What materials are used for printing the prototypes?

The materials depend on the machine and technology, as well as the purpose you need the end product. The most commonly used materials according to this technology are:

–  FDM technology – ABS material

– SLS technology – PA material

–  SLA technology – photopolymer material.


How is the price calculated and how long will I wait for you to give me an offer?

The pricing is based on the amount of material that will be needed to make the part or the object. Depending on the technology, it might be measured in cubic centimeters (cm3) or milliliters (ml). You can see the approximate prices per unit volume here. The volume calculation includes all supporting structures required to create the product. We will make our best to offer you the best price!

Is there a minimum quantity or order value?

At Solid Fill, we have a minimum order value of 30 lv (excluding VAT). Within this amount, we can produce as many units as possible of the desired element or product.


How long does it take from the request to the receiving of the prototype?

We aim to be as quick as possible, and our goal is to send your prototype within a maximum of 3 business days. However, the time frame depends on several factors: errors in the digital model that our engineers must repair; size, amount, complexity, the workload of our machines at the current moment and of course, your specific requirements. The actual time for completing your project will be included in the offer you will receive.


I do not have a 3D model, but I have drawings, sketches, and ideas I wish to realize – is it possible to make something out of it?

Yes! Even if you need to start from scratch, our designers are ready to help you with making a 3D model even if you only have an idea in your head! We can create a 3D model from drawings, sketches, pictures, etc., as well as to make a replica of a completed part, taking its dimensions through 3D scanning and modeling

Here you can find thousands of free and ready-to-print 3D models:  http://thingiverse.com


What file formats do you support?

We work with all formats used on the market. Trying to make it as easy as possible for you, we accept each of the following popular formats and convert it free of charge:


Of course, if there is a problem with the conversion, or if we find a potential problem, we will contact you immediately.


Will you fix any problem in my 3D model if it is necessary?

Yes! Free of charge we will check and fix the problems in your 3D model if needed. If the errors are too complicated or require a change in the model itself, we will immediately contact you.


What are the recommended modeling practices?

Here, you can download several documents describing the minimum requirements and best practices in order for a model to be printed using any of the technologies available: https://solidfill.com/resources


How will I get my prototype after it has been completed?

Your project details will be sent via your preferred shipping company (e.g., Econt, Speedy, DHL, UPS, etc.) at your own expense. Of course, you can also personally get the details from our office in Sofia at 84 Kumata Street (Boyana Cinema Center).


What are the options for paying for your services?

We will accept the most convenient payment method for you – cash on delivery, bank transfer, PayPal, ePay, etc. If you need an invoice, it is a good idea to send your billing information in advance.
