Engineering studio in Groningen · Software · Automation · 3D printing
OmniTechs is Sina Esfahani's small engineering studio in Groningen. We build websites, automation and custom software, and make plastic 3D prints and testable prototypes. Every project starts with the function: what must work in practice?
Choose a direction below to see what to send, how we assess it and where to go next. Scope and price are agreed in writing before work begins.
Ask usSERVICE INTRODUCTION / 01
Send your file, dimensions, quantity and intended use. We check feasibility, discuss material and finish, and quote before printing.
SERVICE INTRODUCTION / 02
Tell us what the prototype must prove, which dimensions are fixed and what is still uncertain. We discuss a first buildable version and what to change after testing.
SERVICE INTRODUCTION / 03
Share the part's dimensions, load and operating conditions. We discuss whether a 3D print fits and which tolerances or test fits matter.
SERVICE INTRODUCTION / 04
A sketch, photo and dimensions help us assess the design task. We agree on the model you need and how to review it before production.
SERVICE INTRODUCTION / 05
Show us the object and the accuracy you need. We first assess whether scanning can produce useful geometry and what modelling or test print is still needed.
HOW THE ROUTE WORKS
SERVICE INTRODUCTION / 06
Size, material, print time, finish and quantity affect the quote. Review the cost factors, then send your file for a price based on your request.
SERVICE INTRODUCTION / 01
For independent professionals and small businesses: start with what visitors need to understand and do. Scope, supplied content and fixed package price are agreed in advance.
SERVICE INTRODUCTION / 02
We map the handoff, check your existing tools first and keep human review where a decision matters. The initial conversation is free; discovery and implementation have separate scopes.
SERVICE INTRODUCTION / 03
A defined function, user and data flow make custom work assessable. We review existing options first, then agree design, implementation and cost separately.
SERVICE INTRODUCTION / 04
For example, a request, a status view or an internal action. We define access, required data and what the first version must do.
SERVICE INTRODUCTION / 05
We map which data moves when, who owns it and what happens on failure. Then we assess whether an existing connector is enough or custom work is needed.
HOW THE ROUTE WORKS
SERVICE INTRODUCTION / 06
A QR code or NFC tag can open a focused link page, contact action or review request. We match the destination and physical format to its use.
In our customers' words
“I printed three large architectural designs with this company and was truly impressed. The quality and service were outstanding. I just sent them my 3D model, and they took care of everything, keeping me updated throughout the process. Even when I reached out late at night, they responded right away. The delivery service was also a great bonus!”
Ayman had three large architectural designs 3D printed with us. This is his public Trustpilot review.

Public Trustpilot review of the OmniTechs experience (not product-specific).
Read Gert's full review“Ik wist zelf eigenlijk niet veel van 3D-printen en had vooral een idee van wat ik wilde. Sina luisterde goed naar mijn wensen en liet me vervolgens verschillende mogelijkheden zien. Hij nam echt de tijd en stuurde meerdere modellen door totdat we iets vonden waar ik echt enthousiast over was.
Wat ik vooral fijn vond, is dat ik zelf niet alle technische keuzes hoefde te maken. Ik kon gewoon uitleggen wat ik mooi vond en wat ik nodig had, en Sina hielp me om daar de juiste optie bij te vinden.
Na deze ervaring weet ik eigenlijk al: als ik in de toekomst iets wil laten maken of 3D-printen, ga ik gewoon direct naar Sina.”

Read Karim's review on Trustpilot“Έψαχνα κάτι πολύ συγκεκριμένο, το οποίο δεν μπορούσα να αγοράσω πουθενά, οπότε στράφηκα στο 3D printing. Είχα αρχίσει να πιστεύω ότι δεν πρόκειται να το αποκτήσω, καθως κάθε φορά που έπαιρνα στα χέρια μου κάποιο αποτέλεσμα, η ποιότητα δεν ήταν καλή και η τιμή υπερβολικά υψηλή. Ευτυχώς έπεσα πάνω στην ιστοσελίδα του Sina, και μεσα σε 3 μέρες είχα επιτέλους ένα προϊόν όπως το ήθελα, σε καταπληκτική ποιότητα και με προσιτή τιμή! Τον συστήνω ανεπιφύλακτα!”
