A sexbot company has shown off heads made for lifelike robots with a 3D printer for the first time at a trade fair in China.

Previously, silicone components for sexbots -- the exterior parts rather than internal components -- had to be moulded from casts.

The robotic body attached to the new heads is for a customer service 'hostess' droid, rather than for sex

This is a complex and time-consuming process with high set-up costs for any given component.

Changing to 3D-printing means you no longer need to make a mould, but can instead just use a much cheaper and quicker 3D-scan.

The firm has headed off some concerns by promising that only "consenting" models' faces will be used, saying that pervy customers will not be able to send in scans or requests for people to be copied, according to industry watchers Sextechguide.

Making the bots cheaper and more accessible increases the risks of addiction becoming a more widespread problems.

The new heads are created without the need to create expensive moulds, meaning that it's much easier to make droids look different

What is a sex robot? Robots already build our appliances, clean our homes and make our food – but now they're about to change how we get jiggy. Sex robots are essentially realistic dolls that have sophisticated movements and "areas" that closely mimic humans so that they can romp. Prof Noel Sharkey, chairman of the Foundation for Responsible Robotics, said guilt-free threesomes was just one of the potential uses for sex robots. Others include “teledildonics” - wireless technology which allows a person to stimulate their partner remotely and already exists in vibrators on the market. Sex bots will become hyper-realistic with features such as built-in heaters to create the feeling of body warmth. They will also have sensors to react to your touch. One company is even developing a head that can speak, smile and sing for its robot sex dolls. Sex doll Harmony claims to be the first to offer an "emotional connection". Experts say these specialised robots will start to appear in ordinary homes in the next decade.

Sexbots have "the same function as alcohol for problem drinkers...It is an escape from the self. This is the psychology behind it," according to Psychological therapist Dr Thaddeus Birchard, talking to Daily Star Online.

Robotics expert Joe Snell has also previously claimed that sex robots may become addictive as they provide a readily available outlet to "accommodate" people's addictions.

Snell cited the fact that you can program the droid's to meet each individual owner's sexual fantasies as a particular issue -- and the ability to more cheaply and effectively customise them to fit individual tastes will clearly exacerbate this problem.

Addiction isn't the only risk, with security experts recently revealing the dangers hackers might pose via your personal droids.

And experts recently expressed concern that the rising popularity of sex robots risked turning Japanese people into "an endangered species".

For those who are more blasé about the risks, there are a growing number of sex robot brothels and the like offering a chance to try out cyberlove for less than £100.
