sizes or proportions. (I will leave these functions for independent study). I recommend that you study the entire toolbar in order to easily understand how, where and which polygons we can select and what we can change.

    To invert normals, select the polygons that look “in the wrong direction” and click on the “invert normals” button. Then click on the “Apply Repair” button.

    If your model was initially all green or inverting the normals didn't remove the exclamation mark, and the volume has not yet been calculated, you need to apply automatic treatment. To do this, go back to the treatment mode by clicking on the red plus. In the treatment mode, select "Automatic treatment", then select "Default Repair" and click "Extrude".

    The program has now done its best to repair the model automatically. Click "Apply Repair".

    Typically, these steps should have fixed your model. If after the performed operations an exclamation mark is on and there is still no volume, then you are among those 5% when the model has critical errors and errors are laid down at the modeling stage.

    Fixing non-critical bugs with MeshMixer.

    Autodesk MeshMixer is a free software for working with 3D mesh models. You can download the program from the link. The program does not have tools for creating 3D models, but a wide range of tools for modifying them and preparing them for 3D printing. The main difference between this software and NETFABB is that MESHMIXER officially supports the latest versions of macOS. For me, this is a decisive factor, because I always carry a MacBook with me, and a Windows computer is only in the office. In turn, NetFabb stopped supporting software for macOS.

    As in the case of Netfabb, you need to drop the model in STL format into the MeshMixer program window.

    At first glance, the model looks good, but let's try to test it for suitability for 3D printing (mesh requirements). To do this, you need to analyze the model for errors. To do this, go to the “Analisis” section, then click on the “Inspector” button.

    On the screen, we see how the program has highlighted areas on the model with bright colors that do not meet the requirements, which means they have errors.

    In order to fix (cure) these errors, click on the “Auto Repair All” button. The program will try to remove errors automatically. Checking before 3D printing is a must. Even if outwardly the model seems suitable to you, it is still worth checking. In the picture below, you can see the errors that are inside the mesh, although everything looks good with the model.

    However, this treatment does not always help. For example, if the model has a huge number of errors that the program is not able to remove automatically, then you will have to correct the model yourself in the program where the model was originally created. In case of a large number of errors, the program will indicate their presence even after you have tried to do automatic treatment. The picture below is an example of a very large number of shortcomings and errors that the program is not able to remove by itself.

    This usually happens when the model is being prepared for rendering rather than 3D printing. That is, there is a huge number of surfaces, but they are not connected into a single grid.

    Fixing non-critical errors with Materialize Magic

    The 3D model healing feature in Materialize Magic is located in the Fix tab.

    After that, select the “Correction Wizard” command. Next, you need to alternate the “Update” and “Autocorrect” buttons.

    Do this several times. Sometimes for a long time. Until the moment when the number of errors becomes minimal or disappears altogether.

    After the upgrade, the result shown below can be considered successful. All checkboxes must be green.

    Complete the treatment by following the recommendations and save the corrected model!

    A very important point! Treatment in automatic mode occurs according to the principle of adding or removing polygons. Therefore, after automatic treatment, fully check the model for the correct form.
