Does a desktop 3D printer pay off at home?

The broad range of pos­si­bil­i­ties a 3D print­er offers is not clear to most peo­ple. This results in the most impor­tant ques­tion of all: Does a 3D print­er at home pay off? The answer to this is “yes”, at least if you believe an Amer­i­can study.

The arti­cle with the title “Emer­gence of Home Man­u­fac­tur­ing in the Devel­oped World: Return on Invest­ment for Open Source 3‑D Print­ers”. The researchers includ­ed cheap as well as expen­sive prod­ucts from a vari­ety of sup­pli­ers and for a vari­ety of appli­ca­tions. Although the prod­uct sound extreme­ly sim­ple and straight­for­ward in the paper, it takes a lot of time and ideas.

They looked at a peri­od of 5 years and cal­cu­lat­ed the cost dif­fer­ence. For exam­ple, costs for object A were com­pared between the 3D print­ed and con­ven­tion­al prices. The result: a return of invest­ment larg­er than 100% after 5 years (invest­ing $500 and sav­ing $1000).

Does a 3D printer pay off and what objects are being printed?

A few of the fol­low­ing exam­ple prints illus­trate the work of the sci­en­tists at Michi­gan Tech­no­log­i­cal Uni­ver­si­ty. It is impor­tant to men­tion, how­ev­er, that some assump­tions have been made and com­plex mat­ters dis­re­gard­ed. For exam­ple, although you can print a cell phone case, the qual­i­ty and feel­ing are com­plete­ly dif­fer­ent even with flex­i­ble mate­r­i­al. There­fore, even most mak­ers still buy phone cas­es instead of print­ing them out.

Oth­er Object exam­ples are:

  • Spoon hold­ers
  • Par­quet cor­ners
  • Glass hold­ers
  • Show­er­head
  • Mobile Phone Case
  • Poke­balls
  • Ski mount for GoPro
    (to what extent a per­son trusts his GoPro 3‑dimensionally print­ed prod­uct remains open for each per­son)

Criticism of the study: Is a 3D printer profitable?

Although we want to empha­size the state­ment that 3D print­ers are prof­itable and not just a toy, our blog post should not be one-sided. In the end, a 5 year prof­itabil­i­ty will be bare­ly sus­tain­able due to defects or com­plete­ly new prod­uct gen­er­a­tions (fea­tures). You do not always need the lat­ter, but there is insuf­fi­cient knowl­edge about future inno­va­tion and their effects on the cur­rent prod­ucts. Fur­ther­more, it is dif­fi­cult to eval­u­ate one’s own use­ful­ness and knowl­edge for per­son­al­ized 3D print­ed objects. For one, not every­one has the imag­i­na­tion about the print­ing pos­si­bil­i­ties and most can­not design cus­tomized objects for their own needs.

Anoth­er point is that the researchers did not con­sid­er peo­ple who will still pre­fer tra­di­tion­al­ly pro­duced prod­ucts despite hav­ing a 3D print­er. Let’s say some­one needs a sleeve for his phone and designs as well as prints a case. How­ev­er, this it will like­ly be too hard and not fit the mobile phone. After a sec­ond attempt, the user decides to buy a high-qual­i­ty case around the cor­ner in the store. You see, in some cas­es peo­ple lose time and mon­ey with 3D print­ing which is why adjust­ments must be made in the approach of the study.

Positive aspect of the study

To cor­rect and ana­lyze the ques­tion of “Prof­itable 3D print­ers” we have to break the usu­al silo think­ing. Com­pa­nies must stop think­ing of their own 3D print­ing expe­ri­ence which is far from the actu­al customer’s lev­el. There­fore, we find it extreme­ly pos­i­tive that the authors Emil­ia E. Petersen and Joshua Pearce took the dis­ad­van­tages of a begin­ner into account.

A per­son who only starts with 3D print­ing can­not keep up with an expe­ri­enced mak­er, as it requires a lot of train­ing and prac­tice. For this rea­son, the researchers let novices test and used these obser­va­tions in form of data with­in the study. For this rea­son, we believe the arti­cle is rep­re­sen­ta­tive of the total pop­u­la­tion in West­ern coun­tries with regards to the under­stand­ing of the tech­nol­o­gy.

Conclusion: Does a 3D printer really pay off?

This arti­cle on the prof­itabil­i­ty of 3D print­ing is an impor­tant piece of work, draw­ing a pic­ture of the future with 3D print­ers in our homes. We wel­come the efforts for quan­ti­ta­tive analy­sis in this area and hope for more works in this direc­tion. Nev­er­the­less, the study still has improve­ment poten­tials as they did not include price, qual­i­ty and con­ve­nience fac­tors for the com­par­i­son between con­ven­tion­al and 3D print­ing objects.

The next step may be a study that allows can­di­dates to choose between dif­fer­ent solu­tions with regards to qual­i­ty, price and con­ve­nience. This gives researchers more real­is­tic val­ues than the cur­rent the­o­ret­i­cal num­bers not includ­ing the deci­sion fac­tor.

Anoth­er pos­si­ble assess­ment could also be long-term learn­ing effects and ben­e­fits of the tech­nol­o­gy for your­self or chil­dren. This has also been the case with com­put­ers over the last few decades. This is just an idea that we want­ed to share with researchers and Mak­ers in our com­mu­ni­ty.
