PITTA

PITTA Launching

The PITTA_Multi-Color Module is priced at 399 USD and includes PITTA Base (339 USD) + Adaptation Kit (60 USD).

Shipping started in January 2022.

PITTA is only applicable Ender3 V2, Ender3 pro 32bit(4.2.2 or 4.2.7 main board used, SKR2.0 for Ender3 pro) and CR6 SE.

We are working for another, but not finished, so be careful to get PITTA.

Becasuse of logistics(cost and delivery), available shipping country is not enough at first. 

If your country is not included in the list, mail us(pitta.3dprinting@gmail.com), we will add those first. 

Plan to expand the model using PITTA

1. Direct support will continue by selecting models with a large user base. (ex, CR6 SE etc)

2. In the case of a specific model, there are difficulties in support because the user base is not thick or the composition of the stock model does not go well with PITTA

-> Direct support is not available for models using 8-bit main boards (sufficient performance cannot be implemented due to insufficient memory, etc.)

In this case, if the user upgrades to a 32-bit motherboard, we provide the necessary firmware and information to support it. (cr10, ender5 plus etc with the mainboard like creality 4.2.7, skr2.0  etc)

Adaptation module will be supported for each possible model, or STL will be released so that the user can use it for a specific model with slight modifications.

3. Model support plan other than creality model

Since we started with ender3, support for this is easy at the moment, but expansion to other brand models will not be too difficult, so we plan to support it as soon as possible, and related news will be updated through blogs or user groups.

In this regard, if there is a request from users, we would like to review and proceed first, so please give us your opinion.

PITTA consists of 3 parts as shown above.

※ PITTA Base is assembled with NC processed parts, 3D printed parts(PLA Pro), and SUS processed parts. ADAPTATION KIT consists of 3D printing parts(PLA Pro).

The ideal ambient operating temperature is from 15 - 30 °C (60 - 86 °F).

② is an ADAPTATION KIT that transfers material between PITTA and 3D printer. It will be provided in a suitable form according to the type, size, and structure of the 3D printer.

Currently, the adaptation module is configured to use Ender3 V2 and Ender3 Pro. As models are added, we will sell suitable modules, and we will also share their .stl so you can make your own.

③The splitter bobbin prevents the material from kinking and keeps the spool running smoothly. Although not required, its use is strongly recommended. We will share the .stl file of the splitter bobbin, please print and use it yourself.

With the release approaching, the final performance tests are in progress.

These are tests to see how stable printing is possible with respect to the large size and 8 colors that can be printed in Ender 3 and retraction errors.

In addition, it shows the inside of the purge tower, which many people are curious about. (12/09/2021, PITTA will be launced on the market within next 2 weeks.) 

Prusa Slicer is great. It is much more convenient to use for multi-color 3d printing and PITTA supports completed. (squid game 001 o il nam)11/13/2021

Supporting BuildTech SKR main board. 

Development to support the skr board is proceeding without much difficulty.

If it is a 32-bit main-board equipped with marlin, it is expected that various support will be possible without any major issues.

Now, first release will include stock 4.2.2, 4,2,7 and SKR 2.0.  - 10/07/2021

About Kickstarter funding failure

There were a lot of thoughts, and I could organize them into a few main reasons.

First, there were not many supported printer types.

Basically, it was designed for the purpose of making it applicable to almost all FDM printers, but for actual application, necessary tasks and tests must be performed on the hardware specifications of individual printers.

First of all, it is true that there were time and physical constraints to do more of these things.

In the future, not only should efforts be made to support more machines, but also a method of allowing users to directly apply some design modifications to open source-based devices is being considered.

In addition,I need the information of more commonly used printers. It is important to know which printers are being used by as many users as possible.

Second, the price.

Some commented that it was a bit expensive. This is a really difficult problem.

If PITTA sales are high, it is possible to lower the price as the quantity increases. However, we are not in a position where we can expect such a thing in haste.

We tried to present the best price considering the price of similar products and various costs including our material cost, but I think it would be better if it was cheaper. In fact, all costs of development are not taken into account here. It's something I can't even think about right now.

However, I am wondering if there is a part that can be lowered even more.

As with the price itself, I am thinking about making the configuration more flexible.

This will be posted in more detail on this blog later.

And the third, lack of publicity.

There was too little publicity. We made a good machine, but not many people know about it.

This is the part that we need to be more aware of from now on.

The help of many people who are interested in PITTA is also desperately needed for this part.

I would be very grateful if you could give your opinion and help many people know about the photos, videos, and useful contents delivered through the blog.

We will try to sort out the big reasons for this and improve them.

Although the Kickstarter failed, the sale of PITTA is planned to proceed similarly to the Kickstarter schedule.

A shopping mall is also being prepared, and perhaps through pre-orders, we are thinking of offering additional benefits to those who apply for pre-sale.

For the time being, the blog plans to update the progress and contents in a relatively free format like writing this article.

The content will also include some technical considerations for PITTA. 

Also welcome your opinion.

Best Regards.

Regarding Stress Testing. 

Stress testing is very important.

If it goes well for the first 10 hours, I think it will be something.

Also, it seems that anything will happen in about 30 hours after I figure out the problem. It is also a wrong idea.

After about 50 hours, something else seems to happen.

However, I think it should be around 100 hours, so that it can be used moderately without any major problems in actual use.

So, I keep repeating testing until close to 100 hours. Of course, we don't just test, we have to continuously improve and reflect the problems raised here. This will increase the reliability of the product.

45 hrs test completed without any single issue (10/03/2021)

Heavy stress test. (At least over 80hrs continuous color 3d printing 10/02/2021)

Introducing PITTA - 8 color upgrade module

PITTA adds multiple color printing capacity to single nozzle FDM 3D Printers. We are working tirelessly to make PITTA compatible and optimized for a wide variety of accessible consumer 3D Printers that are open source based.

In our initial release, we will be supporting Ender 3 pro 8bit, 32 bit, and Ender3 v2. 

PITTA will be on Kickstarter soon. We’ve worked on PITTA for past 2 years and we finally have a working product(not prototype). Now we need your support to get it to production and widen support for wider range of 3D printers. 

We will continuously post more updates on PITTA including videos, pictures and technical information. So, please subscribe to our mailing list.

OUR TECHNOLOGY

We have been working on our own line of 3D Printers for the past decade. Our core products are Large Scale FDM printers and Multi-Color 3D Printers for industrial and commercial customers. Here are some examples of our prints using our own line of printers.

Now with PITTA, we are super excited to bring our technology to consumers and 3D printing communities.

FAQ

1. What is the price?

- We are expecting it to be somewhere around US$399 + shipping cost and tax 

2. What is the supported model?

- Initially, we will start out supporting Creality Ender3 Pro 8bit & 32 bit, and Ender3 V2 printers.

- We want to support more printer models and we can with more resources and time. However, we won’t be able to add more models to our initial Kickstarter campaign. However, we will continue to add more supported models in the future. And with your support, we should be able to speed it up. 

3. When can I receive the goods?

- You should be able to receive PITTA approximately 3 months after the Kickstarter campaign is completed. Delivery will also vary depending on the pledge tier. 

- Most of the 3 months will be spent on setting up the manufacturing line and production.

4. Open Source Related.

- It is open source based on Marlin. You will be able to download it to your 3D printer. We will provide specific details of how to upgrade your firmware.

- If you want to tune your printer to improve performance, you can edit the source code. However, the code for the PITTA is not open source, and a binary downloadable will be provided instead.

-  PITTA is designed to be compatible with any FDM 3D Printer. PITTA exchanges color change information directly with the printer to make the multi-color printing smooth and effortless. So, no modification of PITTA is needed.

- Further performance improvements and data for any required parts upgrade will be provided.
