How Does Metal 3D Printing Work?
The DMLS machine begins sintering each layer—first the support structures to the base plate, then the part itself—with a laser aimed onto a bed of metallic powder. After a cross-section layer of powder is micro-welded, the build platform shifts down and a recoater blade moves across the platform to deposit the next layer of powder into an inert build chamber. The process is repeated layer by layer until the build is complete.
When the build finishes, an initial brushing is manually administered to parts to remove a majority of loose powder, followed by the appropriate heat-treat cycle while still fixtured in the support systems to relieve any stresses. Parts are removed from the platform and support structures are removed from the parts, then finished with any needed bead blasting and deburring. Final DMLS parts are near 100 percent dense.
Large Format Metal 3D Printing
We recently added the GE Additive X Line to our fleet of metal 3D printers to build large Inconel 718 and Aluminum (AlSi10Mg) parts.

SLA Material Options
ABS-Like White (Accura Xtreme White 200)
ABS-Like White (Accura Xtreme White 200) is a widely used general purpose SLA material.
In terms of flexibility and strength, this material falls between molded polypropylene and molded ABS, which makes it a good choice for functional prototypes. Parts as large as 29 in. x 25 in. x 21 in. can be built with ABS-Like White so consider it a primary option if you require an extensive part size build envelope.
Primary Benefits
- Durable, general purpose resin
- Accommodates extra-large parts
ABS-Like Gray (Accura Xtreme Gray)
ABS-Like Gray (Accura Xtreme Gray) is a widely used general purpose SLA material. In terms of flexibility and strength, this material falls between molded polypropylene and molded ABS, which makes it a good choice for functional prototypes. ABS-Like Gray offers the highest HDT of the ABS-like SLA resins.
Primary Benefits
- Durable, general purpose resin
- Highest HDT of the ABS-like SLA resins
ABS-Like Black (Accura 7820)
ABS-Like Black (Accura 7820) is a widely used general purpose material.
Its deep black color and glossy up-facing surfaces in a top profile offer the appearance of a molded part, while layer lines may be visible in a side profile. RenShape 7820 also has low moisture absorption (0.25% per ASTM D570) so that parts are more dimensionally stable. Compared to other SLA materials, it has midrange values for all mechanical properties.
Primary Benefits
- Low moisture absorption
- Glossy cosmetic appearance
ABS-Like Translucent/Clear (WaterShed XC 11122)
ABS-Like Translucent/Clear (WaterShed XC 11122) offers a unique combination of low moisture absorption (0.35% 0.25% per ASTM D570) and near-colorless transparency. Secondary operations are required to achieve functional part clarity, and the part will also retain a very light blue hue afterward. While good for general-purpose applications, WaterShed is the best choice for flow-visualization models, light pipes, and lenses.
Primary Benefits
- Lowest moisture absorption of SLA resins
- Functional transparency
MicroFine™ (Gray and Green)
MicroFine™ is a custom formulated material available in gray and green that is exclusive to Protolabs.
This ABS-like thermoset is printed in Protolabs’ customized machinery to achieve high resolution features as small as 0.002 in. MicroFine is ideal for small parts, generally less than 1 in. by 1 in. by 1 in. In terms of mechanical properties, MicroFine falls in the mid-range of SLA materials for tensile strength and modulus and on the low end for impact strength and elongation.
Primary Benefits
- Produces highest resolution parts
- Ideal for extra-small parts
PP-Like Translucent White (Somos 9120)
PP-Like Translucent White (Somos 9120) is the most flexible SLA option outside of Carbon RPU 70 and FPU 50. In direct comparison to the average values of an injection-molded polypropylene, 9120 has similar tensile strength, tensile modulus, flexural modulus, and impact strength. The only departure from molded PP is its elongation value, which is only 25% of the molded thermoplastic.
Primary Benefits
- Semi-flexible
- Translucency
PC-Like Advanced High Temp (Accura 5530)
PC-Like Advanced High Temp (Accura 5530) creates strong, stiff parts with high temperature resistance.
A thermal post-cure option can increase HDT as high as 482°F at 0.46 MPa loading. Accura 5530 has the highest E-modulus of all the unfilled SLA materials, and it is known for being resistant to automotive fluids. However, the thermal curing process does make Accura 5530 less durable, resulting in a 50% reduction to elongation.
Primary Benefits
- High elastic modulus
- Higher resistance to heated fluids
PC-Like Translucent/Clear (Accura 60)
PC-Like Translucent/Clear (Accura 60) is an alternative to the general purpose ABS-like materials and WaterShed XC 11122 when stiffness is desired. Like WaterShed, this material can be custom finished to achieve functional transparency with secondary processing. Accura 60 has the highest tensile strength of and elastic modulus compared of all SLA materials outside of the Advanced High Temp options that are most often thermal cured.
Primary Benefits
- High stiffness
- Functional transparency
Ceramic-Like Advanced HighTemp (PerFORM)
Ceramic-Like Advanced HighTemp (PerFORM) exhibits the highest tensile strength and E-modulus making it the stiffest performance material of the SLA materials.
When the thermal cure option is applied to parts made from PerFORM, it exhibits the highest HDT (as high as 514°F at 0.46 MPa loading) of the SLA materials.
Primary Benefits
- Stiffest SLA resin
- Highest HDT of SLA resins

Metal Plating
Our metal-plating process for SLA coats a ceramic-filled PC-like material (Somos PerFORM) with a nickel that gives parts the look, feel, and strength of metal, but without the weight.
The combination of the material’s strength, rigidity, and temperature resistance with nickel plating, takes strength, stiffness, and impact and temperature resistance to a degree previously unattainable in SLA parts.
Microfluidics
Our microfluidic fabrication process is a modified form of high-resolution SLA that uses a clear ABS-like material (WaterShed XC 11122). Parts are resistance to water and humidity, and work well for lens and flow-visualization models.
Our SLA 3D Printers
Our stereolithography machines consists of Vipers, ProJets, and iPros. In high-resolution mode, Vipers and ProJets can make parts with extremely tiny features and crisp details, while in normal-resolution mode, they can build cost-effective parts very quickly.
iPros have extremely large build volumes at 29 in. by 25 in. by 21 in. (736mm by 635mm by 533mm), yet are still able to image highly detailed parts easily.
Why Use SLA?
Stereolithography (SLA) is an additive manufacturing process that can 3D print parts with small features, tight tolerance requirements, and smooth surface finishes.
How Does SLA 3D Printing Work?
The SLA machine begins drawing the layers of the support structures, followed by the part itself, with an ultraviolet laser aimed onto the surface of a liquid thermoset resin. After a layer is imaged on the resin surface, the build platform shifts down and a recoating bar moves across the platform to apply the next layer of resin. The process is repeated layer by layer until the build is complete.
Newly built parts are taken out of machine and into a lab where solvents are used to remove any additional resins. When the parts are completely clean, the support structures are manually removed. From there, parts undergo a UV-curing cycle to fully solidify the outer surface of the part. The final step in the SLA process is the application of any custom or customer-specified finishing. Parts built in SLA should be used with minimal UV and humidity exposure so they don’t degrade.

How to calculate the cost of printing on a 3D printer
For some ideas, 3D printing is the fastest and easiest solution.
In some situations, purchasing your own 3D printer can be a good solution, but sometimes it is much more profitable and faster to order the necessary product from a company specializing in 3D printing. Yes, and many owners of a 3D printer are thinking about how to “monetize” their hobby, but how to correctly calculate their costs?
Despite the fact that it is customary to indicate the price per gram of working material, simply multiplying the weight of the model by the cost of 1 gram will be wrong. In addition to the cost of consumables, many more, at first glance, non-obvious costs are added to the price of the product.
Each 3D printing technology uses its own consumables. Let's analyze the most popular and affordable of them.
Available technologies and key differences
Currently, a huge number of 3D devices have appeared, from small desktop ones that fit on the desktop to huge industrial machines. Among the most affordable, 2 technologies can be distinguished - FDM and photopolymer printers (LCD / DLP / SLA).
FDM 3D printing
Today, the most affordable 3D printing technology is FDM. A variety of materials and 3D printers allow FDM to be applied to a wide range of applications.
Schematic operation of FDM printer
A large selection makes it easy to choose a 3D printer for a specific task or find a universal device.
The material for printing is a plastic thread - filament. On the market you can find filament for various tasks, for every “taste” and budget. These can be very inexpensive ABS and PLA plastics or specific ones - conductive, burnable, etc.
Pros:
Cons:
Despite the fact that FDM allows you to print a wide range of plastics with different properties, the technology has some limitations. For example, it is impossible to obtain a perfectly smooth surface, to produce miniature and very thin elements, or to produce parts with very complex internal geometry with high accuracy.
Photopolymer printing
Photopolymer printers can work on one of 3 technologies - SLA, DLP or LCD. These devices will come to the rescue if you need to make a small but very detailed model with many small details.
How photopolymer printers work
As a consumable material, a photopolymer resin hardened by UV radiation is used. Now there is a wide variety of photopolymer resins for every taste. From particularly strong and precise engineering or jewelry resins to soft flexes.
Pros:
-
High print precision
-
Good surface quality
-
A wide variety of printers and consumables
Minuses:
Photopolymer printers have shown themselves well in a variety of industries that require a perfectly smooth surface and high accuracy. They are used in dentistry, the jewelry industry, for making miniature master models for casting, and much more.
Industrial printers
These are already industrial machines, which require a separate room and sometimes certain requirements for ventilation, etc. In this article, we will not analyze these devices in detail, but briefly consider the most popular technologies.
FDM
In addition to desktop devices using FDM technology, industrial printers that work on the same principle are common.
This category includes devices with a large print area (from 30x30x30 cm and more). For example, Raise Pro2 with a print area of 30x30x30 cm.
Raise Pro2
Or machines designed for printing with refractory materials (eg PEEK). Such 3D printers usually have an active thermal chamber, and the extruder can be heated above 400 degrees.

Photopolymer printers
Industrial photopolymer devices usually have a much larger working area, compared to their "home" brothers.
In addition, many processes have been optimized and automated for faster operation. On such printers, you can quickly and accurately produce a small batch of models, a large prototype or a master model.

3DP
3DP - Three-Dimensional Printing (translated as three-dimensional printing) is a logical continuation of conventional two-dimensional printers. Printing is done using nozzles that selectively apply a binder to the material (usually gypsum). A dye can be added to the binder and the model will be colored.
Colored plaster model
Since the plaster model is fragile, a similar principle is used for printing with metals. Only the finished product needs to be treated in an oven to remove the binder and improve strength. But despite the processing, such metal prints will still be inferior in strength to cast products.
MJM
This is a proprietary technology of 3D Systems. MJM is a mix of FDM, 3DP and sometimes SLA (depending on material chosen). Printing is done using a variety of small nozzles (from 96 to 488) located on the head of the machine. The accuracy and quality of the surface of models made in this way is in no way inferior to photopolymer printers.
Models made with MJM technology
Such devices can work with photopolymer resins, wax or thermoplastics. You can combine several materials at once - for example, for complex models, you can use wax as a support.
SLM
SLM is the layer-by-layer sintering of metal powder using a powerful laser. There are several similar technologies - SHS/SLS. The principle of operation is the same, only a thermal print head is used instead of a laser beam.
SLM Turbine
As a material for printing, you can use powders of various metals - gold, stainless steel, aluminum, various alloys, etc.
During printing, the working chamber is filled with an inert gas to prevent oxidation of metals. This allows printing even with titanium powder.
Models made by this method are in no way inferior, and sometimes even superior, to cast products. SLM allows you to produce models with complex internal geometry that cannot be produced by another method (casting or milling).
Cost of 3D printing
The cost of a model usually consists of several factors.
-
Equipment depreciation. The printer, like any machine, requires maintenance and periodic replacement of some parts. During operation, belts gradually stretch, bushings or linear bearings wear out. For example, when bushings or linear bearings are worn; shafts may wear out and need to be replaced.
Cost of materials
The main cost item for a 3D printer is, of course, the printed material.;
FDM (plastic filament)
Since FDM technology is by far the most common, the choice of filaments is very diverse.
-
Engineering plastics are usually nylon with various fillers added to improve the physical characteristics of the finished model. Special cost. plastics starts from 2000r per coil and above. It all depends on the manufacturer and filler (carbon fiber, fiberglass, etc.).
-
Decorative plastics are used to imitate various materials. Plastic can simply be unusually colored (luminous, transparent plastics) or a special filler is added to it (plastics with metal powder). The cost of decorative plastics starts from 1500 rubles per coil and more, depending on the filler.
A big advantage of FDM is the diverse choice of materials to work with. This allows, having one printer, to produce almost any product - from a child's toy to a complex engineering prototype.
Photopolymers (resin)
Photopolymer resin printing technology is becoming more and more accessible. There are many different resins.
-
The cost of ordinary colored resin starts from 2500 rubles per 0.5 kg (volume +/- 0.5 l). You can find a smaller volume of resin (250 gr) on sale. You can buy several different resins in small containers and find out in practice which one is best for a particular model.
-
Engineering resins are resins with increased strength. They can be used not only for printing decorative items, but also for making functional prototypes and models. The cost for 0.5 kg starts from 5900r and above.
-
Special resins - burnable, dental, soft flexes, etc. Depending on the resin, the price for 0.5 kg can start from 4800 rubles and more. It all depends on the characteristics of the resin.
Photopolymer resins have not yet reached such a variety as FDM filaments, but they are surely catching up. Although due to the fact that a liter of resin costs significantly more than a spool of filament, the cost of the product is much higher.

The models were bought on the myminifactory website (the cost of the model is from $2). Made with a desktop DLP printer. Post-processing was not required. The cost of the finished figurine is from 70 r per gram.
Custom 3D printing
Many owners of 3D printers are thinking about monetizing their hobby. But you should understand that the price of 3D printing “for yourself” and the price of commercial printing are very different.
When starting to print to order, it is better to have several printers working on different technologies.
Cost of commercial 3D printing
In addition to the cost of the model, to the commercial production of products, you can add:
-
Modeling. Often the client needs not only to make a part, but to pre-model it. It can be a simple cogwheel that doesn't take long to model, or it can be a complex sculpture that takes more time to model than it does to make.
-
Model post-processing. This can be simply the removal of supports, with cleaning of the place of their contact with the product, or a complete processing cycle (puttying, surface grinding, painting, etc.).
It should be borne in mind that it is not always possible to print the model the first time. Sometimes it may take several attempts. And these are additional costs.
What is unprofitable to print
Despite the wide possibilities of 3D printing, there are models that are unprofitable to make on a 3D printer.
For such models, it is better to use other manufacturing methods.
Commercial print examples
Jewelry for further casting
Manufacture of promotional items and souvenirs
Piece miniatures or master model for further casting
3D printed model
Profitable to print on a 3D printer:
-
If the item is only sold as an assembly. For example, a small gear broke in the mechanism, but the mechanism is sold only “assembly”. It is much cheaper to make the desired gear on a 3D printer than to buy the entire mechanism.
-
A small batch of parts. Small batches, especially models with complex geometry, are more profitable to produce on a 3D printer than by casting or other methods.
Totals
If you need several models or a small project, sometimes it will be more expedient to outsource manufacturing.
After all, in addition to buying equipment and materials, you will have to understand the nuances of the settings and the characteristics of various materials.
Buying a 3D printer for commercial use is justified if you can fully load it with work or then it can be used for other purposes.
To print to order, you need to have several printers working on different technologies. It is better to get several devices with a smaller print area than to buy just one printer, albeit with a large working area.

3D printing is one of the most promising areas of technological development in the 21st century.
Having gone a long way from bulky and heavy boxes to compact desktop devices, 3D printers have ceased to be something inaccessible to a wide range of users. The era of mass additive manufacturing has already arrived, and every home can now house a real desktop factory.
You can buy a 3D printer capable of printing small models and prototyping of medium complexity today at the price of an entry-level laptop. The price of PLA or ABS plastic, which acts as a consumable, also no longer seems exorbitant. In a word, if you have long dreamed of getting to know the world of 3D printing and joining the ranks of makers, the right moment has come!
To save you time and make it easier to select equipment, we have collected in one section all desktop 3D printers optimized for home and office use. These are the real "workhorses" with the perfect balance of functionality, quality and price. Even a beginner can understand the settings, mount and calibrate a 3D printer, and as he gains experience, he will be able to print more and more complex three-dimensional models.
