This Privacy Policy explains how information is handled when visitors use 3dprinting.directory, browse supplier listings, read articles, or contact the website.
3dprinting.directory is an independently maintained, currently noncommercial directory of 3D printing and additive manufacturing suppliers serving metal casting and foundry applications.
The website publishes information about industrial suppliers, their publicly advertised products and services, and related manufacturing technologies.
The directory is operated independently by an individual based in the European Union. It does not currently offer paid listings, visitor accounts, or online purchases.
For privacy enquiries, questions about personal information, or requests to correct directory listings, please contact:
Email: info@3dprinting.directory
We aim to limit personal data processing to what is reasonably necessary to operate the website and respond to enquiries.
When someone visits the website, the website platform and its technical service providers may process information such as IP addresses, browser and device information, pages requested, access times, and technical diagnostic information.
This information may be used to deliver the website, maintain its performance, troubleshoot problems, and protect against misuse.
If you contact info@3dprinting.directory, we receive your email address, the information contained in your message, and any additional details you choose to provide.
We use this information to respond to enquiries, handle requests concerning supplier listings, and manage related correspondence.
Directory listings primarily contain business information, including company names, websites, descriptions of products and services, and relevant technical classifications.
Information is obtained from publicly available company websites, published business materials, and other relevant sources.
Some business information may also qualify as personal data, particularly where it identifies a sole trader or an individual business contact.
We aim to publish only information relevant to the directory's industrial supplier-discovery purpose.
Requests to correct or remove personal information from a listing can be sent to info@3dprinting.directory.
Where the General Data Protection Regulation (GDPR) applies, we rely on the following legal bases as appropriate:
Visitors do not need to provide their name or email address simply to browse the directory or read its articles.
We use third-party services to publish and operate the website.
3dprinting.directory uses a third-party website hosting and publishing platform to deliver its pages and services.
The platform and its technical service providers may process information such as IP addresses, browser information, and technical logs where necessary for website delivery, security, and maintenance.
Supplier listings are supplied to the directory through a publicly published Google Sheets data feed.
This feed contains information intended for public display, such as supplier names, websites, descriptions, and classifications.
Information published through the feed may also be accessible directly through its public spreadsheet address.
Private supplier research notes and correspondence are maintained separately from the public directory feed.
Google's privacy practices are described in the Google Privacy Policy.
Messages sent to info@3dprinting.directory are processed by the email service used to receive, store, and deliver correspondence.
Relevant information may also be processed by technical service providers where necessary to operate the website or respond to enquiries.
We do not sell visitors' personal information.
Cookies and similar technologies may be used by the website platform or its service providers to support website delivery, functionality, reliability, and security.
We have not independently configured advertising tracking or separate analytics scripts through the website's global custom HTML settings.
This does not mean that the underlying website platform uses no cookies or other technical technologies.
Where applicable law requires consent for non-essential cookies or similar technologies, the relevant information and consent controls must be provided before those technologies are used.
Visitors can also manage or block cookies through their browser settings. Some website functions may be affected if necessary cookies are blocked.
The directory contains links to supplier websites and other external sources.
When you follow one of these links, you leave 3dprinting.directory and may become subject to the destination website's privacy practices.
We do not control how independently operated external websites collect or process personal information.
We aim to retain personal information only for as long as reasonably necessary for the purpose for which it was processed, subject to any applicable legal requirements.
Email correspondence is retained while an enquiry or related matter is being handled and, where appropriate, afterward for administrative, record-keeping, or legal purposes.
Supplier information may remain published while the listing is relevant to the directory. Information may be reviewed, corrected, or removed when appropriate.
Technical logs and related information are subject to the operational requirements and retention practices of the relevant infrastructure providers.
Some technology and email service providers may process information outside the European Economic Area, depending on their infrastructure and service arrangements.
Where GDPR restrictions apply to international transfers of personal data, those transfers must be supported by an appropriate legal mechanism, such as an adequacy decision or applicable safeguards.
For questions about the processing of information through this website, please contact info@3dprinting.directory. Information about individual providers' processing practices is also available in their published privacy notices.
Where the GDPR applies, individuals may have the right to:
To make a request concerning personal information, please email info@3dprinting.directory.
You also have the right to lodge a complaint with a competent data protection supervisory authority.
Information about EU data protection authorities is available from the European Data Protection Board.
The website does not currently use automated decision-making that produces legal or similarly significant effects concerning its visitors.
This Privacy Policy may be updated to reflect changes in the website, its services, data-processing activities, or applicable legal requirements.
The date shown at the beginning of the policy will be updated when the policy changes materially.
