I'm not getting paid at all. They refuse ANY payout, with a conveniently persistent error message that has been showing up for months.
And when I try to contact support through their platform about the issue, I get yet another convenient little error message telling me that my support ticket could not be sent due to an "internal server error."
Absolute scam.

I lost everything
The page randomly refreshes and all my hours of work on color filaments and settings for my printer were lost and I recommend nobody to use Treatstock

pure scam
That printer service under Treatstock is a total rip-off. You print something exactly as it's supposed to be, but then a customer dislikes the results because they wanted a different orientation without saying anything or orienting the file that way. They get a full refund, and you're stuck printing for free.
After asking politely why I'm the one who needs to deal with that, the original answer from support was: "Hello, customer disliked result before shipping. Cheaper do refund."
It's just an unprofessional rip-off. Not to mention that it can take months to pay you out.

We would recommend focusing on real orders. We received negative feedback about small losses of a few dollars on the manufacturer's and our sides due to a decision made in the user's best interests.

One year later: Treatstock still hasn't paid us
It has now been more than a year since Treatstock failed to pay out earnings for completed 3D printing orders, and despite dozens of attempts to reach them through the platform, email, and phone, we have received zero response.
We fulfilled our end of the agreement: the clients were satisfied, the work was completed on time, and Treatstock received payment for it. Yet our payout request has simply been ignored for over a year, with no explanation, no acknowledgment, and no resolution.
This isn't a one-time delay or a misunderstanding — it's sustained, total silence from a company holding funds that belong to us. We are formally asking Treatstock, once again, to resolve this and release the payment owed to us.
To any other service providers considering partnering with Treatstock: think carefully. If reliable, transparent payouts matter to your business, our experience suggests you cannot count on that here.

Manufacturers with reliable information and documents do not have problems.
Please contact us through the platform by messaging the Support Team. We will investigate your case if it has not been resolved yet. If it has already been resolved, we apologize for any inconvenience.

Er hat keinen bekommen d.h. Hier wird jeder Verlauf zwischen Kunde und Händler kontrolliert. Einfach schlecht

Hallo,
wir verstehen Ihren Frust, möchten aber einige Punkte klarstellen. Ihr Konto wurde nicht ohne Grund eingeschränkt. Unser System hat einen Verstoß gegen die Nutzungsbedingungen festgestellt, nachdem im Zusammenhang mit einem Auftrag Kontaktdaten bzw. externe Kommunikationswege geteilt werden sollten. Dies dient dem Schutz aller Nutzer und der Sicherheit der Plattform.
Außerdem möchten wir darauf hinweisen, dass die Sichtbarkeit und Anzahl der Anfragen stark davon abhängen, wie aktiv ein Profil gepflegt wird und ob zusätzliche Promotion oder Werbung genutzt wird. In Ihrem Fall wurde der vermittelte Auftrag von Ihnen selbst storniert und unmittelbar danach versucht, Kontaktdaten außerhalb der Plattform zu teilen. Dies stellt einen klaren Verstoß gegen unsere Bedingungen dar.
Wenn Sie Fragen zur Einschränkung Ihres Kontos haben, kontaktieren Sie bitte direkt unseren Support – wir helfen gerne weiter.

Very poor service compared to what I…
Very poor service compared to what I expected. It was only an eleven euro order, and they gave me trouble because I wanted a very small size, which was impossible to make, even though it was a top manufacturer. In the end, I had to cancel the order. I don't recommend them.
Response from TreatstockMay 8, 2026
Thank you for your feedback. We’re sorry the experience didn’t meet your expectations. Producing very small custom parts can be technically challenging, especially at prototype scale, and in this case the manufacturer determined that the requested dimensions were not feasible within the scope of an €11 order. Rather than delivering a result that might not meet quality standards, the order was cancelled. We understand the frustration and appreciate your understanding.

Useless customer service / Service client nul.
Dispute closed, final review:
how silly of you to invoke french law against me when you don't respect it either.
After nearly 30 days of zero response from the manufacturer, yes i contacted the him on his social media, i send him two (2) messages, that could hardly be called harassment.
And you know what ? I think it was the right thing to do because he finally responded and told me something usefull : He already told you to cancel the order and proceed to full refund.
The thing is, you did not follow what he told you to do, instead you were searching for the smallest meaningless thing to not refund me !
- I was promised a tracking number, never got it.
- I asked for a refund under Article L216-2 of the french consumer right law, you didn't care.
- You pretended to have a proof of receipt, i asked for it, never got it.
- You even send me what looks like a counterfeit proof of deposit, untracked shipment cannot have a proof of deposit.
- You told me to check with postal service about the package, under French and European consumer right law the vendor has full responsibility over the package so it was not my job to do that but his/yours, i still did it, French postal service told me what we already know : Untracked shipment cannot be traced.
In the end, manufacturer acknowledged your incompetence and refunded me from his own pocket, not you.
From start to finish, you didn't care about customer.
Litige terminé, avis final:
C'est surprenant de votre part d'invoquer la loi française contre moi alors que vous ne la respectez pas non plus.
Après presque 30 jours sans réponse de sa part, j'ai effectivement contacté le fabricant sur ses réseaux sociaux et lui ai envoyé deux (2) messages, ce qui ne saurait être qualifié de harcèlement.
Et vous savez quoi ? Je pense que j'ai bien fait, car il a fini par répondre et m'a donné une information importante : Il vous avait demandé d'annuler la commande et de procéder à un remboursement intégral.
Le problème, c'est que vous n'avez pas suivi ses instructions, au lieu de cela, vous avez cherché le moindre prétexte pour ne pas me rembourser !
- On m'as promis un numéro de suivi, jamais reçu.
- J'ai demandé un remboursement en vertu de l'article L216-2 de la loi française sur la protection des consommateurs, vous n'avez rien fait.
- Vous avez prétendu avoir une preuve de réception, que j'ai demandée, jamais reçue.
- Vous m'avez même envoyé ce qui ressemble à une fausse preuve de dépôt, un envoi sans numéro de suivi ne peut avoir de preuve de dépôt.
- Vous m'avez demandé de me renseigner auprès des services postaux concernant le colis, or selon la législation française et européenne sur la protection des consommateurs, le vendeur est entièrement responsable du colis. Il ne m'incombait donc pas de le faire, mais à lui/à vous. Je l'ai néanmoins fait et Les services postaux français m'ont confirmé ce que nous savons déjà : un envoi non suivi est non traçable.
Finalement, le fabricant a reconnu votre incompétence et m'a remboursé de sa poche, pas vous.
Du début à la fin, la satisfaction client n'étais pas votre priorité.

NOTICE! This individual has been observed engaging in behavior that may fall under Article 222-33-2-2 of the French Penal Code, which criminalizes repeated harassment and stalking, including through digital communications.
We hope that Trustpilot will retain this review so that other services can be aware of the risk, understand how to respond, and, in the event of recurrence, be able to contact the authorities.
The refund will not be processed instantly in response to the customer's request. First of all, we should find out what happened from both sides. Sorry for the inconvenience.
Update: The prototyping of a low-cost model was completed, and the manufacturer shipped the product.
After the customer claimed that the first parcel had not been received, the manufacturer sent a second one as a goodwill gesture.
The manufacturer later provided an official document from the postal service confirming that the first parcel was in fact received by the customer. Based on this confirmation, the manufacturer has declined to send a third unit.
Despite this situation, the customer continues to receive full support. The manufacturer made a refund.

Terrible customer service
Terrible customer service, Terrible platform. Tax forms don't work, customer service doesn't respond, they're unhelpful and a waste of time. Not worth the hassle as they don't have their platform working correctly. Find alternatives and don't waste your time.
