3D desktop metal printer

I have developed a technoligy to make a tru desktop metal printing printer viable.

Lets see how that looks in the market 

What it will do right now:

• It is desktop-sized and lightweight. 
• It can print a stream equivalent to an FFF printer, with a nozzle range from 1 mm down to 0.4 mm. 
• It operates at roughly one-third the speed of FFF (PLA). 
• The standout feature is the price — for me to build a working unit, it costs around £400. 
• It only requires a standard 13-amp outlet. 
• Very low cost of consumables. 
• Very low cost of raw materials. 
• The workflow is similar to FFF, making it easy for the market to understand and adopt. 
• Stainless steel is my primary material, but it can also process ferrous and non-ferrous metals such as copper, aluminium, steel, and even tungsten. 

What it will not do:

• It cannot yet run a full print in the conventional sense. While the head can print and produce a result, it cannot complete a full, continuous print job. 
• The limitation is software-related. I currently do not have the expertise to write the slicer software specifically for this unit, nor to modify existing firmware to resolve certain quirks. 

Context:

• This is largely an academic limitation. The printer system itself is functional — it can be likened to having a complete FFF printer (hardware and print head), but without the software needed to fully operate it.

You can see the potential of this technology, and I am offering it for sale.

Based on prior experience, I have adopted a simple and controlled evaluation process.

Process:

• I will present a physical sample that demonstrates the printer’s capability. 
• The sample is for visual inspection only and may not be taken away or subjected to further analysis. 
• If you decide to proceed, full payment must be made upfront. 
• Once funds are received, I will run the machine and reproduce the demonstrated result. 
• This demonstration confirms performance, and the transaction is then considered complete. 

Further Development (Optional):

The system is hardware-complete, with current limitations relating to software — specifically slicer development and firmware refinement.

If required, I am open to working with your engineering team to complete this stage. This would be subject to separate discussion and agreement.
