3D printing for knifemakers


3D printing for knifemakers and in the world of knifemaking is something innovative and i’m experimenting with.

The ability to have more and more synthetic materials (TPU, PLA, ABS, HIPS, WOOD) and with various colors allows you to experiment with new solutions.

Attention!!! Experimenting does not mean selling knives with these elements assembled on the knife.

There are a few things I’m doing with the 3D printer and they are:

  1. Knife templates: Templates can be very useful for sharpening knives precisely. Make sure they are accurate and well-balanced for better results.
  2. Handle Pillows: Custom grip cheeks for knife handles or other utensils can greatly improve grip and aesthetics. Make sure they are ergonomic and comfortable to hold.
  3. Filled and perforated colored pins: Pins can be used to secure the handles of the cheek pads or other parts of a knife or other objects. You could experiment with different shapes and colors for a personal touch.
  4. Studies of knives in 1:1 scale: This is a very clever practice before making a full-size knife. You can run tests and observe how different parts integrate and work together without wasting expensive materials.
  5. Synthetic Guard: Guards are important for the safety and protection of hands when using knives. Make sure they are sturdy and well designed to fit the knife.
  6. Sharpeners: Custom sharpeners can be highly appreciated by knife enthusiasts. Make sure that the sharpening surface is smooth and of high quality.
  7. Miscellaneous: This category can include a wide range of objects. You can experiment with using the 3D printer to create specific supports, containers, or accessories for the knives and other tools you’re making.

Remember to use materials that suit your needs, such as PLA for decorative objects or ABS for more robust objects.

In addition, it is important to take the time to plan and design your 3D models accurately for optimal results.

What is 3D printing?

3D printing is the creation of three-dimensional objects using additive production, starting from a digital 3D model.

The digital or drawing model is produced with dedicated 3D software and then processed to be made with different technologies, including the one that builds prototypes layer by layer, through a 3D printer.

It’s a trial that I’m doing and that for my professional extraction is something simple.

I am completely autonomous in the realization of CAD with latest generation software (Catia/Unigraphics/SolidEdge/etc.) as well as having excellent knowledge about product development and prototypes.

3D printing is an advanced manufacturing process that allows you to create physical three-dimensional objects layer by layer, starting from a three-dimensional (3D) digital model.

This technology is also known as additive manufacturing, as it adds material layer by layer until the final object is obtained, unlike traditional material subtraction processes, such as metalworking or milling, which remove material from a block to create an object.

Here’s how the 3D printing process usually works:

  1. Creating the 3D model: To get started, you need to create a three-dimensional model of the object you want to print. This can be done using 3D modeling software or by 3D scanning an existing object.
  2. Slicing: The 3D model is then broken down into thin horizontal layers (often called “slices” or “sliced layers”) using slicing software. This process determines how the 3D printer will build the object layer by layer.
  3. 3D printing: The sliced file is then uploaded to the 3D printer. The printer uses one or more types of materials, such as plastic, metal, ceramic, or resins, to create the object layer by layer. Most 3D printers use a print head (often called a “hot end”) to deposit or harden the material layer by layer.
  4. Cooling or curing: Depending on the type of material used, a cooling or curing process may be required to harden the material layer by layer. For example, in Fused Deposition Modeling (FDM) printers, plastic solidifies through air cooling.
  5. Remove the finished object: Once printing is complete, the finished object can be removed from the 3D printer and, if necessary, post-process operations can be performed, such as removing print media or surface finishing.

3D printing has a wide range of applications, ranging from rapid prototyping to manufacturing, from the production of customized medical prosthetics to the creation of architectural models, custom jewelry, and much more.

It is an ever-evolving technology with the potential to revolutionize many different industries.

A brief introduction on the use of 3D printing in cutlery

In the world of knifemaking this type of technology is something still little used but very innovative.

Although I know that the pure of the knife could turn a little bit of a nose, i honestly don’t give a damn,it’s about experimentation,and no one should feel entitled to say what is right or not right to do.

Clearly as I anticipated it is to use this technology to make some parts, inserts, guards, dimes, etc. and then to use the printer to be able to create some parts or tools useful in the realization of the knife.

It is about making “a knife” and everyone lives it with the taste and passion that believes, there are those who are better, there are those who are less but no one should afford to block someone’s creativity.

A few years ago we did not use synthetic materials that are used with pride today and probably those who started using them were seen as not pure of knifemaking.

Experimentation is fundamental for the evolution of any craft field.

The knife community has a long tradition of craftsmanship and passion for detail, but that doesn’t mean it can’t adapt to new materials and new technologies.

The use of synthetic materials and 3D printing can bring significant advantages in terms of customization, precision and efficiency in knife production.

Creativity is a driving force in the making of handicrafts, and the fact that every knife maker can express their personal vision through new technologies is a good thing for the art and knife industry.

It is important to maintain an open and experimental attitude, constantly trying to improve and innovate.

History has shown that new techniques and materials can be viewed with skepticism at first, but can eventually become an integral part of traditional craftsmanship.

Keep exploring and doing what you’re passionate about, thus contributing to the evolution of cutlery.

The “eternal debate” between knife makers

Even today there is the debate between those who make knives with the tape sander (as I do) and those who use numerically controlled machines, such as the debate between those who use the forge and those who buy the steel bar already drawn.

Then between those who use the sander with a support top and those who freehand on wheel, etc.

Now my personal taste is to do everything on my own as much as possible but I repeat for my personal taste, from my micarta, to pins, mosaic pins, etc.

But I find that the real art is the design of the knife and the choice/matching of materials.

Then there is a fundamental quality that is the ability to realize, which I think is very important but to those who buy a knife I think they do not give a damn if it is made freehand, CNC, or other, it affects the design, the robustness, which cuts , and to do its job for the job it is intended for.

The custom author’s knife is different, where there is a real artistic research and materials, made with manic precision, where it is no longer a question of making a knife but an artistic object.

Ps. In fact, often seeing them I bow to the skill of the maker because they are real masters in making them but as knives are a shit, I explain better, they are works of art with the shape of the knife.

The debate among knifemakers about the choice of techniques and materials is a fascinating aspect of the cutlers community and reflects the diversity of approaches and philosophies within this art.

Each method has its advantages and charm, and in the end what matters is the final result and personal satisfaction of the knifemaker.

Here are some thoughts on some of the key points I want to highlight:

  1. Processing techniques: The use of the belt sander, CNC or freehand work with the forge are all valid knife manufacturing techniques. Each of them has its own nuances and advantages. The choice often depends on the personal preferences of the knifemaker and the end goal.
  2. Importance of design and materials: You are right to emphasize the importance of design and choice of materials. These aspects are fundamental for the creation of functional and aesthetically attractive knives. The design and selection of materials are key aspects of creating a successful knife.
  3. Customer satisfaction: When it comes to knives intended for use by buyers, functionality is often the most important aspect. Buyers look for knives that are well designed, sturdy, and perform their job well. The technique used to make them may be less relevant to them than the overall performance.
  4. Custom knives: These knives often represent the pinnacle of the knifemaker’s art. They are unique works of art, made with exceptional craftsmanship and often considered exhibition pieces rather than cutting tools. They are valued for their beauty and originality.

The variety of approaches in the world of knifemaking is what makes this art so fascinating and diverse.

Each knifemaker brings their own vision and creativity, helping to expand the boundaries of what is possible with a knife.

Whether it’s creating functional objects, artwork, or a combination of both, knifemaking is an art that embraces diversity and experimentation.
