New Currency Exchange Policy

At Bondtech, we aim to make great filament extrusion technology accessible, and as fairly priced for our customers worldwide as possible. Until recently, we simplified international pricing by using fixed exchange rates from USD — our base pricing currency — to EUR and SEK. For example, we set 1 USD = 1 EUR and 1 USD = 10 SEK, to keep prices structured and consistent worldwide.

We recently updated this policy.

Since the last few months, our shop calculates EUR and SEK prices based on the daily exchange rate instead of fixed ones. This change brings our prices closer to real market values and ensures more accurate, transparent pricing for everyone.

What this means for you

Because the USD has weakened compared to other major currencies, our products are now more affordable for many of our customers outside the US:

  • In EUR: Today’s exchange rate is 1 USD = 0.85 EUR, making our products around 15% less expensive than before.
  • In SEK: Today’s exchange rate is 1 USD = 9.38 SEK, lowering our SEK prices by more than 6%.
  • In GBP: Customers in the United Kingdom also benefit, as the USD to GBP rate has shifted in their favor, reducing purchasing costs compared to past levels. Same happens in Switzerland, Norway and Denmark.

A fairer and more flexible approach

With this new model, prices in EUR and SEK will continue to adjust with currency movements. That means prices may change over time, but they will always reflect the actual value of the currencies involved.

For now, and in the foreseeable future, this means lower prices for customers using EUR and SEK, but also lower costs for people using GBP, CHF, NOK and DKK.

In summary

  • Base net prices remain set in USD.
  • EUR and SEK net prices are lower and follow daily exchange rates.
  • GBP, CHF, NOK, DKK using customers pay less because the exchange rate is favorable.

We believe this change creates a fairer and more balanced shopping experience. It also helps more customers access the Bondtech tools they need to improve extrusion performance in their 3D printers.

Good Things Take Time

November 2024, we showed our OEM partners something that made them buzz: our very first manual tool changer prototype, INDX. It was bold, disruptive, and the response was enthusiastic. We got very excited.

March 2025, we pushed things even further by developing a whole new INDX tool changer, now with automatic swaps, a sleek design, and the first glimpse of a new era in tool changing (click here to see the video). But we knew it wasn’t yet at the uncompromising Bondtech standard for stability and precision. That’s why we set our launch date for November 2025, 8 months later.

Manual INDX : 1st development generation
Automatic INDX : 2nd development generation

September 2025, fast forward to now. Thank you for your patience! We’ve had many questions about the delivery, and now we can give you an update.

Our renewed INDX, currently 3rd generation, is in beta testing, and it’s something special. Built with a full aluminum extruder housing, it delivers incredible rigidity and repeatability like never before. It’s solid. It’s precise. It’s the foundation of what comes next.

Still, we decided to go further, harder and even stronger.

So we didn’t stop there. While the world is counting the months to launch, we are building yet another INDX — the 4th generation — this time aimed to be THE production-ready version that you don’t want to miss.

Visitors at FormNext 2025 will see the latest version live, applied, and running. Everyone will get the first chance to pre-order from our webshop, with deliveries starting late Q1 2026. As soon as possible, after we reach the final shape of the smart toolhead, we’ll start sharing simplified geometries to allow implementation projects to flourish.

So, on top of anything you know already about the INDX, what makes this latest version worth the wait?

  • Aluminum Chassis: A rugged structure delivering tool stance and handling rigidity.
  • + Positioning: Repeatable reference positioning system for the nozzle.
  • + Automatic Bed Probing: Automatic nozzle sensing for flawless bed leveling.
  • = Refined Precision: Every change, every move, every detail — carefully considered.
INDX : 3rd generation load/unload long term testing on test station

We know delays can be frustrating. But this isn’t just a delay — it’s a significant improvement, a major evolution, and a promise. When you finally get your hands on the Bondtech INDX tool changer, it won’t just meet your expectations. It will redefine them.

Why Extra Costs May Apply to Your Order

At Bondtech, we are committed to providing high-quality technology to customers around the world. Recently, however, some of our US customers have been surprised when contacted by carriers such as FedEx or UPS regarding additional costs due on delivery. We’d like to clarify why these costs arise and how the process works.

What Are US Import Tariffs?

When goods are imported into the United States from abroad, US Customs may apply tariffs (sometimes referred to as duties) on certain categories of products. These tariffs are set by US trade authorities and collected at the border, not by us as the manufacturer.
This means:

  • We do not add tariffs to your invoice.
  • Tariffs are determined by US customs regulations and collected upon entry into the country.
  • Products with different categories and countries of origin will incur different duty fees.
  • Your carrier (FedEx, UPS, etc.) acts as an intermediary: they clear your shipment through customs, pay the tariff on your behalf, and then invoice you for reimbursement before releasing your package.

How This Differs From VAT in the EU

Some customers confuse US tariffs with VAT (Value Added Tax) in the European Union. These are two very different systems:

  • EU VAT is a sales tax we must apply to all private customers inside the EU; to all Swedish companies; and to all non-VAT-registered companies outside Sweden but inside the EU. It is charged directly on our invoices and collected by us, then passed to the tax authorities. We do not invoice VAT to any private or corporate entities outside of the EU.
  • US tariffs are not a sales tax and do not appear on our invoices. They are import duties imposed by US customs on specific product categories, payable at the time of import.

Why Does This Matter?

When you order from us as a US customer, your total cost includes:

  • The product price (invoiced by us).
  • Shipping cost (invoiced by us).
  • The applicable US tariffs (invoiced by the carrier).
  • Small clearing customs service fee (invoiced by the carrier).

Our Commitment to Transparency

We make most Bondtech products ourselves in Sweden. US’ EU tariffs will apply. Some parts we use though, are not made by us and are mostly imported from China. These include all stepper motors; and most fans, heaters, and cables. These incur China tariffs when you buy them from us as separate spare parts or accessories.

We understand that unexpected costs are frustrating. Unfortunately, tariffs are outside our control, and neither we nor our shipping partners can waive them. Our role is to manufacture and deliver the technology you need; the role of customs is to apply the import regulations of the United States.

We remain committed to helping our US customers navigate this process as smoothly as possible. If you have questions about tariffs or customs clearance, your carrier (FedEx, UPS, etc.) can provide detailed information specific to your order.

What IN means, in Bondtech INDX

INDX is a novel solution for tool changer systems composed of a single smart tool head serving a limitless amount of thin passive tools.

Multi-color, multi-material, and multi-nozzle applications found the smartest solution available, and we believe it will influence the whole filament 3D printing market from now on.

Visit the INDX info page

Two weeks ago we revealed what DX in INDX means. The Dynamic eXtruder is reactive, it self-adjusts to filament type, volumetric flow and other printing conditions. It sets the proper filament pre-tension on its own.

The DX is based on our latest patent pending, filament feeding technology, now named Dynamic Dual Drive.

Today though, we are here to talk about the IN in INDX

How did we arrive here

There is a little parallel story behind how we got here. Let me share it with you.

Over 3 years ago, working as Product Manager at Bondtech, I started asking our Engineers, and to Engineers at our Partners, a very convoluted question:

Why do we heat-up a wire, to heat-up a cement, to heat-up a capsule, to heat-up a heat-block, to heat-up a nozzle, to melt plastic?”

Eyebrows were raised all the time, even though… it is pretty convoluted, right? The process in itself, not just the question. Everyone agreed. A new way was necessary. Could we heat up the nozzle directly?

We needed some resources to investigate that.

We ordered some sets of Mini Induction Coil Heaters. Distributed a couple over our Engineers and did a steel bar heating-up measurement.

While testing, that mini heater could raise the temperature of a massive 12mm diameter steel bar, up to way over 200C in less than 15 seconds.

Impressive, but long way from being a product. Knowing about induction heating doesn’t make it a ready-to-use solution for our customers. We knew it would take vast time and resources we didn’t have at the time. Matter adjourned.

The story resumed about one year later to the likes of so many others…

“An inventor knocked on our door to present us some breakthrough ideas.”

It was a collection of ideas bundled into patent submissions and a raw but practical demo. One working freaking demo! All together just brilliant. Among other raw and ready-to-use concepts, one idea stood out and brought back old thoughts — the core idea behind the IN in INDX.

IN is for INduction

Super Fast heating with INduction

Electromagnetic forces are used to heat up the INDX nozzles in a few seconds, using low power. The novel approach of combining the effect with the low thermal mass of the nozzles was key for the blazing fast performance.

How does it work? An INduction coil directly and rapidly increases the temperature of the nozzle by using electromagnetic induction that creates eddy currents to generate heat within its material.

Basicaly the wheel re-invented. Not totaly new, but never used this way either. Almost a direct energy-to-plastic transmission. No convoluted steps in between. Pure efficiency.

From those starting ideas much has evolved in the last 2 years. At Bondtech we took it to another level and put much work on industrial design, reliability, safety, fine tunning and application.

It took us that much to get here, and the path is far from ending. The INDX is still in a state of flux. The geometries are not frozen. Much feedback is being received from our community of makers and creators.

As a proof of concept, we believe the INDX earned its stripes already, but work continues.
We also need your creativity and ingenuity to implement the INDX the best we can. Drop on us some (good : ) ideas here.

Thank you.

What DX means, in Bondtech INDX







INDX is a novel solution for tool changer systems composed of a single smart tool head serving a limitless amount of thin passive tools.

Multi-color, multi-material, and multi-nozzle applications found the smartest solution available, and we believe it will influence the whole filament 3D printing market from now on.






16th of March 2025,
a date for the 3D Printing History books. Bondtech unveils over two years of research&development in the shape of a video portraying the Bondtech INDX.

The reaction was huge. INDX was very well received, and of course hundreds of questions were asked.

Some have already been answered here. Today we want to begin answering what INDX means. The DX half first.



The Filament Feeders Pre-Tension Management Evolution



Since the QR extruder Bondtech reveiled a better way to manage the filament pre-tension, a critical setting to ensure reliable extrusion. The Quick Release flexible hinge and spring loaded thumbscrew was a first and was later adopted by nearly everyone in the filament 3D printing space.


Later, with the LGX Large Gears eXtruder Bondtech created a novel approach to allow a cam enabled LGX lever to define filament pre-tension in discrete steps to ensure reliable and repeatable results. The red capped lever was a success. Users all over the world welcomed this easy to use feature. In a simple and objective way, we could select the right pre-tension setting to the type of filament in use.

Now, Bondtech created something entirely new once again.




DX Is For Dynamic eXtruder










What is a Dynamic eXtruder

Building on previous innovation, Bondtech now presents the ultimate easy-to-use pre-tension setter. No user intervention, skill or action required.

The INDX uses a new and clever dynamic dual driving technology. The dynamic extruder reacts on its own, and self-adjusts, to the optimal pre-tension required to print any material, at any requested volumetric flow, and under any 3D printing conditions.




What else is the Dynamic eXtruder doing

This novel dynamic approach is also what allows for the large dual drive gears to mechanicaly open wider and close tight so the filament can be both front on/off loaded and fed.

the INDX‘s gearbox, engineered by the Bondtech team, uses one single light and powerful stepper motor (also used on the LGX Lite Pro) to drive the filament and to engage the thin passive tools.

The result? Reduced weight and minimal multi-tool complexity achieved.








NOTE: Because the Dynamic eXtruder is a patent pending technology, additional mechanical and structural details will only be disclosed at a later time.

Unleashing Core Heating Technology (CHT) in 3D Printing: A Game-Changer for All Scales

In the ever-evolving landscape of 3D printing technology, a groundbreaking innovation has emerged that promises to revolutionize the way thermoplastic filaments are melted and deposited. Known as Core Heating Technology (CHT), this advancement, pioneered by visionary inventor Carl Beck and championed by Bondtech, offers a transformative solution for enhancing the speed, efficiency, and quality of 3D printing processes across a wide range of applications.


The Origins Story

The journey of Core Heating Technology began in late 2016 when Carl Beck, a trailblazing inventor, introduced a series of brass nozzles for filament 3D printers under the moniker “Matchless.” These innovative nozzles featured multiple orifices for filament entry, optimizing the contact surface of the hot metal with the plastic. Beck’s relentless pursuit of innovation led to the development of Core Heating Technology, aimed at maximizing the melting capacity and performance of 3D printing systems.

In 2017, Beck applied for a patent (EP3445568A1) to protect his groundbreaking technology. This patent encompasses a 3D printer and method designed to increase printing speed by incorporating generic geometric features on a heating block, nozzle, and heat-conductive material for efficient heat transfer. Subsequent developments led to the extension of intellectual property protection to the United States (patent EP3445568A1), reinforcing Beck’s commitment to safeguarding his innovative contributions.

Recognizing the immense potential of Core Heating Technology, Bondtech, a leading player in the 3D printing industry, forged a strategic partnership with Carl Beck to integrate CHT into its product portfolio.
