Formlabs desktop 3d printer

Types of 3D Printers, Materials, and Applications

3D printing or additive manufacturing (AM) technologies create three-dimensional parts from computer-aided design (CAD) models by successively adding material layer by layer until physical part is created.

While 3D printing technologies have been around since the 1980s, recent advances in machinery, materials, and software have made 3D printing accessible to a wider range of businesses, enabling more and more companies to use tools previously limited to a few high-tech industries.

Today, professional, low-cost desktop and benchtop 3D printers accelerate innovation and support businesses in various industries including engineering, manufacturing, dentistry, healthcare, education, entertainment, jewelry, and audiology.

All 3D printing processes start with a CAD model that is sent to software to prepare the design. Depending on the technology, the 3D printer might produce the part layer by layer by solidifying resin or sintering powder. The parts are then removed from the printer and post-processed for the specific application.

See how to go from design to 3D print with the Form 3 SLA 3D printer. This 5-minute video covers the basics of how to use the Form 3, from the software and materials to printing and post-processing.

3D printers create parts from three-dimensional models, the mathematical representations of any three-dimensional surface created using computer-aided design (CAD) software or developed from 3D scan data. The design is then exported as an STL or OBJ file readable by print preparation software.

3D printers include software to specify print settings and slice the digital model into layers that represent horizontal cross-sections of the part. Adjustable printing settings include orientation, support structures (if needed), layer height, and material. Once setup is complete, the software sends the instructions to the printer via a wireless or cable connection.

Some 3D printers use a laser to cure liquid resin into hardened plastic, others fuse small particles of polymer powder at high temperatures to build parts. Most 3D printers can run unattended until the print is complete, and modern systems automatically refill the material required for the parts from cartridges.

With Formlabs 3D printers, an online Dashboard allows you to remotely manage printers, materials, and teams.

Depending on the technology and the material, the printed parts may require rinsing in isopropyl alcohol (IPA) to remove any uncured resin from their surface, post-curing to stabilize mechanical properties, manual work to remove support structures, or cleaning with compressed air or a media blaster to remove excess powder. Some of these processes can be automated with accessories.

3D printed parts can be used directly or post-processed for specific applications and the required finish by machining, priming, painting, fastening or joining. Often, 3D printing also serves as an intermediate step alongside conventional manufacturing methods, such as positives for investment casting jewelry and dental appliances, or molds for custom parts.

The three most established types of 3D printers for plastics parts are stereolithography (SLA), selective laser sintering (SLS), and fused deposition modeling (FDM). Formlabs offers two professional 3D printing technologies, SLA and SLS, bringing these powerful and accessible industrial fabrication tools into the creative hands of professionals around the world.

Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is still one of the most popular technologies for professionals. SLA 3D printers use a laser to cure liquid resin into hardened plastic in a process called photopolymerization.

SLA resin 3D printers have become vastly popular for their ability to produce high-accuracy, isotropic, and watertight prototypes and parts in a range of advanced materials with fine features and smooth surface finish. SLA resin formulations offer a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics.

Resin 3D printing a great option for highly detailed prototypes requiring tight tolerances and smooth surfaces, such as molds, patterns, and functional parts. SLA 3D printers are widely used in a range of industries from engineering and product design to manufacturing, dentistry, jewelry, model making, and education.

Learn More About SLA 3D Printers

Stereolithography (SLA) 3D printing uses a laser to cure liquid photopolymer resin into solid isotropic parts.

SLA parts have sharp edges, a smooth surface finish, and minimal visible layer lines.

Selective laser sintering (SLS) 3D printers use a high-power laser to sinter small particles of polymer powder into a solid structure. The unfused powder supports the part during printing and eliminates the need for dedicated support structures. This makes SLS ideal for complex geometries, including interior features, undercuts, thin walls, and negative features. Parts produced with SLS printing have excellent mechanical characteristics, with strength resembling that of injection-molded parts.

The most common material for selective laser sintering is nylon, a popular engineering thermoplastic with excellent mechanical properties. Nylon is lightweight, strong, and flexible, as well as stable against impact, chemicals, heat, UV light, water, and dirt.

The combination of low cost per part, high productivity, and established materials make SLS a popular choice among engineers for functional prototyping, and a cost-effective alternative to injection molding for limited-run or bridge manufacturing.

Learn More About SLS 3D Printers

SLS 3D printers use a high-powered laser to fuse small particles of polymer powder.

SLS parts have a slightly rough surface finish, but almost no visible layer lines.

Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used type of 3D printing at the consumer level. FDM 3D printers work by extruding thermoplastic filaments, such as ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid), through a heated nozzle, melting the material and applying the plastic layer by layer to a build platform. Each layer is laid down one at a time until the part is complete.

FDM 3D printers are well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts, such as parts that might typically be machined. However, FDM has the lowest resolution and accuracy when compared to SLA or SLS and is not the best option for printing complex designs or parts with intricate features. Higher-quality finishes may be obtained through chemical and mechanical polishing processes. Industrial FDM 3D printers use soluble supports to mitigate some of these issues and offer a wider range of engineering thermoplastics, but they also come at a steep price.

Learn More About FDM 3D Printers

FDM 3D printers build parts by melting and extruding thermoplastic filament, which a printer nozzle deposits layer by layer in the build area.

FDM parts tend to have visible layer lines and might show inaccuracies around complex features.

Having trouble finding the best 3D printing process for your needs? In this video guide, we compare FDM, SLA, and SLS technologies, the most popular types of 3D printers, across the most important buying considerations.

Each 3D printing process has its own benefits and limitations that make them more suitable for certain applications. This video compares the functional and visual characteristics of FDM, SLA, and SLS printers 3D printers to help you identify the solution that best matches your requirements.

Do you need custom parts or prototypes fast? Compared to outsourcing to service providers or using traditional tools like machining, having a 3D printer in-house can save weeks of lead time. In this video, we compare the speed of FDM, SLA, and SLS 3D printing processes.

Comparing the cost of different 3D printers goes beyond sticker prices—these won’t tell you the full story of how much a 3D printed part will cost. Learn the three factors you need to consider for cost and how they compare across FDM, SLA, and SLS 3D printing technologies.

As additive manufacturing processes build objects by adding material layer by layer, they offer a unique set of advantages over traditional subtractive and formative manufacturing processes.

With traditional manufacturing processes, it can take weeks or months to receive a part. 3D printing turns CAD models into physical parts within a few hours, producing parts and assemblies from one-off concept models to functional prototypes and even small production runs for testing. This allows designers and engineers to develop ideas faster, and helps companies to bring products more quickly to the market.

Engineers at the AMRC turned to 3D printing to rapidly produce 500 high-precision drilling caps used in drilling trials for Airbus, cutting the lead time from weeks to only three days.

With 3D printing, there’s no need for the costly tooling and setup associated with injection molding or machining; the same equipment can be used from prototyping to production to create parts with different geometries. As 3D printing becomes increasingly capable of producing functional end-use parts, it can complement or replace traditional manufacturing methods for a growing range of applications in low- to mid-volumes.

Pankl Racing Systems substituted machined jigs and fixtures with 3D printed parts, decreasing costs by 80-90 percent that resulted in $150,000 in savings.

From shoes to clothes and bicycles, we’re surrounded by products made in limited, uniform sizes as businesses strive to standardize products to make them economical to manufacture. With 3D printing, only the digital design needs to be changed to tailor each product to the customer without additional tooling costs. This transformation first started to gain a foothold in industries where custom fit is essential, such medicine and dentistry, but as 3D printing becomes more affordable, it’s increasingly being used to mass customize consumer products.

Gillette's Razor Maker™ gives consumers the power to create and order customized 3D printed razor handles, with the choice of 48 different designs (and counting), a variety of colors, and the option to add custom text.

3D printing can create complex shapes and parts, such as overhangs, microchannels, and organic shapes, that would be costly or even impossible to produce with traditional manufacturing methods. This provides the opportunity to consolidate assemblies into less individual parts to reduce weight, alleviate weak joints, and cut down on assembly time, unleashing new possibilities for design and engineering.

Nervous System launched the first-ever 3D printed ceramic jewelry line, consisting of intricate designs that would be impossible to manufacture using any other ceramic technique.

Product development is an iterative process that requires multiple rounds of testing, evaluation, and refinement. Finding and fixing design flaws early can help companies avoid costly revisions and tooling changes down the road. With 3D printing, engineers can thoroughly test prototypes that look and perform like final products, reducing the risks of usability and manufacturability issues before moving into production.

The developers of Plaato, an optically clear airlock for homebrewing, 3D printed 1,000 prototypes to fine tune their design before investing in expensive tooling.

3D printing accelerates innovation and supports businesses across a wide range of industries, including engineering, manufacturing, dentistry, healthcare, education, entertainment, jewelry, audiology, and more.

Rapid prototyping with 3D printing empowers engineers and product designers to turn ideas into realistic proofs of concept, advance these concepts to high-fidelity prototypes that look and work like final products, and guide products through a series of validation stages toward mass production.

Review of Formlabs Form 3 photopolymer 3D printer. Formlabs 2 VS Formlabs 3

Hello, Friends! 3DTool is with you!

Formlabs is one of the world's leading manufacturing companies in the field of additive manufacturing. Form 3D Printers became famous in 2011, when a young team of developers started their journey in the laboratory of the Massachusetts Institute of Technology. However, a serious approach became visible already from the first attempts, since the technical task was to create the most automated device that does not require the user to have special skills in working with 3D printers and its settings. We must pay tribute to the team, they coped with the task « to excellent ” and after a successful campaign on “ Kickstarter ”, the first 3D printer from the manufacturer FormLabs – Form 1 was presented to the public. Of course, the printer had certain childhood diseases and rough edges, but the precedent set in SLA technology certainly stirred up the market. In today's review, we got a representative of the third version of this equipment - Formlabs Form 3 . Let's take a closer look at what Form 3 is, where and how it can be used, and what are the advantages over analogues on the market SLA 3D printers.

1. What is Formlabs Form 3?

Form 3 photopolymer 3D printer with a rich history of predecessors, a competent approach to development and one of the best, if not the best in its class. Thousands of previous Formlabs models have worked successfully in every industry imaginable and have performed well. Form 3 first of all, it is powerful and easy to use, the most automated SLA (LFS) 3D printer . By using proprietary FormLabs cartridges with different properties, the risk of printing errors is minimized. Everything is thought out for the user.

So what is Form 3 ?

Form 3 is a professional-grade desktop stereolithographic 3D printer for adequate money. This is a great and thoughtful design, convenient and smart software. As well as a real ecosystem FormLabs includes: Form 3 3D printer, Pre-Form software, photopolymers of various properties and types, Form Wash and Form Cure post-processing systems, as well as a powerful user community. FormLabs Form 3 is an automated working solution for SLA (LDS) 3D printing of out of the box, requiring no special knowledge from the user. Follow the instructions on the screen and everything will work by itself. Working with various photopolymer 3D printers, our 3Dtool engineers said unanimously: this 3D printer - Iphone, among the variety of models SLA / DLP 3D printers . Those. everything is also convenient and thoughtful, reliable as in products from Apple .

2. An overview of photopolymer resins from FormLabs.

Thanks to a wide range of photopolymers with different properties, Form 3 is used everywhere, where high surface quality and ease of use are required.

Starting from engineering workshops, prototyping departments, continuing with hobbyists and collectors of miniatures and wargames, and ending with medicine - dentistry and surgery. Let's start in order:

Hobbies and prototyping.

In the basic version, the printer comes with one polymer cartridge - Standard Gray . It allows you to achieve high quality printing, while not requiring excessive post-processing. It is enough to wash the product with isopropyl alcohol from the excess of uncured photopolymer.

Photopolymer resin "Standard" comes in several colors and is considered "basic", it is used, for example, in prototyping or prototyping of any parts that do not require special properties, but with a high-quality surface of the part. This is the basic type of photopolymers Formlabs .

If necessary, you can also use a transparent version of the material. If you need to print elements with a certain light transmission. For example, a display on the body of the device, or a transparent glazing of a car model. This material is also optimized for printing master models for subsequent casting in silicone.

The color of the resin also affects its properties.

For example, Gray Standard resin is suitable for models with fine details, while White Standard resin is suitable for parts that require an extremely smooth surface.

Another material in this range is Draft Resin, which is specifically honed for really fast SLA 3D printing at 300 microns (or 0. 3mm) if you need fast results in a limited amount of time.

This is followed by a line of engineering photopolymers.

Functional samples.

Engineering materials are represented by a wide range of photopolymers with various useful mechanical and isotropic properties. First of all, these materials are used in functional prototypes, in complex products that require different physical properties from its elements and, if necessary, to make something that will be actually used and work, and not just demonstrate the concept itself.

The first three materials are Resin Gray Pro Resin , Rigid Resin and Durable Resin . The first, as you might guess, is an improved version of the standard material and allows you to perform lightly loaded mechanisms with rubbing parts, has low shrinkage and good viscosity.

The second type of resin is Riged Resin , a high hardness reinforced composite, excellent for thin wall applications and various blades and fans.

The third type of resin - Durable Resin , resembles nylon in properties, it should be used in parts loaded with friction.

Three special materials follow - Elastic Resin , Flexible Resin and Hight Temp Resin . You can already guess from the name that the first two are Formlabs elastic resins with slightly different stiffnesses and appearance, but their main area of application is where the production of flexible products is required.

Elastic Resin is the softest 50A Shore A hardness engineered polymer in the Formlabs range. It is great for prototyping models usually made from silicone. Elastic Resin should be chosen for models that will need to bend, stretch, compress and withstand repeated cycles without breaking.

Flexible Resin is used primarily for low-deformation flexible models. With a hardness of 80A Shore and a soft touch matt black finish, this polymer is the choice for ergonomics in larger assemblies. It is ideal for cushioning and damping, wearable and consumer product prototypes, handles, grips and pads.

High Temp Resin - high temperature photopolymer resin from FormLabs, the main property of which is heat resistance up to 238 degrees Celsius. This photopolymer is also very durable and can be used in thermally stressed environments.

The most common of the engineering materials is Tough Resin, its balanced strength characteristics perfectly withstand variable loads. It is quite light but does not lose strength and can be used, for example, for a quadrocopter frame.

Jewelry and stencils.

Formlabs offers two resin options for this application.

These are burnt out photopolymer resin and burnt out wax.

Castable Wax Resin is a 20% wax polymer that provides reliable casting with zero ash and clean burnout. It accurately renders complex elements and produces the smooth surface that stereolithographic 3D printing is known for. The printed models are durable, do not need additional illumination, and are ready for try-in and investment casting immediately after printing.

Castable Resin differs from the previous material in a new and original formula for investment casting. The burn-off curve for this resin is different from the standard wax burn-off curve. That allows you to use it when working with particularly thin elements of injection models and better optimize the process itself.

Medicine. Surgery and dentistry.

One of Formlabs' most sought-after product lines is dentistry. The company offers several types of biocompatible resins.

For example, Dental Model is a high-precision printing material for creating models of dentures and the production of transparent aligners. The main advantage of the material is a low degree of shrinkage, which allows printing products with clear edges and contacts within ± 35 µm. It is ideal for printing crown and bridge models, clear aligner models, orthodontic models, diagnostic models, dental implant models.

Another biocompatible resin used in dentistry is Dental SG. This material has high heat resistance and allows disinfection of items made from it in autoclaves. Due to its characteristics, it is used to 3D print precise surgical templates, allowing dentists to accurately position implants.

guides and templates for drilling teeth and jaws.

Another material for dentistry is Dental LT Clear Resin. Long lasting clear biocompatible photopolymer for printing tires and nightcaps.

Also, when creating prostheses and other dental products by pressing, they use the already familiar Castable Wax Resin , which is used in the manufacture of cast caps and intraosseous parts of implants, cast crowns and crowns made by pressing and cast partial removable frames of dentures.

3. Formlabs Form3 Features, Package Contents and Appearance.

Let's start with the specs first:

For comparison, Form 2 had a smaller working area - only 175 mm in height, and also had a less advanced material mixing system. The Form 3 also uses a completely new laser optical system to illuminate the photopolymer.

The package, however, has not changed much. A standard set of various cuvettes for product processing, a huge bag of disposable gloves and the necessary tools.

And if you do not see the printer with your own eyes, you might think that it has not changed at all.

No matter how!

Form 3 differs markedly from its predecessors, which it replaced. First of all, the dimensions are striking. It is clearly larger than the old model, primarily due to the improved mixing and lighting system, but more on that later.

The control display has moved to the middle of the front panel. Removed all unnecessary buttons, now the printer is controlled exclusively from the touch panel.

Added a convenient opening handle on the protective cap and a very stylish Formlabs logo in the lower left corner.

The sides of the printer are empty, on the back wall there are well-known connectors:

Ethernet, USB, power connector and service information with printer serial number.

When you open the lid, you can see a solid ball screw, a convenient print platform bracket with branded fasteners, a modified cuvette and a mixing system that now works on two levels.

4.

What has changed in the new device in terms of the technical part?

First of all, the approach to working with the material has changed. Although Form 3 is called an SLA 3D printer, in fact, the new technology is called LFS (Low Force Stereolithography)

Which uses a flexible cuvette and additional linear illumination, like on scanners, to achieve the ideal print quality and reliability.

The laser illumination system of the device has also undergone a major change:

The use of a new more powerful laser with a high beam density, a special spatial filter and parabolic lenses made it possible to achieve, together with improved layer registration and additional surface illumination, really impressive results.

With the same layer thickness and standard parameters, the Form 3 noticeably outperforms the previous From2 model in terms of surface smoothness and line accuracy.

Also, the device has acquired several new sensors that control the 3D printing process and the flow of material into the cuvette, which greatly increased fault tolerance. However, the printer still needs to be leveled using a special menu on the display during the first start. The process itself is necessary to make sure that the liquid level in the cuvette is not skewed and there will be no overflows when printing on the model. In other words, in this way the system double-checks that the printer itself is perfectly level on your table, without skew.

5. Interface and software.

The functionality of the interface has not undergone major changes.

On the left side of the screen, we can switch between different settings - Main Screen, Print Queue, Printer Status and an impressive settings menu.

In the last menu of the list, all the necessary settings are available to us. From network connection, to firmware updates and manuals for self-replacement of the LPU (additional illumination module) Yes, it is understood that the user can do it himself.

The software is a Pre-From slicer, let's connect our printer and move on to the 3D printing process. After installing the program from the manufacturer's website.

As you can see, the cartridge is already installed in the Formlabs Form 3 printer, and the printer itself is connected to the computer via a USB cable. PreForm has already automatically detected which photopolymer is installed. This is the very convenience of automating the process. You only need to load the cartridge and select the settings.

Let's load the model. We will print parts of a miniature soldier from a desktop wargame. At the same time, let's see how the printer copes with fine detail.

So let's choose a model.

Now you need to select all the parts, perform automatic repair, and then place the parts on the table. By the way, the program also does this automatically by pressing the corresponding key.

Supports are also generated automatically, but you still have full-fledged functionality for your own customization. Everything can be configured. From the thickness of the layer, to the size of the point of contact of the supporting column with the surface of the product.

We prepare all our files and send them for printing.

6. 3D printing process.

After sending the model to print, PreForm will alert us to check the process on the printer screen.

Here we only need to press the print button and wait for the process to finish. Which, by the way, will take an hour and 20 minutes. Which is pretty good for a product with a 50 micron layer thickness.

Well, the result was not long in coming! The quality turned out great. Even at 50 microns, although the printer can print at 25 microns of quality, all the detail is captured perfectly.

And here is our soldier in comparison with the factory prototype. Not a big difference.

We will print a few more products to make sure the quality of the printer.

7. Result.

Well, the printed products speak for themselves. The ring is printed with thin walls and a 50 µm layer.

The denture is 25 microns, its surface is just perfect.

The well-known couple baby Yoda and his friend the Mandalorian, 100 microns, so as not to spend a lot of time printing.

The result is excellent.

8. Summary.

Well, in summary, let's go over the main advantages of the model once again and determine where this 3D printer can be used with the greatest success.

With improved print control systems and multiple sensors, the Form 3 delivers the most consistent print experience, a huge improvement over the company's previous models.

The new polymer illumination system using additional illumination and a flexible cuvette makes it possible to achieve the best quality and the absence of sags and overflows on the surface of the model, and also has a positive effect when printing at high quality - 50 microns or less.

The expanded list of photopolymer resins expands the already extensive list of applications and deepens existing examples.

At the same time, it remains affordable both in price ( compared to industrial analogues ), and in terms of ease of learning the printing process and using the printer.

The Form 3 will make a great workbench on the table of the dental technician and dentist, as well as in the jewelry shop, or even the jewelry factory, thanks to the ability to print with high-performance burnout resins with a minimum ash content. At the same time, the use of engineering materials implies the printing of functional prototypes with various functions, which will be indispensable when working in an engineering bureau, design studio, or in a prototyping department in a large-scale production.

And thanks to its ease of use and a wide range of additional accessories, Form 3 will perfectly prove itself as a teaching tool in educational centers, CMITs and departments of prototyping and additive technologies of universities.

And that's all we have! We hope the review was useful to you.
