Why 3D Print
-
3D printing enables fast and efficient production of both simple and complex geometries while not requiring expensive moulds, tools or machining blanks. This allows to manufacture parts in fraction of regular leadtime for machined parts.
Also, producing small and medium series using 3D printing is often more offective than machining from blanks or using plastic injection.
- Typical casesin which 3D printing is the optimal manufacturing method are:
- Large parts for machining with high amount of material removal
- Cases or cabinets for electronic components
- Parts that are very difficult to or cannot be produced by machining.
- Medium production runs where tooling costs are substantial
Why Alter3D
Expertise
- Top production machines are not enough! Alter3D combines engineering know-how, problem insight and innovative approach.
Quality
- We don't just print 3D data - we deliver products that match the dimensions of the original and fullfill function..
Pushing the boundaries
- We are happy to print simple parts for you! However, our goal is to push boundaries and offer effective solutions where it previously wasn't thought possible.
Services
3D Printing service
- Single part to medium production series – we will choose appropriate printing parameters according to your needs, recommend suitable materials, and print your parts. Using FDM printers with a heated print chamber, we can print both standard and engineering materials."
3D data creation and editing
- Do you only have a part, drawing or different documentation? Never mind! We will create 3D data without a problem. We can also modify an existing 3D model to suit your requirements.
Complex orders
- We exceed expectations by combining 3D scanning, printing and digital modelling. We choose the most appropriate process for each project, including post-processing of printed parts. Our years of experience and in-depth knowledge allow us to offer tailor-made solutions for even the most demanding requirements.
Engineering projects
- We combine knowledge of mechanics, materials, electronics, and pneumatic circuits into the expertise needed for development and creation of technical documentation for single-purpose machines, fixtures, or other components and assemblies. Do you have an idea or concept but lack the development capacity? Contact us!

Frequently asked questions
Production and materials
How precise is our printing?
Unfortunately, several concepts are often confused with the term accuracy:
• The smallest possible manufacturable geometry on a part is resolution. It is not related to manufacturing precision. The resolution ranges from 0.1 - 0.4 mm depending on other conditions on our machines.
• Repeatibility refers to the dimensional deviations between multiple finished parts. Depending on the size of the print, our repeatability can be within hundredths of a millimeter.
• Accuracy is dimensional deviation of product from documentation.
We usually achieve production accuracy according to the table below (inspired by DIN 16742 – Plastics moulded parts - Tolerances and acceptance conditions – TG4-NW).
| Nominal dimension [mm] | < 30 | > 30 – 80 | > 80 – 120 | > 120 – 180 | > 180 – 250 | > 250 – 315 | > 315 – 400 |
| Dimension tolerance [mm] | ± 0.10 | ± 0.20 | ± 0.30 | ± 0.35 | ± 0.41 | ± 0.45 | ± 0.63 |
Our prints are often more accurate depending on the material and shape. For individual tolerance assessment specify your precision requirements in the inquiry form and we will evaluate feasibility options.
Individual agreement with prints tuned to high degree of precision is naturally possible as well.
What is toughness?
Toughness refers to a material's resistance to the initiation of fracture. An example of a material with high toughness is rubber, which can deform significantly before breaking. In contrast, brittle materials, such as glass, fracture with minimal deformation."
What is material strength?
Strength is the ability of the material to carry mechanical load. A print made of a stronger material has a higher yield/tensile strength and can therefore carry a higher mechanical load.
What is rigidity?
Rigidity refers to the degree of deformation in response to a load. If two materials have the same strength, but one has significantly higher stiffness, both will withstand a similar load before failure. However, the stiffer material deforms much less before reaching its breaking point.
What is heat resistance?
This is a much more complex issue. It’s important to keep in mind that the mechanical properties of plastics gradually decrease beyond a certain temperature until they eventually melt. The maximum temperature is defined as a point where this reduction in properties exceeds an arbitrary threshold—specifically, where a certain deformation is surpassed under a constant load. Some manufacturers provide two heat resistance values: a higher one for short-term exposure (lasting minutes) and a lower one for long-term exposure to elevated temperatures. Generally, once the maximum temperature is exceeded, the product can no longer function properly. However, this limit should not be regarded as an absolute value.

How will the pricing and production process proceed?
After submitting a non-binding inquiry with information and model, we will send back price offer for requested quantity of parts, estimated delivery date and any questions for clarification or conditions of production. After your decision, you will let us know you want to place a binding order and we can start printing.
What has to be included in the inquiry form?
For a standard 3D print service request, please provide as much of the following information as possible:
• 3D data in STL, STEP or other universal file format
• number of requested parts
• material
• color
• preferred term of delivery
• any further specification requirements
For other types of inquiry, please provide as much relevant information as possible.
How much will it cost to 3D print my parts?
Unfortunately, there is no universal answer. Machine hours are not relevant here, the same job can be produced with different printers in very different times in the same quality level. Please send us a non-binding inquiry and we will price the production for you.
How long will the production process take?
For urgent orders with a corresponding scope, the order can be shipped as early as the next day. Orders with volumes up to higher tens of production hours, the delivery time is usually 3-6 work days. For large, complex, or recurring orders, the delivery date will be scheduled by appointment. The delivery time will be specified in the offer at the time of ordering.
How will the parts be shipped and paid for?
We offer dispatch by Zásilkovna and Česká pošta for 100 Kč. Alternatively - we'll gladly schedule personal handover in Brno with no additional costs.
For private individuals, payments can be made through advance invoices, cash on delivery, or immediate payment by cash or transfer upon personal delivery.
For freelancers, independent contractors and companies, payments may also be made via invoice with a 30-day payment term.
