FAQ

What are configurable mechanical components?

Configurable components are products in which you can select specific design features, and see the price and delivery times at a glance.

The most used configurators include linear shafts, linear guides, miniature linear guides, aluminum extrusions and aluminum sheets. Select your specifications from material, surface treatment, length and diameter.

Tailor-made processing

Our “DHM projects” tool allows you to save different projects or lists of articles on our website and sort them when it suits you. You can easily add them to your cart by clicking the "Add Project to Cart" button, or you can quickly edit them by removing and adding products from any device by logging into your account.

You can also share projects in various ways. You can submit a read-only copy and the person you shared the project with can order directly on our website. For more details, go to your projects and click the “Share Project” link.

Alternatively, you can export the project to PDF or CSV so that you can always consult, even offline, the detailed list of products of your project.

It is also possible to make your project public on the dedicated page of our site, so that everyone can take inspiration for automation applications, 3D printing, IoT ...

A single point to find insights, application tips, videos, technical articles and tutorials, but not only, to support you during the development of your projects.

Thanks to the advanced search, browsing the categories and products of the DHM-online site is much easier. In fact, the advanced search allows you to search through filters by restricting the number of compatible components to your needs until you find what you were looking for.

The product comparison tool allows you to select up to 3 products at a time to compare. On the dedicated page you can compare the information and specifications of the selected products in a side-by-side format, simplifying the identification of similarities and differences between products.

Items can be easily removed or added to the cart by clicking on the appropriate button. Find out more

Nous avons rendu encore plus facile la vérification de la disponibilité des stocks et des prix, ainsi que l'achat de produits.

Sur chaque page produit, comme dans le panier avant de conclure la commande, vous pouvez vérifier l'inventaire en temps réel de l'article, avec le timing du matériel et les détails spécifiques concernant le traitement, le cas échéant.

Sont également indiqués les stocks pouvant être achetés en rupture de stock avec les délais relatifs aux arrivages et à la gestion par l'usine de fabrication.

DHM now offers you the option to save and share your cart. This way you can save the products for a future order, or forward your shopping cart to a colleague to place the order. You can also save multiple carts. For all the details, log into your cart and click on the "Share" or "Save" icon. You must be logged in to your account to be able to save your carts.

From the page dedicated to quick orders, you can quickly proceed with the order of all the products you need at once.

Just enter the store product code (reference - SKU), title, variant and quantity required. Click on "add to cart" and you will be ready to complete the purchase.

Alternatively, you can upload the product list (BOM): upload an Excel, CSV or tab-delimited file, with the title or product code and the desired quantity. You will find the example file on the dedicated page.

Extruder group - 3D printing

Extruder Assembly

Compass DHM projects stocks a wide assortment of parts and upgrades for 3D printers.
A category dedicated to extruder assembly parts and upgrades for FDM 3D printers.

Even changing a simple nozzle on your 3D printer can instantly expand the variety of 3D filaments you can print with. A better hotend can lead to higher print quality, as well as allow for higher temperature prints. All that's left is your choice!

In this section you can find:

Extruders - Extruders
Melters - Hot end
Nozzles
Accessories

The extruder unit is the heart of a filament 3D printer (FDM). In fact, it is the part of the machine that melts the filament and deposits it on the print bed. An extruder assembly consists of the following components:

Extruder: the actual extruder, responsible for how much and how fast the 3D printer pushes the filament into thehotend.
Hot end is the component of a 3D printer that melts the filament for extrusion and maintains a consistent and accurate temperature to ensure print quality. A hotend that reaches higher temperatures means that a wider range of materials can be printed, such as nylon 3D printing filament, polycarbonate 3D printing filament, or PEEK.
Nozzle: Also called a nozzle, this is the component of a 3D printer that deposits molten filament into the printing area. There are many types of 3D printer nozzles available, each with its own strengths.
