Essential tools for every 3D printing professional
Lana Lozova15 December 2020
News
To get the best from your 3D printer, you need to be armed with the right tools for the job. From removing support material to improving build plate adhesion, here’s a list of must-have tools, all designed to make your life easier.
The essential 3D printer owner’s toolkit
There are certain tools that most 3D printer users possess. These vital pieces of equipment ensure that your prints run smoothly, and that you get the best results possible. You don’t necessarily need to invest in them all at once – but over time, it’s likely you’ll end up adding them all to your tool collection.
Glue stick
Build plate adhesion is an important part of creating great 3D prints. Glue sticks come in particularly handy when you’re trying to get your print to stick – simply cover your print bed with soluble glue, and the adhesion will improve immediately. Some people favor hair spray, but we’d personally recommend glue, as you can be more precise with the application, plus there’s less risk of accidentally spraying the gantry or moving parts. For material-specific adhesion guidelines, check out this support article.
Spatula or palette knife
On occasion, you might find that your 3D print has stuck a bit too well to your build plate. When this happens, a spatula or palette knife normally solves the problem. All you’ll need to do is ease it gently under the print and carefully lift it up.
Over time, you’ll probably get a collection of different palette knives. To start with, we’d recommend getting a palette knife that’s stiff, and one that’s flexible. Titan’s stainless steel scrapers have a tapered tip, which we find works particularly well.
Deburring tool / knife and cutting mat
A deburring tool is great for cleaning up modeled holes, and for removing small pieces of plastic from your printed parts, especially brim. You’ll also need knives to tidy up your prints, as they seldom turn out completely perfect. A deft flick of the knife can remove unsightly plastic blobs or filament strings, making the end result look smoother and cleaner. We recommend investing in a knife with exchangeable blades (such as an X-Acto knife), and a cutting mat too.
Pliers
Pliers have a variety of uses, from print core maintenance to fixing your 3D printer. Look for a good quality pair of pliers with a rubberized, slip-resistant grip. You’re likely to need more than one type – we’d recommend needle nose and wire-cutting pliers (which are particularly useful for snipping away support material or trimming filament).
Blue tape
Masking tape is one of the most basic tools you’re likely to own, and also one of the most widely used.
Adding masking tape to the print bed is a simple, effective way to help your 3D printed object adhere to the print bed. It also makes removing the finished print far easier, and it protects your print bed from scratches.
Make sure you choose masking tape with a width of at least 50mm (2 inches). When the tape’s wide, it means you’ll need fewer strips to cover your print bed – something you’ll be grateful for if you need to resurface your print bed on a regular basis!
Magnalube and Unilube
Sometimes, you’ll need to lubricate the X and Y axles, just to ensure they keep running smoothly. The best lubricant to use is Unilube, and all it takes is a single drop to resolve any issues with dryness. For the Z trapezoidal leadscrew, use Magnalube.
It’s important not to use WD40, as this affects the axle coating and can cause damage to your printer. Read more about it here.
Digital caliper
A digital caliper has many applications in 3D printing. It’s useful for checking the precision of your prints, and you can also use it to dimension parts to replicate in CAD software.
Calipers are also handy for checking filament measurements – as filaments aren’t often manufactured to exact measurements. Simply measure it at a few different positions, average the readings, then adjust the filament diameter in your slicing software if necessary.
Analogue calipers work too, but don’t offer the same precision.
Tweezers
Tweezers are useful to have to hand whenever you’re printing. They’re great for plucking oozing filament from the extruder nozzle before it starts printing (which means no more burnt fingers). They’re also handy for cleaning up your print afterwards. We’d recommend purchasing a set of tweezers in various shapes and sizes, to ensure you’re covered for every eventuality.
Sandpaper
It’s a good idea to have a selection of sandpaper in a variety of different grits. These will all prove useful when you’re post-processing your 3D prints. Our recommendation? Have a selection from coarse (220 grit) to fine (1000 grit), and invest in well-known brands such as 3M, as they’re likely to last you longer than cheaper, inferior types.
Screwdrivers / hex key screwdrivers
Most people already own a good selection of screwdrivers and hex keys. If you don’t, it’s worthwhile getting some, as you’ll periodically need to re-tighten the gantry screws and the stepper motors of your 3D printer. Hex nuts and bolts are widely used in 3D printer assembly, so it’s also a wise idea to have a set of hex key screwdrivers and wrenches.
Adhesion sheets
Adhesion sheets are compatible with most materials, and boost adhesion to the build plate. They’re a good replacement for a glue stick, as they’re easy to remove and can be used multiple times. Another advantage is that they’ve been specially developed to cope with high temperatures, unlike masking tape. However, it’s important to check that the sheet is applied correctly, as air bubbles mean you won’t have a flat printing surface. You can find out how to apply the sheet here.
Desiccant and re-sealable bags
3D printer filament absorbs water over time.
This causes degradation, that eventually leads to complications during printing. To avoid water absorption, simply store your filament in a sealed container or plastic bag, and add some desiccant to ensure all moisture is removed from the environment. Silica gel works perfectly. Here are some more storage recommendations to help you. For a more automated solution, the Ultimaker S5 Material Station was developed to store and deliver material in optimal conditions for 3D printing.
Permanent marker
Permanent markers (such as Sharpies) are useful for marking 3D prints, especially when you’re running multiple prints of the same model, but with different slicer settings. Simply note down the sequence and settings for each print on the finished objects, and you’ll be able to tell them apart later on. Even leading architects do this: The team at Killa Design draw on their models to note where their design can be improved.
Advanced 3D Printing Kit
The Advanced 3D Printing Kit for Ultimaker 2+ contains two 0.
4mm nozzles, two TFM couplers, 25 adhesion sheets and a door. These keep your 3D printer running smoothly for longer. The nozzles and TFM couplers are convenient replacements, the adhesion sheets are great for keeping your models in position, and the door keeps warmth inside the printer, which prevents certain materials from warping and delaminating. Find out more here.
Other useful tools
The following tools might not be as essential as the list above, but they’re certainly useful to have around. Obviously, it depends on what you’ll be using your 3D printer for, as some are more suited to particular jobs than others.
Flashlight. If your 3D printer already has integrated lighting, you won’t need this. Otherwise, it’s a useful tool to have, even in well-lit areas. The inside of an enclosed 3D printer can be dark, which makes it different to judge print quality on detailed models. A compact LED light works perfectly.
Paper towels. Paper towels are always useful for cleaning and drying your build plate, and best of all, they’re cheap too!
Pencils and paper.
You’ll inevitably need to jot down dimensions and make sketches while printing, so it’s a good idea to have paper and pencils to hand at all times.Wire cutter. Wire cutters are excellent for removing support and creating a cleaner, neater finish.
Dremel. A Dremel is a handheld, high-speed rotary tool, which features a range of accessories. These accessories let you undertake a variety of applications, including cutting, sanding, carving and grinding. When you’re 3D printing, it can be used to remove support material, sand down rough edges, or polish 3D prints made from metal-containing filaments.
Extra filament. It’s always useful to have an additional filament spool to hand. A spool lasts a while, but won’t keep you printing forever! Also, it’s nice to have a variety to choose from, depending on your requirements.
Extra glass plate. If you are printing 24/7, having a spare glass plate could really speed up your workflow.
It allows you to quickly swap glass plates when starting a new print, instead of having to wait until the build plate has cooled down to remove the print.Dissolving kit (bucket of water and pump). You’ll need to be able to remove your water-soluble PVA after printing – and a bucket of water does the job nicely! A pump ensures PVA supports dissolve faster.
With the right tools, the chances of producing a flawless 3D print are greatly increased. A 3D printer and a computer do most of the hard work, but it’s the tools that polish and perfect the models afterwards!

Examples of positive and negative uses of a 3D printer
Every year 3D printing becomes more and more popular. The 3D printer, as a tool for turning a digital model into a physical object, is gaining popularity, outperforming other production methods in many ways due to its affordability.
But do not forget that a 3D printer is just a tool. A lot depends on how this tool will be used.
Available 3D printing technologies
All 3D technologies can be conditionally divided into 4 types.
nine0006
Layer by layer welding with molten material.
The principle of operation is similar to the familiar glue gun. The print media is melted to a semi-liquid state in the print head and applied with a nozzle to the print surface where it solidifies. This is how the finished 3D model “grows” layer by layer on the printing table. Not only thermoplastics can be used as consumables, but, for example, chocolate, icing, concrete, etc.
This is the most common type of printer. Inexpensive FDM printers are often used as home assistants. This is facilitated by an inexpensive price and a variety of consumables.
Selective curing of resin (photopolymer printers).
The material used is a photopolymer resin that hardens under the influence of UV radiation. As a source of UV radiation, a thin laser beam, a DLP projector or an LCD screen with a UV matrix, or any other design can be used. For example, some industrial 3D printers apply a photopolymer using thin nozzles and immediately illuminate it with a UV lamp.
nine0006
Previously, these printers were quite expensive. Today, with advances in technology, photopolymer 3D printing has become affordable and photoresin printers have become popular as home hobby printers.
Selective bonding of powdered material.
On the print head of the printer there are several nozzles through which a binder is supplied, which is selectively applied to the powdered material. Various materials can be used as a material: for example, gypsum or metal powders. But gypsum is most often used. nine0006
Since dye can be added to the "glue" during printing, such printers are usually used for the production of color demonstration models or souvenirs.
Laser sintering of powdered materials.
The youngest technology, but with great potential for use in large-scale industries. With the help of a laser or a heated print head, selective sintering of the metal powder occurs in an environment filled with an inert gas.
nine0006
These are already serious industrial printers that are used for the production of functional metal assemblies and parts. Currently, such 3D printers are actively used in the aerospace industry.
Unethical use
3D piracy
Where there is duplication of objects, there are always disputes about copyright and piracy.
The production of any product is a long and painstaking work, and often more than one person. Before you get a finished decorative product, for example, a figurine, you need to think through everything to the smallest detail. Usually, before modeling, the artist draws a lot of sketches, the details of clothing and accessories are thought out. Only after that the 3D modeler gets to work and begins painstakingly recreating the 3D model. nine0006
Functional models are often redesigned by engineers after the prototype has been made. There can be a very long way between the initial idea and a stable working mechanism.
And it’s very disappointing when such work is simply copied and posted in the public domain.
LEGO
It was one of the first mass manifestations of "3D piracy". At that time, 3D printing was only gaining popularity, and many users, having printed a dozen figurines, were looking for a useful application for a 3D printer. Given the low plastic consumption, the printed LEGO blocks were very inexpensive. nine0006
3D printed LEGO bricks
Despite the far from ideal surface, many were satisfied with such a copy. Some have argued that the accuracy of a home FDM printer is not enough for the bricks to fit well with the original LEGO, but for most users everything fit perfectly.
At the moment, LEGO is actively removing models that copy the original sizes of the famous bricks and men from the network. On popular sites, only custom elements of LEGO-men and LECO are left that are not the original size. nine0240
Custom heads for LEGO men
Games Workshop
Games Workshop, which produce the most expensive table soldiers in the world, sued Thomas Valenti (USA) back in 2012.
Thomas has modeled, printed and made publicly available several miniatures based on the Warhammer universe. The court sided with Games Workshop and the models had to be removed. nine0006
3D Printed Chaplain
Chaplain 3D model from Warhammer 40k
Games Workshop went one step further by banning fans from creating art and other work based on the original settings and characters. As a boycott, users of the Warhammer 40,000 section on Reddit are proposing to abandon the company's products as much as possible - print game figures on 3D printers, use paints from other companies, or switch to other universes. nine0006
Hollywood
The production of modern films is not a cheap pleasure, and film companies try to recoup their costs not only by showing them in cinemas, but, for example, by producing souvenirs.
DreamWorks has an entire consumer goods division that helps recoup the cost of a movie if it fails at the box office.
Film companies recognize that fan-made productions often surpass the official "souvenir" in accuracy and detail. nine0006
DC Universe Batman fan model
Many film companies are closely following the development of 3D printed merchandise, but do not yet know how to respond. For example, Paramount Pictures, Marvel Studios and Warner Bros. They themselves began to upload models for 3D printing to the network, before the release of new films.
Weapon Seal
Seal of weapons
24-year-old law student Cody Wilson was the first to make a gun on a 3D printer. Cody designed and 3D printed a combat pistol on his own. After 8 years, the idea of making firearms using 3D printing has not only not died out, but flared up with a bright fire. nine0006
It started in Texas in 2012. It was there that the company Defense Distributed was registered, the ideology of which was the development of models of firearms that anyone could make on a home 3D printer.
Guns
Liberator
The first “swallow” was the Liberator - a compact plastic pistol printed on a 3D printer from ABS plastic. The only thing that could not be made on a 3D printer was the striker, which was successfully replaced by an ordinary nail. The first printed pistol was made on a Stratasys Dimension SST 3D printer. nine0006
Liberator - the name is borrowed from a cheap pistol that was developed in 1942 in the USA.
The Liberator fired a fairly weak .380 ACP round and could only last a dozen rounds at most.
Failed Liberator
Zig Zag
In the spring of 2014, a video appeared on the Internet with a man shooting from a plastic revolver with a huge drum. The video greatly stirred up all of Japan. nine0006
Zig Zag
Unknown was Yoshitomo Imura (Yoshitomo Imura) - 28-year-old employee of the Shonan Institute of Technology.
Despite Imuru's claim that he fired blanks on the tape, he was arrested and sentenced to 2 years in prison.
The Zig Zag design was a reimagining of revolvers popular in the 19th century, which used a rotating .38 caliber barrel block mounted on a pistol grip. nine0006
Washbear
In 2015, mechanical engineering student James Patrick posted a video online showing a 3D printed PM522 Washbear in operation.
PM522 Washbear
The PM522 visually resembled a children's pistol from a science fiction movie, but at the same time the pistol had a strong and rigid frame. Washbear is also safer than its predecessors. At rest, the firing mechanism was not in line with the primer, so the PM522 was protected from accidental firing, for example, when dropped. The only metal part was the nail that replaced the striker. nine0006
Rifle
Grizzly
Canadian with the nickname CanadianGunNut, ThreeD Ukulele or simply Matthew, inspired by the Liberator project, designed and posted his project - Grizzly.
Grizzly is an ABS+ plastic rifle. It took the Canadian 3 days to design the rifle and another 27 hours to manufacture it using a Stratasys Dimension 1200es industrial 3D printer.
Grizzly 9 Rifle0244
The first version of the Grizzly had a smooth and straight .22 barrel. But this turned out to be not a very good decision, and the barrel cracked after the first shot. Subsequently, Matthew replaced the barrel with a tapered barrel with rifling inside.
Plastic “cutting” could not affect the ballistics of the bullet in any way, but added strength to the barrel.
Shotgun
Liberator 12k
The Liberator 12k is a 12-round shotgun made by a well-known, in narrow circles, enthusiast in the world of 3D printing - Jeff Rodriguez. nine0006
Liberator 12k
Rodriguez managed to create a simple and at the same time reliable design, "mixing" a pistol and a pump-action shotgun in the design of the Liberator 12k.
A huge plus for manufacturing and reliability was the absence of small parts in the shotgun mechanism.
Since the strength of the plastic was not enough, Rodriguez reinforced the design of the Liberator 12k with metal pins and added metal tubes inside the barrel and drum. The metal parts were purchased from a regular hardware store, so anyone could easily make a Liberator 12k with their home 3D printer. nine0006
Semi-automatic weapons
Shuty-MP1
The first sign was the Shuty-MP1, a semi-automatic pistol made by an amateur gunsmith with the nickname Derwood, in April 2017.
Shuty-MP1
Shuty AP-9
The Shuty AP-9 still uses a pistol barrel, but the trigger and return spring are taken from the civilian version of the M16. This improved the reliability of the rifle. nine0006
Ethical use
Despite the negative examples of application, 3D printing is actively used in many areas, helping to save time and create products that cannot be produced by other methods.
Medicine
Implants
Metal-printing 3D printers are actively used in medicine for the manufacture of titanium implants. For example, a patient needs to have a hip joint implant made. According to the results of CT, the necessary area of bone tissue replacement is agreed with the doctors and a prosthesis model is created that is ideal for this patient. After all approvals, the finished model is sent for printing. nine0006
3D model of implant
The main areas of 3D printing of implants in medicine are maxillofacial surgery, traumatology, orthopedics, oncology and veterinary medicine. A big advantage over classical methods of manufacturing implants is the ability to create a cellular or porous structure. This allows for better integration of the prosthesis into the bone tissue.
nine0243 Samples of printed implants and pins
Dentures
The manufacture of even a relatively simple traction prosthesis is a rather laborious and lengthy process.
3D printing has reduced costs and accelerated the production of prostheses. In addition, it became possible to customize the prosthesis.
Customized child prostheses
Some enthusiasts are modeling and posting models and detailed instructions for assembling traction prosthetic hands and fingers in the public domain so that any user can print and make a prosthesis at home. nine0006
Simple Traction Hand Model
Production
Building custom drones
Aerialtronics is a small Dutch company that specializes in building unique, customized drones. Aerialtronics manufactures and develops unique drones, the characteristics of which can vary depending on the needs of the customer. nine0006
Initially, a basic concept model was designed, which consists of a platform and a set of elements that can be changed at the request of the customer. Changes can affect almost any part of the drone.
The customer can choose the number of motors and their power, payload, flight time, supported software and much more.
Aerialtronics base model
But any, even minor changes in the characteristics and design of the drone required the manufacture of new elements and design changes. Classical manufacturing methods turned out to be quite laborious and long. To save time and money, a Stratasys uPrint SE Plus 3D printer was purchased. nine0006
Drone Assembly
Thanks to 3D printing, it was possible not only to speed up production, but also to devote more time to improving individual components, because the finished model is ready the next morning. Rapid manufacturing allows you to print a part, test it, make the necessary changes to the 3D model and make a new sample. Aerialtronics engineers manage to manufacture and test 8-10 variants of a part in a few days in order to achieve maximum quality. nine0006
Prototyping
Gas turbine prototyping.
Prototyping by traditional methods is often time-consuming and expensive. Because of this, the price of an error in calculations and 3D modeling can be very expensive.
For example, the production of turbine engine parts is usually based on careful preparatory calculations, but even this does not always prevent errors in the production of a test prototype. After all, even the most modern software methods cannot replace physical tests. But due to the high cost (over $20,000), it becomes impossible to produce multiple prototypes for testing. nine0006
Turbine Technologies (Wisconsin, USA) and its subsidiary Kutrieb Research have found a way out - 3D printing. Thanks to the 3D Systems ProJet 3D printer, it was possible to reduce the cost of prototyping by about 10 times to $2,000.
3D model and printed part of turbine
A turbine model is printed on a wax 3D printer, tested and then cast from metal. In addition to the cost, it was possible to significantly speed up production.
